1 Possible compatibility problems with earlier versions marked with '*'.
3 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
4 of name and value - ignoring empty lines and comments.
6 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
8 Added odr_get_element_path which returns current element path for an
9 ODR handle. This utility is useful in error handling or user-defined
12 Added ODR_PRINT utility odr_set_stream which is is a more generic
13 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
14 to a write function and pointer to close function. The close function - if
15 non-NULL - will be called during odr_destroy.
17 Fixed bug in CCL parser where truncation char was not removed from
18 right side when truncation=both was in effect.
20 Fixed CQL parser to use unsigned chars (occurred on MS .NET).
24 Fix buffer overrun in CQL parser when dealing with proximity (%).
26 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
27 to UTF-8/UCS conversion is now only based on codetables.xml.
29 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
33 Add support for more "commit changes" in ZOOM (uses Extended Services).
35 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
38 Yet another small fix for configure of SSL.
42 Fix SSL libs for configure when --with-openssl=DIR is given.
46 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
48 SSL comstack now uses yaz.pem certificate file on server side
49 by default. Certificate filename can be configured by calling
50 comstack function cs_set_ssl_certificate_file before cs_bind is used.
52 Fix bug regarding multiple calls to ZOOM_connection_connect.
54 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
56 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
57 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
59 ZOOM now allows inspection of X509 peer certificate for verification.
60 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
62 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
63 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
64 as "modular" but it simplifies things.
66 Added cs_get_peer_certificate to that returns peer X509 PEM.
68 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
69 NULL if SSL is unavailable.
71 Documentation about MARC decoding tools.
73 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
77 Rename CHANGELOG to NEWS to follow GNU style packing.
79 Fix bug with missing initialization of member in init_diagnostics.
80 This bug affects threaded version of GFS server.
84 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
87 Ensure zlib.dll is packed with Windows install.
91 Fix encoding of xsd:string to use text instead of CDATA.
93 Fix endless loop in CQL parser with unbalanced ".
95 Use a more compact way to store MARC-8 conversion tables.
97 --- 2.0.16 2004/03/16 Debian only
99 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to

115 Update NS and use default NS for SRW diagnostic elements.
117 --- 2.0.13 2004/02/23
119 Implement ZOOM_resultset_cache_reset which resets record cache.
121 Implement ZOOM_resultset_sort which sorts a result set.
123 Implement chunked HTTP transfer.
125 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
127 --- 2.0.12 2004/02/16
129 Added member 'schema' to bend_explain_rr structure so that backend
130 can specify explain record identifier. Defaults to Zeerex 2.0.
132 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
134 --- 2.0.11 2004/02/16
136 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
139 Added init command for yaz-client which sends "extra" init request.
141 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
142 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
144 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
146 Make ZOOM error code for "invalid query".
148 Fixed compilation for SSL which wasn't properly enabled for all platforms.
150 --- 2.0.10 2004/02/05
152 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
155 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
157 Added option -p <file> to make Generic Frontend Server to write PID file.
159 Added option -D to put Generic Frontend Server in background on its own.
161 Make ZOOM C recognize option "password". If unset, "pass" is used
162 (for backwards compatibility).
164 Fixed a bug in Generic Frontend Server that could make it crash if a
165 client sets characterSetNegotation bit, but didn't pass negotiation stuff
168 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
169 Must be issued before open, in order to be in effect.
171 --- 2.0.9-6 2004/01/12 Debian/Windows
173 Make the SRU server more picky WRT unknown params, etc.
175 Bug fix: ZOOM scan response didn't return displayTerm - when present.
177 New YAZ client command, options, that sets Z39.50 options.
179 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
180 options from a string of tokens (one token for each option bit).
182 Update SRW diagnostic code messages.
184 --- 2.0.9-5 2004/01/07 Debian/Windows
186 Handle user defined stylesheet for SRW/SRU.
188 --- 2.0.9-4 2004/01/06 Debian/Windows
190 Fix bug in decoding of Content-Length.
192 --- 2.0.9-3 2004/01/06 Debian/Windows
194 Fix a bug with decoding of XML packed records.
196 --- 2.0.9-2 2004/01/05 Debian only
198 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
200 Fix bug in SRW/SRU diagnostics decoding.
204 Fixed bug in Generic Frontend Server which could drop records exceeding
205 preferred message size. Reported and fixed by Irina Dijour.
207 Fixed calculation of package size for structured records in Generic
208 Frontend Server. Reported and fixed by Irina Dijour.
210 Fixed namespace for SRW/SRU diagnostics.
212 Fixed SEGV in yaz-client that occured for HTTP connection errors.
216 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
217 this version is incompatible with version 1.0 and older YAZ SRW/SRU
220 CQL changes to reflect recent changes to the specification:
221 * Documentation talks about context sets instead of index sets.
222 * Documentation talks about indexes instead of qualifiers.
223 * The CQL-to-PQF transformer's configuration file now uses
224 "index.set.name = <attributes>" instead of the old form
225 "qualifier.set.name = <attributes>". (Both forms are still
226 understood but the latter is deprecated.)
227 * CQL terms with no explicit index specified are now interpreted as
228 cql.serverChoice instead of srw.serverChoice (which of course
229 behaves exactly the same.)
233 MARC conversion can now generate ISO2709 output in another
234 character set. yaz-marcdump uses this facility if you invoke it
237 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
238 functions from there can be used from C++.
242 Frontend server now transfers memory from decoded packages to stream
245 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
246 references to show up.
248 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
249 the ZOOM Abstract API. The older names for the same options are still
250 also supported for the benefit of old applications.
252 ZOOM-C supports "implementationId" and "implementationVersion" options
253 to go along with "implementationName". These allow the user code to
254 specify identification strings to be sent to servers.
255 Add OID for the new ExtLite attribute set.
257 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
258 as requested/supplid by Ere Maijala <ere@atp.fi>
260 For generic frontend server, reverse the order of
261 "toolkit-supplied / application-supplied" strings sent as implementationId,
262 Name and Version. Also, remove the spaces around the slash. This brings
263 the GFS in line with the behaviour of ZOOM-C on the client side.
265 Add function ZOOM_scanset_display_term.
267 yaz-client shows scan displayTerm if present.
269 Utility yaz-iconv is now installed by default along with the man page
272 Extend configure check for OpenSSL to use pkg-config where available (such
275 Incorporate patch by Morten Bogeskov which allows a Unix file socket
276 server to specify uid/gid/mask for socket using the format
277 unix:[user=uid,][group=gid,][umask=mask,]file=path
278 If file= is omitted the existing format is assumed, e.g.
280 in which case the mask is 0666 (rw for everybody).
282 Major restructure of YAZ source. All source in libyaz is in src directory.
283 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
284 util (utility programs such as ASN.1 compiler, yaz-marcdump).
286 Added man page for utility yaz-marcdump (used to be called marcdump).
287 yaz-marcdump is installed by 'make install'.
289 Fixed a memory leak in Generic Frontend Server that occurred when decoding
290 of incoming package failed.
292 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
294 Change prototype of odr_perror: add const to message string.
296 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
298 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
299 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
300 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
301 DNS lookup. There should not be any compatibility problems with this
302 assuming that blocking=1 or 0 is used.
304 Fix bad reference in UNIX comstack in function cs_addrstr.
306 Fix for compilation on AIX.
308 The generic front-end server (server/seshigh.c) now supports returning
309 Init diagnostics to the client in User-information-field, in
310 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
315 Allow any CQL relation (not just all,any,exact,scr).
317 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
318 that features the same UI.
320 Implemented command update0 in YAZ client which is equivalent to
321 update but uses old of Ext Update ASN.1.
323 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
324 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
325 Previously no OID was used for this info.
327 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
328 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
329 returns 'malformed search term' otherwise.
331 SortResponse member resultCount now set to NULL in sort handler of
334 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
337 Add three new utility functions for translating OIDs between various
338 formats -- symbolic name such as "Usmarc", minus-1-terminated int
339 arrays and dotted strings such as "1.2.840.10003.9.5.1":
340 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
341 char *oid_to_dotstring(const int *oid, char *oidbuf);
342 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
344 Reverted modifications for ES Update definition for z_IU0Update
345 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
346 is back to YAZ 2.0.2.
348 String value attributes for CCL parser.
350 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
351 which their FirstSearch server returns in Init responses, sometimes
352 carrying useful diagnostic information when Init fails. This has the
353 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
354 "z39.50/oclcui.asn", where its definition is somewhat different from
355 what OCLC document on their web-site, as required to interoperate with
358 Support for anonymous authentication in yaz-client. Use the command
361 * Fix the OID of the Index Data-local "admin" Extended Service from
362 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
363 the 1000, which indicates a locally-defined OID, was a mistake.
367 Fix CCL directive @case handling so that it affects string match for
368 both CCL keywords and qualifiers.
370 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
371 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
372 Decoder has been updated with ASN.1 changes as listed in
373 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
374 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
375 z_IUUpdate, remains unchanged.
377 ZOOM_record_get may now return a record in a specific character set.
378 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
379 "from" is the character set of record as returned by target. "to" is
380 the character set to be returned. If omitted, "to" is UTF-8.
382 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
384 New ODR utility, odr_getelement, which returns name of element for
385 which encoding/decoding failed.
387 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
388 in cases where a required element was omitted.
390 Bug fix: some MARC8 sequences were not converted.
392 New ZOOM option "step" which specifies number of records to be
393 retrieved in one chunk. Used in conjunction with "start" and "count".
395 SRW support for yaz-client. Use scheme http: to use it, e.g.
398 yaz-client no longer does (un)intelligent character set conversions
399 by default. Can be enabled with charset and marc_charset commands.
401 xmalloc trace fix for 64-bit systems such as DEC alpha.
403 Solaris 2.6 compile fix.
405 New function, cql_strerror() translates SRW error codes, as returned
406 by cql_transform_error(), into human-readable English strings. Used
407 in yaz-client diagnostics when appropriate.
409 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
410 converts it into a type-1 query which is sent to the server. This
411 makes CQL available for use with all Z-servers, as opposed to the tiny
412 minority that can handle CQL queries themselves.
416 New Debian package layout similar to the Redhat Package layout.
418 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
419 and search result respectively.
423 Redhat package is now several packages: libyaz (runtime libraries),
424 libyaz-devel (development and documentation, and yaz (utility programs).
425 Package spec file by Morten Bøgeskov.
427 New member 'schema' in struct bend_fetch_rr which the name of requested
428 schema (SRW/SRU) for record (or NULL if none was given). The fetch
429 handler MAY set this to reflect the schema of the returned record.
431 New member 'display_term' in struct scan_entry. GFS now sets member entries
432 and allocates scan entries to be filled by user scan handler. In previous
433 version, entries member was allocated by the scan handler. That still works,
434 but the GFS will ignore member display_term - assuming it was NOT set by
435 the handler. The fact that the GFS now allocates the entries both allows
436 for new members and makes a scan handler easier to write.
438 Fix CQL lex buffer overflow.
440 SRW/SRU recordPacking. For SRW default recordPacking is string. For
441 SRU default recordPacking is string.
443 SRU protocol support for frontend server.
445 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
447 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
449 Added scan for the ZOOM shell (zoomsh).
453 * String Identifers for Schemas (Amendment 5).
454 http://lcweb.loc.gov/z3950/agency/amend/am5.html
455 Old definition for schema
456 Odr_oid *schema; /* OPT */
461 Z_InternationalString *uri;
462 #define Z_Schema_oid 1
463 #define Z_Schema_uri 2
466 * resultCount parameter to Sort Response (Amendment 1).
467 http://lcweb.loc.gov/z3950/agency/amend/am1.html
469 Support for SRW 1.0 over HTTP. This is an optional feature and
470 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
473 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
474 on the same port. SRW SearchRetrieveRequests are mapped
475 to bend_init,bend_search,bend_fetch,bend_close.
477 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
479 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
480 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
482 ZOOM connections are SRW based if schem http is used for hostname
483 in connect, e.g. z = ZOOM_connection_new("http://myserver");
484 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
486 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
487 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
488 distance=n, order=true/false, relation=le, prox unit=word. If
489 n is omitted, distance 1 is used.
491 Fixed problem with C compiler include path in wrong order.
493 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
494 on Solaris. Patch from Ko van der Sloot.
496 New MARC decode API. All new functions operate on a yaz_marc_t
497 handle. The most important new functions are: yaz_marc_create,
498 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
499 decode and destroy respectively. Decoder can produce formats
500 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
501 include/yaz/marcdisp.h.
503 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
504 to UTF-8, UCS-32, wchar_t or Latin-1.
506 * Prototypes for yaz_iconv_-functions moved to separate header
507 include/yaz/yaz-iconv.h.
509 Make a few private functions 'static' in unix.c. This prevents
510 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
512 For ZOOM connection, the options targetImplementation{Id,Name,Version}
513 are set when Init Response is received.
515 New function ZOOM_connection_error_x similar to ZOOM_connection_error
516 but returns diagnostic set as well.
518 New function yaz_strerror which is a portable wrapper for
519 strerror/strerror_r/GetLastMessage.
521 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
522 is returned for MARC. If type is "oai", then OAI MARC is returned.
524 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
529 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
531 Fix bad race conditions on SIGTERM and terminate gracefully in
534 Move retrieval (data1) module to Zebra since nobody seems to be
537 Add GRS-1 render for ZOOM using same format as yaz-client.
541 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
543 Fix broken ESpec handling in data1 module.
545 SGML reader parses comments and makes them part of the data1 tree.
547 Added several type casts so that YAZ compiles as C++ code.
549 ZOOM didn't handle PDU encoding failures properly.
551 Added more Bib-1 diagnostics (approved extensions).
553 GNU configure: better check for iconv.
555 More portable use of accept, getpeername. Check for socklen_t. Use
556 int/size_t if socklen_t is not defined.
560 PQF parser rejects bad queries - including those with extra
561 characters in them. PQF parser used to silently ignore that.
562 Cleaner API for PQF added, which allows you to get detailed
563 error information for bad queries (see yaz/pquery.h).
565 Fixed bug in ZOOM_record_get for type "database".
567 Implemented mini iconv library supporting conversions between
568 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
570 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
574 Fixed ZOOM C record cache so that preferredRecordSyntax and
575 elementSetName is used to check for already fetched records.
579 Added three members in bend_initrequest structure to facilitate
580 character set negotiation.
582 Fixed a bug in frontend server that could cause indefinite
583 loops under rare conditions.
585 Revised character set utilities (charneg.h) so that encoding
586 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
588 For PQF, directive @term <type> sets term type for Scan/Search.
589 Here <type> is general, string, numeric, null. The term type
590 is inherited - just like @attr.
592 New call odr_set_charset that sets character set conversion for
593 international-strings on a ODR stream. Prototype is:
594 int odr_set_charset(ODR o, const char *to, const char *from);
595 The InternationalString is still represented as C string in YAZ
596 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
597 won't). On the protocol level, you can use any encoding.
599 Support for UNIX sockets in ZOOM.
601 Solaris recv sometimes returns errno == ENOENT. It is treated as
602 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
604 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
605 both client and server. Code by Morten Bøgeskov.
609 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
610 that they can be used directly from Visual Basic. You must recompile
611 your windows APP if you're using ZOOM.
613 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
614 Commands "lang" and "charset" sets language and character set respectively.
615 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
616 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
618 Attributes from multiple CCL fields may be OR'ed rather than merged
619 using directive "@field or". Fields are still merged by default -
620 equivalent to "@field merge".
622 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
625 Fixed bug in zget for parameter ExtendedServicesResponse.
631 Added PQF feature: '@attr type=value' may be written as '@type=value'.
633 Client displays USR.1:SearchResult-1 (hits per term).
635 Additional Search Info for search in Generic Frontend Server.
637 Fixed CCL parsing of "field=s".
639 WIN32 installer - using the excellent NSIS software from nullsoft.
641 Fixed CCL parsing of "field = - <number>".
643 Added function yaz_marc_decode that decodes MARC for line mode
644 display or XML (similar to that used by JZKit).
646 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
647 Z39.50. But ISO/ILL was, however.
649 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
650 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
652 http://lcweb.loc.gov/z3950/agency/amend/am2.html
653 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
657 New YAZ client features: Command completion and new commands:
658 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
659 Code provided by Jacob Poulsen.
661 New call oid_trav, that visits all registered OIDs via callback.
663 Function ZOOM_record_get now returns const char pointer rather than
664 void pointer. It saves a lot of type casts.
666 For YAZ client, command "auth" now allows you to set authentication
667 in IdPass style. It is enabled when three tokens are given - order
668 is user, group and password.
670 Fix memory leaks in MARC record handling for ZOOM.
672 New option for YAZ client, -k <kilobytes> that sets
673 maximum record size. Similar to -k option for generic frontend
674 server and yaz-ztest.
676 More fixes for scan. Non-zero stepSize handled. OID's fixes.
678 Prefix query parser reports "fail" when bad attribute set is given.
680 Fix in MARC decoder. Proximity logging. Fix for attribute set
681 in scan handler for server. Patches by Shigeru Ishida.
683 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
686 Configure option --with-openssl=<dir> now works when a directory is
687 specified. Patch provided by Morten Bøgeskov.
689 New option for YAZ client, -u <auth>, that sets authentication.
691 ZOOM fix: error information was sometimes "missing", since error
692 was cleared/reset too when it shouldn't.
694 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
698 Scan for ZOOM API. New object ZOOM_scanset. New functions
699 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
700 ZOOM_scanset_destroy.
702 New ZOOM function, ZOOM_connection_last_event, that returns type
703 of last event (such as "receive data", "send data", "apdu received",
706 New ZOOM option, schema, that specifies schema for retrieval.
708 New CCL feature. Qualifiers can be aliases for one or more
709 other qualifiers (if more than one is given, OR is used).
711 ZOOM uses named result sets if target supports it.
713 Two new YAZ client commands: . (dot, which sources a script of YAZ
714 client commands), and ! (to execute shell command.). Implemented
717 Working on Debian packages.
721 YAZ client enables named result sets only if target supports it.
723 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
725 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
726 with key="host" to get same result.
728 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
729 Function Z3950_resultset_record(s) returns references to records
730 "owned" by resultset. To become owner use Z3950_record_clone.
732 Function z_ext_record handles Extended Services. Thanks to
737 CCL Parser fix: ignore token comma when dealing with and-lists.
739 Documentation updates for COMSTACK.
741 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
742 Changed prototype Z3950_records. For some functions, int parameters
743 were changed to size_t.
745 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
748 New MARC decode/display function, marc_display_exl, which properly rejects
749 non-ISO2709 records. YAZ client uses it.
753 Fix bug: local attribute set wasn't set correctly in PQF strings.
757 * Old Z39.50 codecs no longer supported.
759 Added ZOOM C binding. See http://zoom.z3950.org/
761 Renamed states for COMSTACKs to avoid confusion with events.
763 Implemented cs_look and proper cs_rcvconnect.
765 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
767 Configure detects POSIX threads on OpenBSD.
769 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
770 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
772 When error is returned from present handler, non-surrogate diagnostic
773 is returned in present response (and fetch handler is no longer called).
775 * Minor adjustments to pquery parser (PQF). Token characters may be
776 escaped by using backslash (C-style).
778 PQF parser allows string attribute values to be specified. For @attr,
779 non-numeric characters after the equal-sign are treated as strings
780 (e.g. @attr 9=title).
782 CCL trunction character may be defined (@truncation in file)
784 * function zget_ExtendedServicesRequest sets waitAction to
785 waitIfPossible (was wait).
787 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
790 CCL operator names may be set in field definition files (CCL_bibset).
791 See ccl/bib1 for an example.
793 Fixes in ASN.1 compiler for C++ compatibility.
795 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
796 and "op_or" to avoid conflict with C++.
798 Fixed problem with GNU readline detection on Redhat 7.0.
800 Added step-size for Scan backend handler.
802 Fixed bug that made the frontend server crash when no attribute
803 set was specified for scan.
805 Front-end server automatically switches to original working directory
806 when installed as an NT service. Previously -w had to be specified to
809 Added extended attributes for retrieval module (data1), so that data1
810 records carry d1_readXML/SGML attributes. d1_read also supports
811 null-data rules ( <tag/>)
813 On UNIX when POSIX threads are available, a separate library libyazthread
814 is created. Programmers should link with that library and the yaz library
815 when using threads. The reason for the split was that some applications
816 on Linux, such as Apache, doesn't work well when using shared objects that
819 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
820 (or any frontend server) in SSL mode by specifying ssl: followed by
821 address. Only tested on UNIX.
823 Added feature for CCL module. Virtual structure s=al or s=ol generates
824 and-list and or-list respectively instead of phrase search.
828 * Added prefix "yaz_" for the functions log_init.., log_file.. and
829 log_mask_str. This was done to avoid name conflicts with other libraries
830 (such as other PHP extensions).
832 Added raw OID member for preferred record syntax (request_format_raw)
833 and returned record syntax (output_format_raw) for backend fetch method.
835 Config file yaz-config now accepts options so that it returns specific
836 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
838 Shared library support for UNIX using GNU libtool.
840 * Modified backend interface. Request/Response struct's replaced by
841 one read/write C struct. For example bend_fetchrequest and
842 bend_fetchresult have been replaced by single bend_fetch_rr struct.
843 Every handler - even search has to be registered in bend_init
844 handler. This means that the YAZ library no longer refers to
845 external functions and it makes it possible to make the whole
846 thing a single DLL/SO.
848 Added Segment handler for backend server.
850 Added Zmbol/Zebra administrative functions to YAZ client.
852 Threaded frontend server on UNIX (when POSIX Threads are available).
853 Starting the server with option -T enables multi-threading.
857 Added configure option --enable-comp/disable-comp to control use
858 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
859 located in sub directory asn.
861 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
862 in ${exec_prefix}/bin along with the other programs yaz-client and
865 GNU automake used to maintain makefiles.
869 Changed retrieval module so that we can load records with no abstract
870 syntax defined. Tagpaths in these records are fully composed of string
873 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
877 On UNIX, the generated makefile now supports a proper 'make install'.
878 The prefix can be set via GNU configure to set the install location
879 (default is /usr/local).
881 * YAZ programs client and ztest were renamed to yaz-client and
882 yaz-ztest to avoid conflicts when users install YAZ in "standard"
883 locations, such as /usr/bin,/usr/local/bin,etc.
885 * YAZ Header files were moved from include to include/yaz. YAZ Header
886 files are referred to as include <yaz/log.h> rather than <log.h>.
887 The YAZ include path (-I ..) is therefore the same as before. Programmers
888 should update their #include statements or use -Ipath/include/yaz
889 instead. The main motivation for doing this change is that YAZ header files
890 can be installed in "standard" locations /usr/include,/usr/local/include
891 without introducing conflicts, since ALL YAZ header files are stored
892 in subdirectory yaz (under /usr/include for example).
894 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
895 rather than project/workspace files. We switched because project files
896 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
899 Changed name of logging function, logf, to yaz_log, to prevent name
900 clash with some math-log functions. The YAZ header log.h defines logf
901 to yaz_log (#define) so there should be no incompatibilities by this
904 Added bend_start/bend_stop handlers for server. These handler are
905 called on start/stop of server. For windows they are called whenever
906 a service is started/stopped.
908 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
909 a fairly small ASN.1 compiler written in Tcl. The compiler is located
910 in util/yc.tcl. The auto-generated C code structures are, in a few
911 cases, incompatible with the old decoders. There are differences in the
912 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
913 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
914 The preprocessor variable ASN_COMPILED is defined when the compiled
915 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
916 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
917 wish to use the old encoders/decoders you can specify --disable-yc
920 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
921 version so that it supports both new - and old version of DB Update
923 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
924 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
925 change. The name parameter can be set to 0 in which no name is specified
926 for the construction. The macros odr_implicit and odr_explicit sets name
927 parameter to zero for the construction involved. New macros
928 odr_implicit_tag and odr_explicit_tag are similar to the others,
929 except that a name parameter is added. For programmers' that don't use
930 ODR they probably only need to change the call to z_APDU and z_External.
932 Added access control facility by interfacing the TCP wrapper library.
933 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
934 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
935 name of the daemon and enables the access control as specified in
936 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
938 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
939 den Dool <H.M.vdnDool@kub.nl>.
941 Added reference ID parameter to most functions in server API - refer
942 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
944 Changed name of ccl library to libccl.a (was ccl.a).
946 Fixed bug in decoder for Explain (Category TargetInfo).
948 Added support for GNU readline in client. Thanks to Jacob Poulsen
949 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
951 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
952 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
953 IMPLEMENTATION! This change was made to the development version before
954 the ZIG decided to retract the amendment. If any users MUST be
955 compatible with the original Update definition, PLEASE CONTACT US, and
956 we will include a separate definition corresponding to the old Update
957 ES. Note that because of the change to the ASN.1 of the
958 TaskPackageRecordStructure we cannot define a single structure that
959 will support both versions.
961 * Added const modifier to buffer parameter for some ODR/BER encoding
962 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
963 completeWAIS, odr_dumpBER.
965 Fixed bug in client.c which caused a crash when a scanResponse didn't
966 contain positionOfTerm.
968 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
969 * will cause an error in a client if a non-YAZ target sends both a
970 * list of Scan entries and non-surrogate diagnostics.
972 Retrieval module enhancements. Tag sets may be typed in the reference
973 to it. From the .abs-file the "tagset" directive takes a third optional
974 integer type for the tag set referenced. From a .tag-file the "include"
975 directive takes a third optional type as well. The old "type" directive
976 in the tag set itself is still recognized but acts as the default type
979 Backend interface change. Individual Scan terms returned from bend_scan
980 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
981 in include/backend.h.
983 Retrieval module enhancements. Multiple tag sets and attribute sets may
984 be specified in abstract syntax specs. Revised the error/warning for
985 logging messages reported by the retrieval module when reading the
988 Object Identifier system (oid_..) changed. The API is backwards
989 compatible but the oid-routines now allocates new OID's when needed.
990 Raw OID's may be specified in oid_getvalbyname.
992 YAZ now uses GNU configure to generate Makefile(s).
994 * Minor changes in some of the member names of DeleteResultSetRequest and
995 DeleteResultSetResponse. See include/proto.h.
997 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
998 and added member 'languages' in TargetInfo (which was missing).
1000 Changed the way attribute sets are handled in the retrieval
1001 module. These are now cached, just like the abstract syntaxes
1004 Changed YAZ so that it links with compiled ASN.1.
1006 Added Explain-schema definitions and mapping routines. The following
1007 Explain categories have been implemented: AttributeDetails,
1008 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1010 Fixed minor bug in Windows version of Server Library.
1012 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1014 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1016 Added EXTERNAL: UNIverse Resource Report (non-standard).
1018 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1019 ENUMERATED and SET OF.
1021 * Added 'const' to some of the char pointer arguments for the
1022 functions, data1_read_node, data1_getelementbytagname,
1023 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1026 Fixed bug in data1_insert_taggeddata - the last_child member of
1027 parent wasn't initialised.
1029 * Changed data1_read_record and data1_read_node so that the supplied
1030 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1031 doesn't refer to any parts of the "SGML"-buffer.
1033 Fixed bug in server library (Windows version of statserv_remove).
1035 * Changed code so that it compiles as C++. The type definition
1036 of Odr_fun which is a member of Odr_arm was changed. The result is,
1037 that an explicit typecast is needed for the fun pointer when
1038 using Odr_arm - as in:
1039 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1041 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1043 Implemented the new structured date and time definition as approved
1044 by the ZIG. Added schemaId element to the specificTag in Espec-1
1045 (also approved at the last ZIG). Thanks to RVDM.
1047 Added some Object identifiers (RVDM).
1049 Changed the Update Extended Service (RVDM).
1051 Added command "refid" to client which specifies referenceId for
1052 the following requests.
1054 Implemented extended service handling for server. See ztest.c
1055 for an example as well as backend.h. New handlers are registerd
1056 in the Init handler.
1058 * Changed interface for sort in server.
1060 Added new members to statserv_options_block. It allows a server
1061 to read options from another source than just the command line. Thanks
1062 to Charles Woodfield.
1064 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1065 renamed to zboolean. Some C++ compilers complained about the name.
1067 Minor changes to gils.abs. Added index 's' (sort) on title
1068 and date/time-last-modified.
1070 --- 1.4pl2 1998/1/30
1072 Fixed bug in server library regarding inetd mode (-i). This bug
1073 was introduced by release 1.4.
1075 --- 1.4pl1 1998/1/29
1077 Added sort facility in client and backend server interface.
1079 Fixed problem with dependencies in Makefile(s).
1081 Fixed bugs for encoders/decoders of extended services and
1084 Implemented sub-tree feature for schemas. Sub-trees are
1085 referenced in *.abs-files. See explain.abs for an example
1086 of the use of this feature.
1088 Modified bib1.att; local attributes for ANY didn't include
1089 ANY itself (only affects use of the retrieval module).
1091 Fixed bug in plain SGML reader in function data1_read_node:
1092 tags with prefix "var" was incorrectly interpreted as variants.
1094 Added feature "sub-schemas" to enable references to - and definitions
1095 of - group of elements.
1097 * Removed member parent from type data1_element (in data1.h).
1099 Implemented function odr_nullval() that returns the value of
1102 * Removed member num_children from data1_node (in data1.h).
1104 Made NT service interface part of the server library. The
1105 function statserv_main uses the NT service when required and
1106 calls the statserv_start / statserv_close routines.
1108 Routine zget_SearchRequest and zget_PresentRequest fills
1109 resultSetName/Id member with "default" instead of "Default".
1111 Fixed memory leak in server. Request queue member wasn't freed.
1113 Fixed nmem_exit so that memory is freed.
1117 Revised the CCL parser utility to be thread safe.
1119 Added function, oid_ent_to_oid, to replace the function
1120 oid_getoidbyent, which is not thread safe.
1122 * Added nmem_init and nmem_exit to initialize and release
1123 NMEM resources. Function nmem_init should be called once in the
1124 initial thread before NMEM/ODR is used. statserv.c and client.c
1125 have been changed accordingly. The change was necessary to make
1126 NMEM thread safe. The NMEM memory pool is shared amongst threads
1127 in a process. Unix-based applications will still work fine without
1130 Added NT Services interface for the the Z39.50 (statserv) Server.
1131 Refer to the ztest.c source on the usage.
1133 Windows 95/NT port using MSVC5.0. Project files are included in the
1136 * Defined new 'global' handle for the retrieval (data1) system. The
1137 new handled, data1_handle, describes the state of the data1 system.
1138 This handle is passed as first argument to virtually all
1139 data1 related routines. The functions data1_create and data1_destroy
1140 creates and destroys a data1 handle respectively.
1142 Added ODR encode stream member to all backend request structures
1143 init, search, scan etc. This stream should be used to allocate all
1144 memory used for the response when thread safe operation is needed.
1146 Changed the comstack utility, cs_addstr, to be thread safe. The
1147 returned hostname string returned by the function is now part the
1150 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1151 function. The cs_straddr takes a COMSTACK handle as argument, so this
1152 function must be used after cs_create and before bind/connect.
1153 This function is thread safe.
1155 Moved test server to 'ztest' directory - generic server code still
1156 in 'server' directory.
1158 Made prefix query (pquery.c) utility thread safe.
1160 Added new function modifier YAZ_EXPORT to 'export' public DLL
1161 functions when using windows (see include/yconfig.h).
1163 Added definitions to the OID database (util/oid.c) (RVDM).
1165 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1167 Added call to ccl_rpn_delete in client program.
1169 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1170 release of RPN structure.
1172 Added support for C++, headers uses extern "C" for public definitions.
1173 With input from RVDM.
1175 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1176 Thanks to Ronald van der Meer (RVDM).
1178 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1180 Added support for private extensions to the OID database
1181 (oid_setprivateoids()). Thanks to RVDM.
1183 Added optional, physical ANY (key replication)
1185 Fixed null-reference problem in GRS-1 output filter.
1187 Proximity operator added to Prefix Query Format (PQF).
1189 In test client command "base" accepts multiple databases.
1191 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1195 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1197 Smallish bug-fixes in the new encoders/decoders (explain).
1199 Bug fixed in DeleteRequest.
1201 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1203 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1205 Added SOIF syntax (using private OID for now) to retrieval module and client.
1207 Added Update extended service.
1209 Added SearchResult-1 additional info structure.
1211 Added optional CCL (ISO8777) interpreter as separate module. Available
1214 --- 1.2 1996/6/10 (1st anniversary release)
1216 Added Summary record syntax. Lightly tested.
1218 Added OPAC record syntax. Untested.
1220 Added ResourceReport service encoders/decoders. Untested.
1222 Fixed bug in z_Unit - wrong tagging on unitSystem.
1224 Fixed bug in the DiagRecs decoder.
1226 Added options for max PDU size and session timeout to frontend-server.
1228 Added documentation of query-language parsers and other supporting utilities.
1230 [frontend-server] Added Attribute set to the bend_scanrequest API.
1232 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1233 surrogate diagnostics were generated.
1235 [retrieval] Allow multiple local values for attribute.
1237 [retrieval] Allow multiple attributes per element in .abs files. index type.
1239 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1241 --- 1.1pl2 1996/4/10
1243 Minor changes, mostly specific to Zebra's requirements (retrieval)
1247 Repaired bug in frontend server when running multiple listening
1248 endpoints in dynamic mode.
1250 z_External() now won't break if a known, ASN.1 value comes encapsulated
1251 in an octet-string. The value will pass through unmodified in an Odr_oct.
1253 Added a bit of code to the demo client to decode & display
1254 ASN.1-structured records represented in the octet-aligned branch of
1255 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1257 Added z_ext_getentbyref() to the ASN module. Doc updated.
1259 * Completed the SCAN definition in the ASN module. This may break SCAN
1260 code based on older YAZ-versions at compile-time. The fix is easy -
1263 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1264 under the SCAN definition. Remember to initialize this, server-people.
1266 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1267 that this does not extend to ODR and ASN.
1269 Comstack allows insertion of established socket (primarily for
1270 inetd-operation of servers). Doc updated.
1272 Front-end server can now start from the inetd in TCP mode. Doc
1275 --- 1.0pl4 1996/1/24
1279 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1280 the rank and record number.
1282 Adjustments to the frontend server.
1284 Fixed diagnostic BER dumper. It ignored the file argument.
1288 Various changes to retrieval module.
1290 Changed the union discriminators of the protocol files from enums to
1291 ints paired with #defines.
1293 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1296 *Changed operator in the RPN structure to 'roperator', again to avoid a
1299 Fixed problems in Explain decoders/encoders.
1301 --- 1.0pl2 1995/12/6
1303 Memory bug in log module fixed.
1305 --- 1.0pl1 1995/12/5
1307 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1309 Bug in Explain DatabaseInfo module fixed.
1311 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1315 The shift to v1.0 signals that we now consider the *core* functionality
1316 of YAZ reasonably stable (the core being more or less equivalent to
1317 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1318 tested (Explain not at all - though that will happen soonish).
1320 Minor changes to code to support Windows port.
1322 Various minor changes after we're getting to use GRS-1 & co. more.
1324 Added Espec-1 format.
1326 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1327 of the protocol and it cannot be selected when encoding (maps into 'string'
1328 when decoding). Needed to talk to some servers.
1330 Demo client can request simple element set names.
1332 Added Diagnostic Format encoders/decoders.
1334 Added simple Close handling to frontend server (no hooks for resource
1335 reporting yet), and demonstration client.
1337 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1339 --- 1.0b3 1995/08/24
1341 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1342 handled incorrectly when records were requested in the searchResponse. This
1343 will only affect you if you use the frontend-server.
1345 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1346 Test-client will ask for and print GRS1. Ztest will return dummy records
1349 Added Explain encoders/decoders to the service-level API. Untested.
1351 Added Extended Services: Item Order encoders and decoders to the Service-
1352 level API. Untested. We could use a recent copy of the pertinent bits
1353 of the ILL protocol to add those bits.
1355 Added diagnostic format 1 encoders/decoders to the service-level API.
1358 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1359 odr_cons.c, which causes a more correct output.
1361 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1362 was always set to 0 when no records were requested in the searchRequest.
1364 * Added better external-handling. This shouldn't harm old code that
1365 *encodes* externals. It can break code that looks for a
1366 'single-ASN1-type' representation, since those types that are known
1367 are now decoded immediately. Look at the SUTRS sample code in
1368 seshigh.c and client.c. Documentation updated.
1370 Handling of structured records in bend_fetchresponse. Length -1 marks
1371 structured record, type is deduced from format field.
1373 --- 1.0b2 1995/06/27
1374 Fairly quick maintenance release to add SUTRS support.
1376 Fixed handling of SUTRS records in the demonstration client.
1378 * Added format field to the bend_fetchrequest and bend_fetchresponce
1379 structures of the backend API (frontend server). When the record is
1380 returned, the value of the format field is mapped to an OID. The
1381 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1382 of the record. The special value VAL_NONE in the bend_request means
1383 that no specific format was requested by the client. Documentation
1384 updated accordingly. Test server (ztest) will return a fixed dummy
1385 SUTRS record if your client requests SUTRS.
1387 Documentation updated accordingly.
1389 You can now set external libraries and RANLIB support in the top-level
1393 First public release.
