5 Fix memory leaks in MARC record handling for ZOOM.
7 More fixes for scan. Non-zero stepSize handled. OID's fixes.
9 Prefix query parser reports "fail" when bad attribute set is given.
11 Fix in MARC decoder. Proximity logging. Fix for attribute set
12 in scan handler for server. Patches by Shigeru Ishida.
14 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
17 Configure option --with-openssl=<dir> now works when a directory is
18 specified. Patch provided by Morten Bøgeskov.
20 New option for YAZ client, -u <auth>, that sets authentication.
22 ZOOM fix: error information only cleared for Bib-diagnostics (not
23 fatal errors, like connection failed, etc).
25 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
29 Scan for ZOOM API. New object ZOOM_scanset. New functions
30 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
33 New ZOOM function, ZOOM_connection_last_event, that returns type
34 of last event (such as "receive data", "send data", "apdu received",
37 New ZOOM option, schema, that specifies shema OID for retrieval.
39 New CCL feature. Qualifiers can be aliases for one or more
40 other qualifiers (if more than one is given, OR is used).
42 ZOOM uses named result sets if target supports it.
44 Two new YAZ client commands: . (dot, which sources a script of YAZ
45 client commands), and ! (to execute shell command.). Implemented
48 Working on Debian packages.
52 YAZ client enables named result sets only if target supports it.
54 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
56 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
57 with key="host" to get same result.
59 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
60 Function Z3950_resultset_record(s) returns references to records
61 "owned" by resultset. To become owner use Z3950_record_clone.
63 Function z_ext_record handles Extended Services. Thanks to
68 CCL Parser fix: ignore token comma when dealing with and-lists.
70 Documentation updates for COMSTACK.
72 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
73 Changed prototype Z3950_records. For some functions, int parameters
74 were changed to size_t.
76 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
79 New MARC decode/display function, marc_display_exl, which properly rejects
80 non-ISO2709 records. YAZ client uses it.
84 Fix bug: local attribute set wasn't set correctly in PQF strings.
88 * Old Z39.50 codecs no longer supported.
90 Added ZOOM C binding. See http://zoom.z3950.org/
92 Renamed states for COMSTACKs to avoid confusion with events.
94 Implemented cs_look and proper cs_rcvconnect.
96 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
98 Configure detects POSIX threads on OpenBSD.
100 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
101 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
103 When error is returned from present handler, non-surrogate diagnostic
104 is returned in present response (and fetch handler is no longer called).
106 * Minor adjustments to pquery parser (PQF). Token characters may be
107 escaped by using backslash (C-style).
109 PQF parser allows string attribute values to be specified. For @attr,
110 non-numeric characters after the equal-sign are treated as strings
111 (e.g. @attr 9=title).
113 CCL trunction character may be defined (@truncation in file)
115 * function zget_ExtendedServicesRequest sets waitAction to
116 waitIfPossible (was wait).
118 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
121 CCL operator names may be set in field definition files (CCL_bibset).
122 See ccl/bib1 for an example.
124 Fixes in ASN.1 compiler for C++ compatibility.
126 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
127 and "op_or" to avoid conflict with C++.
129 Fixed problem with GNU readline detection on Redhat 7.0.
131 Added step-size for Scan backend handler.
133 Fixed bug that made the frontend server crash when no attribute
134 set was specified for scan.
136 Front-end server automatically switches to original working directory
137 when installed as an NT service. Previously -w had to be specified to
140 Added extended attributes for retrieval module (data1), so that data1
141 records carry d1_readXML/SGML attributes. d1_read also supports
142 null-data rules ( <tag/>)
144 On UNIX when POSIX threads are available, a separate library libyazthread
145 is created. Programmers should link with that library and the yaz library
146 when using threads. The reason for the split was that some applications
147 on Linux, such as Apache, doesn't work well when using shared objects that
150 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
151 (or any frontend server) in SSL mode by specifying ssl: followed by
152 address. Only tested on UNIX.
154 Added feature for CCL module. Virtual structure s=al or s=ol generates
155 and-list and or-list respectively instead of phrase search.
159 * Added prefix "yaz_" for the functions log_init.., log_file.. and
160 log_mask_str. This was done to avoid name conflicts with other libraries
161 (such as other PHP extensions).
163 Added raw OID member for preferred record syntax (request_format_raw)
164 and returned record syntax (output_format_raw) for backend fetch method.
166 Config file yaz-config now accepts options so that it returns specific
167 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
169 Shared library support for UNIX using GNU libtool.
171 * Modified backend interface. Request/Response struct's replaced by
172 one read/write C struct. For example bend_fetchrequest and
173 bend_fetchresult have been replaced by single bend_fetch_rr struct.
174 Every handler - even search has to be registered in bend_init
175 handler. This means that the YAZ library no longer refers to
176 external functions and it makes it possible to make the whole
177 thing a single DLL/SO.
179 Added Segment handler for backend server.
181 Added Zmbol/Zebra administrative functions to YAZ client.
183 Threaded frontend server on UNIX (when POSIX Threads are available).
184 Starting the server with option -T enables multi-threading.
188 Added configure option --enable-comp/disable-comp to control use
189 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
190 located in sub directory asn.
192 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
193 in ${exec_prefix}/bin along with the other programs yaz-client and
196 GNU automake used to maintain makefiles.
200 Changed retrieval module so that we can load records with no abstract
201 syntax defined. Tagpaths in these records are fully composed of string
204 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
208 On UNIX, the generated makefile now supports a proper 'make install'.
209 The prefix can be set via GNU configure to set the install location
210 (default is /usr/local).
212 * YAZ programs client and ztest were renamed to yaz-client and
213 yaz-ztest to avoid conflicts when users install YAZ in "standard"
214 locations, such as /usr/bin,/usr/local/bin,etc.
216 * YAZ Header files were moved from include to include/yaz. YAZ Header
217 files are referred to as include <yaz/log.h> rather than <log.h>.
218 The YAZ include path (-I ..) is therefore the same as before. Programmers
219 should update their #include statements or use -Ipath/include/yaz
220 instead. The main motivation for doing this change is that YAZ header files
221 can be installed in "standard" locations /usr/include,/usr/local/include
222 without introducing conflicts, since ALL YAZ header files are stored
223 in subdirectory yaz (under /usr/include for example).
225 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
226 rather than project/workspace files. We switched because project files
227 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
230 Changed name of logging function, logf, to yaz_log, to prevent name
231 clash with some math-log functions. The YAZ header log.h defines logf
232 to yaz_log (#define) so there should be no incompatibilities by this
235 Added bend_start/bend_stop handlers for server. These handler are
236 called on start/stop of server. For windows they are called whenever
237 a service is started/stopped.
239 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
240 a fairly small ASN.1 compiler written in Tcl. The compiler is located
241 in util/yc.tcl. The auto-generated C code structures are, in a few
242 cases, incompatible with the old decoders. There are differences in the
243 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
244 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
245 The preprocessor variable ASN_COMPILED is defined when the compiled
246 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
247 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
248 wish to use the old encoders/decoders you can specify --disable-yc
251 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
252 version so that it supports both new - and old version of DB Update
254 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
255 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
256 change. The name parameter can be set to 0 in which no name is specified
257 for the construction. The macros odr_implicit and odr_explicit sets name
258 parameter to zero for the construction involved. New macros
259 odr_implicit_tag and odr_explicit_tag are similar to the others,
260 except that a name parameter is added. For programmers' that don't use
261 ODR they probably only need to change the call to z_APDU and z_External.
263 Added access control facility by interfacing the TCP wrapper library.
264 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
265 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
266 name of the daemon and enables the access control as specified in
267 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
269 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
270 den Dool <H.M.vdnDool@kub.nl>.
272 Added reference ID parameter to most functions in server API - refer
273 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
275 Changed name of ccl library to libccl.a (was ccl.a).
277 Fixed bug in decoder for Explain (Category TargetInfo).
279 Added support for GNU readline in client. Thanks to Jacob Poulsen
280 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
282 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
283 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
284 IMPLEMENTATION! This change was made to the development version before
285 the ZIG decided to retract the amendment. If any users MUST be
286 compatible with the original Update definition, PLEASE CONTACT US, and
287 we will include a separate definition corresponding to the old Update
288 ES. Note that because of the change to the ASN.1 of the
289 TaskPackageRecordStructure we cannot define a single structure that
290 will support both versions.
292 * Added const modifier to buffer parameter for some ODR/BER encoding
293 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
294 completeWAIS, odr_dumpBER.
296 Fixed bug in client.c which caused a crash when a scanResponse didn't
297 contain positionOfTerm.
299 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
300 * will cause an error in a client if a non-YAZ target sends both a
301 * list of Scan entries and non-surrogate diagnostics.
303 Retrieval module enhancements. Tag sets may be typed in the reference
304 to it. From the .abs-file the "tagset" directive takes a third optional
305 integer type for the tag set referenced. From a .tag-file the "include"
306 directive takes a third optional type as well. The old "type" directive
307 in the tag set itself is still recognized but acts as the default type
310 Backend interface change. Individual Scan terms returned from bend_scan
311 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
312 in include/backend.h.
314 Retrieval module enhancements. Multiple tag sets and attribute sets may
315 be specified in abstract syntax specs. Revised the error/warning for
316 logging messages reported by the retrieval module when reading the
319 Object Identifier system (oid_..) changed. The API is backwards
320 compatible but the oid-routines now allocates new OID's when needed.
321 Raw OID's may be specified in oid_getvalbyname.
323 YAZ now uses GNU configure to generate Makefile(s).
325 * Minor changes in some of the member names of DeleteResultSetRequest and
326 DeleteResultSetResponse. See include/proto.h.
328 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
329 and added member 'languages' in TargetInfo (which was missing).
331 Changed the way attribute sets are handled in the retrieval
332 module. These are now cached, just like the abstract syntaxes
335 Changed YAZ so that it links with compiled ASN.1.
337 Added Explain-schema definitions and mapping routines. The following
338 Explain categories have been implemented: AttributeDetails,
339 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
341 Fixed minor bug in Windows version of Server Library.
343 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
345 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
347 Added EXTERNAL: UNIverse Resource Report (non-standard).
349 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
350 ENUMERATED and SET OF.
352 * Added 'const' to some of the char pointer arguments for the
353 functions, data1_read_node, data1_getelementbytagname,
354 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
357 Fixed bug in data1_insert_taggeddata - the last_child member of
358 parent wasn't initialised.
360 * Changed data1_read_record and data1_read_node so that the supplied
361 "SGML"-buffer is read-only. In particular the resulting data1 - tree
362 doesn't refer to any parts of the "SGML"-buffer.
364 Fixed bug in server library (Windows version of statserv_remove).
366 * Changed code so that it compiles as C++. The type definition
367 of Odr_fun which is a member of Odr_arm was changed. The result is,
368 that an explicit typecast is needed for the fun pointer when
369 using Odr_arm - as in:
370 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
372 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
374 Implemented the new structured date and time definition as approved
375 by the ZIG. Added schemaId element to the specificTag in Espec-1
376 (also approved at the last ZIG). Thanks to RVDM.
378 Added some Object identifiers (RVDM).
380 Changed the Update Extended Service (RVDM).
382 Added command "refid" to client which specifies referenceId for
383 the following requests.
385 Implemented extended service handling for server. See ztest.c
386 for an example as well as backend.h. New handlers are registerd
389 * Changed interface for sort in server.
391 Added new members to statserv_options_block. It allows a server
392 to read options from another source than just the command line. Thanks
393 to Charles Woodfield.
395 * Changed definition of Z_Triple in file prt-grs.h - member boolean
396 renamed to zboolean. Some C++ compilers complained about the name.
398 Minor changes to gils.abs. Added index 's' (sort) on title
399 and date/time-last-modified.
403 Fixed bug in server library regarding inetd mode (-i). This bug
404 was introduced by release 1.4.
408 Added sort facility in client and backend server interface.
410 Fixed problem with dependencies in Makefile(s).
412 Fixed bugs for encoders/decoders of extended services and
415 Implemented sub-tree feature for schemas. Sub-trees are
416 referenced in *.abs-files. See explain.abs for an example
417 of the use of this feature.
419 Modified bib1.att; local attributes for ANY didn't include
420 ANY itself (only affects use of the retrieval module).
422 Fixed bug in plain SGML reader in function data1_read_node:
423 tags with prefix "var" was incorrectly interpreted as variants.
425 Added feature "sub-schemas" to enable references to - and definitions
426 of - group of elements.
428 * Removed member parent from type data1_element (in data1.h).
430 Implemented function odr_nullval() that returns the value of
433 * Removed member num_children from data1_node (in data1.h).
435 Made NT service interface part of the server library. The
436 function statserv_main uses the NT service when required and
437 calls the statserv_start / statserv_close routines.
439 Routine zget_SearchRequest and zget_PresentRequest fills
440 resultSetName/Id member with "default" instead of "Default".
442 Fixed memory leak in server. Request queue member wasn't freed.
444 Fixed nmem_exit so that memory is freed.
448 Revised the CCL parser utility to be thread safe.
450 Added function, oid_ent_to_oid, to replace the function
451 oid_getoidbyent, which is not thread safe.
453 * Added nmem_init and nmem_exit to initialize and release
454 NMEM resources. Function nmem_init should be called once in the
455 initial thread before NMEM/ODR is used. statserv.c and client.c
456 have been changed accordingly. The change was necessary to make
457 NMEM thread safe. The NMEM memory pool is shared amongst threads
458 in a process. Unix-based applications will still work fine without
461 Added NT Services interface for the the Z39.50 (statserv) Server.
462 Refer to the ztest.c source on the usage.
464 Windows 95/NT port using MSVC5.0. Project files are included in the
467 * Defined new 'global' handle for the retrieval (data1) system. The
468 new handled, data1_handle, describes the state of the data1 system.
469 This handle is passed as first argument to virtually all
470 data1 related routines. The functions data1_create and data1_destroy
471 creates and destroys a data1 handle respectively.
473 Added ODR encode stream member to all backend request structures
474 init, search, scan etc. This stream should be used to allocate all
475 memory used for the response when thread safe operation is needed.
477 Changed the comstack utility, cs_addstr, to be thread safe. The
478 returned hostname string returned by the function is now part the
481 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
482 function. The cs_straddr takes a COMSTACK handle as argument, so this
483 function must be used after cs_create and before bind/connect.
484 This function is thread safe.
486 Moved test server to 'ztest' directory - generic server code still
487 in 'server' directory.
489 Made prefix query (pquery.c) utility thread safe.
491 Added new function modifier YAZ_EXPORT to 'export' public DLL
492 functions when using windows (see include/yconfig.h).
494 Added definitions to the OID database (util/oid.c) (RVDM).
496 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
498 Added call to ccl_rpn_delete in client program.
500 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
501 release of RPN structure.
503 Added support for C++, headers uses extern "C" for public definitions.
504 With input from RVDM.
506 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
507 Thanks to Ronald van der Meer (RVDM).
509 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
511 Added support for private extensions to the OID database
512 (oid_setprivateoids()). Thanks to RVDM.
514 Added optional, physical ANY (key replication)
516 Fixed null-reference problem in GRS-1 output filter.
518 Proximity operator added to Prefix Query Format (PQF).
520 In test client command "base" accepts multiple databases.
522 Fixed bug in cs_close stack that caused trouble with WINSOCK.
526 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
528 Smallish bug-fixes in the new encoders/decoders (explain).
530 Bug fixed in DeleteRequest.
532 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
534 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
536 Added SOIF syntax (using private OID for now) to retrieval module and client.
538 Added Update extended service.
540 Added SearchResult-1 additional info structure.
542 Added optional CCL (ISO8777) interpreter as separate module. Available
545 --- 1.2 1996/6/10 (1st anniversary release)
547 Added Summary record syntax. Lightly tested.
549 Added OPAC record syntax. Untested.
551 Added ResourceReport service encoders/decoders. Untested.
553 Fixed bug in z_Unit - wrong tagging on unitSystem.
555 Fixed bug in the DiagRecs decoder.
557 Added options for max PDU size and session timeout to frontend-server.
559 Added documentation of query-language parsers and other supporting utilities.
561 [frontend-server] Added Attribute set to the bend_scanrequest API.
563 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
564 surrogate diagnostics were generated.
566 [retrieval] Allow multiple local values for attribute.
568 [retrieval] Allow multiple attributes per element in .abs files. index type.
570 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
574 Minor changes, mostly specific to Zebra's requirements (retrieval)
578 Repaired bug in frontend server when running multiple listening
579 endpoints in dynamic mode.
581 z_External() now won't break if a known, ASN.1 value comes encapsulated
582 in an octet-string. The value will pass through unmodified in an Odr_oct.
584 Added a bit of code to the demo client to decode & display
585 ASN.1-structured records represented in the octet-aligned branch of
586 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
588 Added z_ext_getentbyref() to the ASN module. Doc updated.
590 * Completed the SCAN definition in the ASN module. This may break SCAN
591 code based on older YAZ-versions at compile-time. The fix is easy -
594 * Added 'displayTerm' and OtherInformation to the TermInfo structure
595 under the SCAN definition. Remember to initialize this, server-people.
597 Comstack should now support the WAIS protocol in TCP/IP mode. Note
598 that this does not extend to ODR and ASN.
600 Comstack allows insertion of established socket (primarily for
601 inetd-operation of servers). Doc updated.
603 Front-end server can now start from the inetd in TCP mode. Doc
610 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
611 the rank and record number.
613 Adjustments to the frontend server.
615 Fixed diagnostic BER dumper. It ignored the file argument.
619 Various changes to retrieval module.
621 Changed the union discriminators of the protocol files from enums to
622 ints paired with #defines.
624 *Changed oident.class to oident.oclass to avoid a reserved word in C++
627 *Changed operator in the RPN structure to 'roperator', again to avoid a
630 Fixed problems in Explain decoders/encoders.
634 Memory bug in log module fixed.
638 Occasional malloc() of 0 bytes fixed in d1_espec.c.
640 Bug in Explain DatabaseInfo module fixed.
642 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
646 The shift to v1.0 signals that we now consider the *core* functionality
647 of YAZ reasonably stable (the core being more or less equivalent to
648 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
649 tested (Explain not at all - though that will happen soonish).
651 Minor changes to code to support Windows port.
653 Various minor changes after we're getting to use GRS-1 & co. more.
655 Added Espec-1 format.
657 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
658 of the protocol and it cannot be selected when encoding (maps into 'string'
659 when decoding). Needed to talk to some servers.
661 Demo client can request simple element set names.
663 Added Diagnostic Format encoders/decoders.
665 Added simple Close handling to frontend server (no hooks for resource
666 reporting yet), and demonstration client.
668 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
672 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
673 handled incorrectly when records were requested in the searchResponse. This
674 will only affect you if you use the frontend-server.
676 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
677 Test-client will ask for and print GRS1. Ztest will return dummy records
680 Added Explain encoders/decoders to the service-level API. Untested.
682 Added Extended Services: Item Order encoders and decoders to the Service-
683 level API. Untested. We could use a recent copy of the pertinent bits
684 of the ILL protocol to add those bits.
686 Added diagnostic format 1 encoders/decoders to the service-level API.
689 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
690 odr_cons.c, which causes a more correct output.
692 Fixed handling of searchRequest in frontend server. NextResultSetPosition
693 was always set to 0 when no records were requested in the searchRequest.
695 * Added better external-handling. This shouldn't harm old code that
696 *encodes* externals. It can break code that looks for a
697 'single-ASN1-type' representation, since those types that are known
698 are now decoded immediately. Look at the SUTRS sample code in
699 seshigh.c and client.c. Documentation updated.
701 Handling of structured records in bend_fetchresponse. Length -1 marks
702 structured record, type is deduced from format field.
705 Fairly quick maintenance release to add SUTRS support.
707 Fixed handling of SUTRS records in the demonstration client.
709 * Added format field to the bend_fetchrequest and bend_fetchresponce
710 structures of the backend API (frontend server). When the record is
711 returned, the value of the format field is mapped to an OID. The
712 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
713 of the record. The special value VAL_NONE in the bend_request means
714 that no specific format was requested by the client. Documentation
715 updated accordingly. Test server (ztest) will return a fixed dummy
716 SUTRS record if your client requests SUTRS.
718 Documentation updated accordingly.
720 You can now set external libraries and RANLIB support in the top-level
724 First public release.
