1 Possible compatibility problems with earlier versions marked with '*'.
5 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
6 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
7 distance=n, order=true/false, relation=le, prox unit=word. If
8 n is omitted, distance 1 is used.
10 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
11 on Solaris. Patch from Ko van der Sloot.
13 New MARC decode API. All new functions operate on a yaz_marc_t
14 handle. The most important new functions are: yaz_marc_create,
15 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
16 decode and destroy respectively. Decoder can produce formats
17 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
18 include/yaz/marcdisp.h.
20 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
21 to UTF-8, UCS-32, wchar_t or Latin-1.
23 * Prototypes for yaz_iconv_-functions moved to separate header
24 include/yaz/yaz-iconv.h.
26 Make a few private functions 'static' in unix.c. This prevents
27 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
29 For ZOOM connection, the options targetImplementation{Id,Name,Version}
30 are set when Init Response is received.
32 New function ZOOM_connection_error_x similar to ZOOM_connection_error
33 but returns diagnostic set as well.
35 New function yaz_strerror which is a portable wrapper for
36 strerror/strerror_r/GetLastMessage.
38 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
39 is returned for MARC. If type is "oai", then OAI MARC is returned.
41 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
46 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
48 Fix bad race conditions on SIGTERM and terminate gracefully in
51 Move retrieval (data1) module to Zebra since nobody seems to be
54 Add GRS-1 render for ZOOM using same format as yaz-client.
58 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
60 Fix broken ESpec handling in data1 module.
62 SGML reader parses comments and makes them part of the data1 tree.
64 Added several type casts so that YAZ compiles as C++ code.
66 ZOOM didn't handle PDU encoding failures properly.
68 Added more Bib-1 diagnostics (approved extensions).
70 GNU configure: better check for iconv.
72 More portable use of accept, getpeername. Check for socklen_t. Use
73 int/size_t if socklen_t is not defined.
77 PQF parser rejects bad queries - including those with extra
78 characters in them. PQF parser used to silently ignore that.
79 Cleaner API for PQF added, which allows you to get detailed
80 error information for bad queries (see yaz/pquery.h).
82 Fixed bug in ZOOM_record_get for type "database".
84 Implemented mini iconv library supporting conversions between
85 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
87 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
91 Fixed ZOOM C record cache so that preferredRecordSyntax and
92 elementSetName is used to check for already fetched records.
96 Added three members in bend_initrequest structure to facilitate
97 character set negotiation.
99 Fixed a bug in frontend server that could cause indefinite
100 loops under rare conditions.
102 Revised character set utilities (charneg.h) so that encoding
103 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
105 For PQF, directive @term <type> sets term type for Scan/Search.
106 Here <type> is general, string, numeric, null. The term type
107 is inherited - just like @attr.
109 New call odr_set_charset that sets character set conversion for
110 international-strings on a ODR stream. Prototype is:
111 int odr_set_charset(ODR o, const char *to, const char *from);
112 The InternationalString is still represented as C string in YAZ
113 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
114 won't). On the protocol level, you can use any encoding.
116 Support for UNIX sockets in ZOOM.
118 Solaris recv sometimes returns errno == ENOENT. It is treated as
119 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
121 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
122 both client and server. Code by Morten Bøgeskov.
126 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
127 that they can be used directly from Visual Basic. You must recompile
128 your windows APP if you're using ZOOM.
130 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
131 Commands "lang" and "charset" sets language and character set respectively.
132 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
133 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
135 Attributes from multiple CCL fields may be OR'ed rather than merged
136 using directive "@field or". Fields are still merged by default -
137 equivalent to "@field merge".
139 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
142 Fixed bug in zget for parameter ExtendedServicesResponse.
148 Added PQF feature: '@attr type=value' may be written as '@type=value'.
150 Client displays USR.1:SearchResult-1 (hits per term).
152 Additional Search Info for search in Generic Frontend Server.
154 Fixed CCL parsing of "field=s".
156 WIN32 installer - using the excellent NSIS software from nullsoft.
158 Fixed CCL parsing of "field = - <number>".
160 Added function yaz_marc_decode that decodes MARC for line mode
161 display or XML (similar to that used by JZKit).
163 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
164 Z39.50. But ISO/ILL was, however.
166 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
167 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

174 New YAZ client features: Command completion and new commands:
175 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
176 Code provided by Jacob Poulsen.
178 New call oid_trav, that visits all registered OIDs via callback.
180 Function ZOOM_record_get now returns const char pointer rather than
181 void pointer. It saves a lot of type casts.
183 For YAZ client, command "auth" now allows you to set authentication
184 in IdPass style. It is enabled when three tokens are given - order
185 is user, group and password.
187 Fix memory leaks in MARC record handling for ZOOM.
189 New option for YAZ client, -k <kilobytes> that sets
190 maximum record size. Similar to -k option for generic frontend
191 server and yaz-ztest.
193 More fixes for scan. Non-zero stepSize handled. OID's fixes.
195 Prefix query parser reports "fail" when bad attribute set is given.
197 Fix in MARC decoder. Proximity logging. Fix for attribute set
198 in scan handler for server. Patches by Shigeru Ishida.
200 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
203 Configure option --with-openssl=<dir> now works when a directory is
204 specified. Patch provided by Morten Bøgeskov.
206 New option for YAZ client, -u <auth>, that sets authentication.
208 ZOOM fix: error information was sometimes "missing", since error
209 was cleared/reset too when it shouldn't.
211 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
215 Scan for ZOOM API. New object ZOOM_scanset. New functions
216 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
217 ZOOM_scanset_destroy.
219 New ZOOM function, ZOOM_connection_last_event, that returns type
220 of last event (such as "receive data", "send data", "apdu received",
223 New ZOOM option, schema, that specifies shema OID for retrieval.
225 New CCL feature. Qualifiers can be aliases for one or more
226 other qualifiers (if more than one is given, OR is used).
228 ZOOM uses named result sets if target supports it.
230 Two new YAZ client commands: . (dot, which sources a script of YAZ
231 client commands), and ! (to execute shell command.). Implemented
234 Working on Debian packages.
238 YAZ client enables named result sets only if target supports it.
240 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
242 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
243 with key="host" to get same result.
245 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
246 Function Z3950_resultset_record(s) returns references to records
247 "owned" by resultset. To become owner use Z3950_record_clone.
249 Function z_ext_record handles Extended Services. Thanks to
254 CCL Parser fix: ignore token comma when dealing with and-lists.
256 Documentation updates for COMSTACK.
258 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
259 Changed prototype Z3950_records. For some functions, int parameters
260 were changed to size_t.
262 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
265 New MARC decode/display function, marc_display_exl, which properly rejects
266 non-ISO2709 records. YAZ client uses it.
270 Fix bug: local attribute set wasn't set correctly in PQF strings.
274 * Old Z39.50 codecs no longer supported.
276 Added ZOOM C binding. See http://zoom.z3950.org/
278 Renamed states for COMSTACKs to avoid confusion with events.
280 Implemented cs_look and proper cs_rcvconnect.
282 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
284 Configure detects POSIX threads on OpenBSD.
286 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
287 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
289 When error is returned from present handler, non-surrogate diagnostic
290 is returned in present response (and fetch handler is no longer called).
292 * Minor adjustments to pquery parser (PQF). Token characters may be
293 escaped by using backslash (C-style).
295 PQF parser allows string attribute values to be specified. For @attr,
296 non-numeric characters after the equal-sign are treated as strings
297 (e.g. @attr 9=title).
299 CCL trunction character may be defined (@truncation in file)
301 * function zget_ExtendedServicesRequest sets waitAction to
302 waitIfPossible (was wait).
304 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
307 CCL operator names may be set in field definition files (CCL_bibset).
308 See ccl/bib1 for an example.
310 Fixes in ASN.1 compiler for C++ compatibility.
312 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
313 and "op_or" to avoid conflict with C++.
315 Fixed problem with GNU readline detection on Redhat 7.0.
317 Added step-size for Scan backend handler.
319 Fixed bug that made the frontend server crash when no attribute
320 set was specified for scan.
322 Front-end server automatically switches to original working directory
323 when installed as an NT service. Previously -w had to be specified to
326 Added extended attributes for retrieval module (data1), so that data1
327 records carry d1_readXML/SGML attributes. d1_read also supports
328 null-data rules ( <tag/>)
330 On UNIX when POSIX threads are available, a separate library libyazthread
331 is created. Programmers should link with that library and the yaz library
332 when using threads. The reason for the split was that some applications
333 on Linux, such as Apache, doesn't work well when using shared objects that
336 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
337 (or any frontend server) in SSL mode by specifying ssl: followed by
338 address. Only tested on UNIX.
340 Added feature for CCL module. Virtual structure s=al or s=ol generates
341 and-list and or-list respectively instead of phrase search.
345 * Added prefix "yaz_" for the functions log_init.., log_file.. and
346 log_mask_str. This was done to avoid name conflicts with other libraries
347 (such as other PHP extensions).
349 Added raw OID member for preferred record syntax (request_format_raw)
350 and returned record syntax (output_format_raw) for backend fetch method.
352 Config file yaz-config now accepts options so that it returns specific
353 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
355 Shared library support for UNIX using GNU libtool.
357 * Modified backend interface. Request/Response struct's replaced by
358 one read/write C struct. For example bend_fetchrequest and
359 bend_fetchresult have been replaced by single bend_fetch_rr struct.
360 Every handler - even search has to be registered in bend_init
361 handler. This means that the YAZ library no longer refers to
362 external functions and it makes it possible to make the whole
363 thing a single DLL/SO.
365 Added Segment handler for backend server.
367 Added Zmbol/Zebra administrative functions to YAZ client.
369 Threaded frontend server on UNIX (when POSIX Threads are available).
370 Starting the server with option -T enables multi-threading.
374 Added configure option --enable-comp/disable-comp to control use
375 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
376 located in sub directory asn.
378 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
379 in ${exec_prefix}/bin along with the other programs yaz-client and
382 GNU automake used to maintain makefiles.
386 Changed retrieval module so that we can load records with no abstract
387 syntax defined. Tagpaths in these records are fully composed of string
390 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
394 On UNIX, the generated makefile now supports a proper 'make install'.
395 The prefix can be set via GNU configure to set the install location
396 (default is /usr/local).
398 * YAZ programs client and ztest were renamed to yaz-client and
399 yaz-ztest to avoid conflicts when users install YAZ in "standard"
400 locations, such as /usr/bin,/usr/local/bin,etc.
402 * YAZ Header files were moved from include to include/yaz. YAZ Header
403 files are referred to as include <yaz/log.h> rather than <log.h>.
404 The YAZ include path (-I ..) is therefore the same as before. Programmers
405 should update their #include statements or use -Ipath/include/yaz
406 instead. The main motivation for doing this change is that YAZ header files
407 can be installed in "standard" locations /usr/include,/usr/local/include
408 without introducing conflicts, since ALL YAZ header files are stored
409 in subdirectory yaz (under /usr/include for example).
411 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
412 rather than project/workspace files. We switched because project files
413 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
416 Changed name of logging function, logf, to yaz_log, to prevent name
417 clash with some math-log functions. The YAZ header log.h defines logf
418 to yaz_log (#define) so there should be no incompatibilities by this
421 Added bend_start/bend_stop handlers for server. These handler are
422 called on start/stop of server. For windows they are called whenever
423 a service is started/stopped.
425 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
426 a fairly small ASN.1 compiler written in Tcl. The compiler is located
427 in util/yc.tcl. The auto-generated C code structures are, in a few
428 cases, incompatible with the old decoders. There are differences in the
429 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
430 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
431 The preprocessor variable ASN_COMPILED is defined when the compiled
432 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
433 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
434 wish to use the old encoders/decoders you can specify --disable-yc
437 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
438 version so that it supports both new - and old version of DB Update
440 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
441 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
442 change. The name parameter can be set to 0 in which no name is specified
443 for the construction. The macros odr_implicit and odr_explicit sets name
444 parameter to zero for the construction involved. New macros
445 odr_implicit_tag and odr_explicit_tag are similar to the others,
446 except that a name parameter is added. For programmers' that don't use
447 ODR they probably only need to change the call to z_APDU and z_External.
449 Added access control facility by interfacing the TCP wrapper library.
450 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
451 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
452 name of the daemon and enables the access control as specified in
453 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
455 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
456 den Dool <H.M.vdnDool@kub.nl>.
458 Added reference ID parameter to most functions in server API - refer
459 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
461 Changed name of ccl library to libccl.a (was ccl.a).
463 Fixed bug in decoder for Explain (Category TargetInfo).
465 Added support for GNU readline in client. Thanks to Jacob Poulsen
466 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
468 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
469 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
470 IMPLEMENTATION! This change was made to the development version before
471 the ZIG decided to retract the amendment. If any users MUST be
472 compatible with the original Update definition, PLEASE CONTACT US, and
473 we will include a separate definition corresponding to the old Update
474 ES. Note that because of the change to the ASN.1 of the
475 TaskPackageRecordStructure we cannot define a single structure that
476 will support both versions.
478 * Added const modifier to buffer parameter for some ODR/BER encoding
479 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
480 completeWAIS, odr_dumpBER.
482 Fixed bug in client.c which caused a crash when a scanResponse didn't
483 contain positionOfTerm.
485 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
486 * will cause an error in a client if a non-YAZ target sends both a
487 * list of Scan entries and non-surrogate diagnostics.
489 Retrieval module enhancements. Tag sets may be typed in the reference
490 to it. From the .abs-file the "tagset" directive takes a third optional
491 integer type for the tag set referenced. From a .tag-file the "include"
492 directive takes a third optional type as well. The old "type" directive
493 in the tag set itself is still recognized but acts as the default type
496 Backend interface change. Individual Scan terms returned from bend_scan
497 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
498 in include/backend.h.
500 Retrieval module enhancements. Multiple tag sets and attribute sets may
501 be specified in abstract syntax specs. Revised the error/warning for
502 logging messages reported by the retrieval module when reading the
505 Object Identifier system (oid_..) changed. The API is backwards
506 compatible but the oid-routines now allocates new OID's when needed.
507 Raw OID's may be specified in oid_getvalbyname.
509 YAZ now uses GNU configure to generate Makefile(s).
511 * Minor changes in some of the member names of DeleteResultSetRequest and
512 DeleteResultSetResponse. See include/proto.h.
514 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
515 and added member 'languages' in TargetInfo (which was missing).
517 Changed the way attribute sets are handled in the retrieval
518 module. These are now cached, just like the abstract syntaxes
521 Changed YAZ so that it links with compiled ASN.1.
523 Added Explain-schema definitions and mapping routines. The following
524 Explain categories have been implemented: AttributeDetails,
525 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
527 Fixed minor bug in Windows version of Server Library.
529 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
531 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
533 Added EXTERNAL: UNIverse Resource Report (non-standard).
535 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
536 ENUMERATED and SET OF.
538 * Added 'const' to some of the char pointer arguments for the
539 functions, data1_read_node, data1_getelementbytagname,
540 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
543 Fixed bug in data1_insert_taggeddata - the last_child member of
544 parent wasn't initialised.
546 * Changed data1_read_record and data1_read_node so that the supplied
547 "SGML"-buffer is read-only. In particular the resulting data1 - tree
548 doesn't refer to any parts of the "SGML"-buffer.
550 Fixed bug in server library (Windows version of statserv_remove).
552 * Changed code so that it compiles as C++. The type definition
553 of Odr_fun which is a member of Odr_arm was changed. The result is,
554 that an explicit typecast is needed for the fun pointer when
555 using Odr_arm - as in:
556 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
558 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
560 Implemented the new structured date and time definition as approved
561 by the ZIG. Added schemaId element to the specificTag in Espec-1
562 (also approved at the last ZIG). Thanks to RVDM.
564 Added some Object identifiers (RVDM).
566 Changed the Update Extended Service (RVDM).
568 Added command "refid" to client which specifies referenceId for
569 the following requests.
571 Implemented extended service handling for server. See ztest.c
572 for an example as well as backend.h. New handlers are registerd
575 * Changed interface for sort in server.
577 Added new members to statserv_options_block. It allows a server
578 to read options from another source than just the command line. Thanks
579 to Charles Woodfield.
581 * Changed definition of Z_Triple in file prt-grs.h - member boolean
582 renamed to zboolean. Some C++ compilers complained about the name.
584 Minor changes to gils.abs. Added index 's' (sort) on title
585 and date/time-last-modified.
589 Fixed bug in server library regarding inetd mode (-i). This bug
590 was introduced by release 1.4.
594 Added sort facility in client and backend server interface.
596 Fixed problem with dependencies in Makefile(s).
598 Fixed bugs for encoders/decoders of extended services and
601 Implemented sub-tree feature for schemas. Sub-trees are
602 referenced in *.abs-files. See explain.abs for an example
603 of the use of this feature.
605 Modified bib1.att; local attributes for ANY didn't include
606 ANY itself (only affects use of the retrieval module).
608 Fixed bug in plain SGML reader in function data1_read_node:
609 tags with prefix "var" was incorrectly interpreted as variants.
611 Added feature "sub-schemas" to enable references to - and definitions
612 of - group of elements.
614 * Removed member parent from type data1_element (in data1.h).
616 Implemented function odr_nullval() that returns the value of
619 * Removed member num_children from data1_node (in data1.h).
621 Made NT service interface part of the server library. The
622 function statserv_main uses the NT service when required and
623 calls the statserv_start / statserv_close routines.
625 Routine zget_SearchRequest and zget_PresentRequest fills
626 resultSetName/Id member with "default" instead of "Default".
628 Fixed memory leak in server. Request queue member wasn't freed.
630 Fixed nmem_exit so that memory is freed.
634 Revised the CCL parser utility to be thread safe.
636 Added function, oid_ent_to_oid, to replace the function
637 oid_getoidbyent, which is not thread safe.
639 * Added nmem_init and nmem_exit to initialize and release
640 NMEM resources. Function nmem_init should be called once in the
641 initial thread before NMEM/ODR is used. statserv.c and client.c
642 have been changed accordingly. The change was necessary to make
643 NMEM thread safe. The NMEM memory pool is shared amongst threads
644 in a process. Unix-based applications will still work fine without
647 Added NT Services interface for the the Z39.50 (statserv) Server.
648 Refer to the ztest.c source on the usage.
650 Windows 95/NT port using MSVC5.0. Project files are included in the
653 * Defined new 'global' handle for the retrieval (data1) system. The
654 new handled, data1_handle, describes the state of the data1 system.
655 This handle is passed as first argument to virtually all
656 data1 related routines. The functions data1_create and data1_destroy
657 creates and destroys a data1 handle respectively.
659 Added ODR encode stream member to all backend request structures
660 init, search, scan etc. This stream should be used to allocate all
661 memory used for the response when thread safe operation is needed.
663 Changed the comstack utility, cs_addstr, to be thread safe. The
664 returned hostname string returned by the function is now part the
667 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
668 function. The cs_straddr takes a COMSTACK handle as argument, so this
669 function must be used after cs_create and before bind/connect.
670 This function is thread safe.
672 Moved test server to 'ztest' directory - generic server code still
673 in 'server' directory.
675 Made prefix query (pquery.c) utility thread safe.
677 Added new function modifier YAZ_EXPORT to 'export' public DLL
678 functions when using windows (see include/yconfig.h).
680 Added definitions to the OID database (util/oid.c) (RVDM).
682 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
684 Added call to ccl_rpn_delete in client program.
686 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
687 release of RPN structure.
689 Added support for C++, headers uses extern "C" for public definitions.
690 With input from RVDM.
692 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
693 Thanks to Ronald van der Meer (RVDM).
695 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
697 Added support for private extensions to the OID database
698 (oid_setprivateoids()). Thanks to RVDM.
700 Added optional, physical ANY (key replication)
702 Fixed null-reference problem in GRS-1 output filter.
704 Proximity operator added to Prefix Query Format (PQF).
706 In test client command "base" accepts multiple databases.
708 Fixed bug in cs_close stack that caused trouble with WINSOCK.
712 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
714 Smallish bug-fixes in the new encoders/decoders (explain).

724 Added Update extended service.
726 Added SearchResult-1 additional info structure.
728 Added optional CCL (ISO8777) interpreter as separate module. Available
731 --- 1.2 1996/6/10 (1st anniversary release)
733 Added Summary record syntax. Lightly tested.
735 Added OPAC record syntax. Untested.
737 Added ResourceReport service encoders/decoders. Untested.
739 Fixed bug in z_Unit - wrong tagging on unitSystem.
741 Fixed bug in the DiagRecs decoder.
743 Added options for max PDU size and session timeout to frontend-server.
745 Added documentation of query-language parsers and other supporting utilities.
747 [frontend-server] Added Attribute set to the bend_scanrequest API.
749 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
750 surrogate diagnostics were generated.
752 [retrieval] Allow multiple local values for attribute.
754 [retrieval] Allow multiple attributes per element in .abs files. index type.
756 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
760 Minor changes, mostly specific to Zebra's requirements (retrieval)
764 Repaired bug in frontend server when running multiple listening
765 endpoints in dynamic mode.
767 z_External() now won't break if a known, ASN.1 value comes encapsulated
768 in an octet-string. The value will pass through unmodified in an Odr_oct.
770 Added a bit of code to the demo client to decode & display
771 ASN.1-structured records represented in the octet-aligned branch of
772 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
774 Added z_ext_getentbyref() to the ASN module. Doc updated.
776 * Completed the SCAN definition in the ASN module. This may break SCAN
777 code based on older YAZ-versions at compile-time. The fix is easy -
780 * Added 'displayTerm' and OtherInformation to the TermInfo structure
781 under the SCAN definition. Remember to initialize this, server-people.
783 Comstack should now support the WAIS protocol in TCP/IP mode. Note
784 that this does not extend to ODR and ASN.
786 Comstack allows insertion of established socket (primarily for
787 inetd-operation of servers). Doc updated.
789 Front-end server can now start from the inetd in TCP mode. Doc
796 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
797 the rank and record number.
799 Adjustments to the frontend server.
801 Fixed diagnostic BER dumper. It ignored the file argument.
805 Various changes to retrieval module.
807 Changed the union discriminators of the protocol files from enums to
808 ints paired with #defines.
810 *Changed oident.class to oident.oclass to avoid a reserved word in C++
813 *Changed operator in the RPN structure to 'roperator', again to avoid a
816 Fixed problems in Explain decoders/encoders.
820 Memory bug in log module fixed.
824 Occasional malloc() of 0 bytes fixed in d1_espec.c.
826 Bug in Explain DatabaseInfo module fixed.
828 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
832 The shift to v1.0 signals that we now consider the *core* functionality
833 of YAZ reasonably stable (the core being more or less equivalent to
834 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
835 tested (Explain not at all - though that will happen soonish).
837 Minor changes to code to support Windows port.
839 Various minor changes after we're getting to use GRS-1 & co. more.
841 Added Espec-1 format.
843 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
844 of the protocol and it cannot be selected when encoding (maps into 'string'
845 when decoding). Needed to talk to some servers.
847 Demo client can request simple element set names.
849 Added Diagnostic Format encoders/decoders.
851 Added simple Close handling to frontend server (no hooks for resource
852 reporting yet), and demonstration client.
854 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
858 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
859 handled incorrectly when records were requested in the searchResponse. This
860 will only affect you if you use the frontend-server.
862 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
863 Test-client will ask for and print GRS1. Ztest will return dummy records
866 Added Explain encoders/decoders to the service-level API. Untested.
868 Added Extended Services: Item Order encoders and decoders to the Service-
869 level API. Untested. We could use a recent copy of the pertinent bits
870 of the ILL protocol to add those bits.
872 Added diagnostic format 1 encoders/decoders to the service-level API.
875 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
876 odr_cons.c, which causes a more correct output.
878 Fixed handling of searchRequest in frontend server. NextResultSetPosition
879 was always set to 0 when no records were requested in the searchRequest.
881 * Added better external-handling. This shouldn't harm old code that
882 *encodes* externals. It can break code that looks for a
883 'single-ASN1-type' representation, since those types that are known
884 are now decoded immediately. Look at the SUTRS sample code in
885 seshigh.c and client.c. Documentation updated.
887 Handling of structured records in bend_fetchresponse. Length -1 marks
888 structured record, type is deduced from format field.
891 Fairly quick maintenance release to add SUTRS support.
893 Fixed handling of SUTRS records in the demonstration client.
895 * Added format field to the bend_fetchrequest and bend_fetchresponce
896 structures of the backend API (frontend server). When the record is
897 returned, the value of the format field is mapped to an OID. The
898 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
899 of the record. The special value VAL_NONE in the bend_request means
900 that no specific format was requested by the client. Documentation
901 updated accordingly. Test server (ztest) will return a fixed dummy
902 SUTRS record if your client requests SUTRS.
904 Documentation updated accordingly.
906 You can now set external libraries and RANLIB support in the top-level
910 First public release.
