1 Possible compatibility problems with earlier versions marked with '*'.
5 Prefix query parser reports "fail" when bad attribute set is given.
7 Fix in MARC decoder. Proximity logging. Fix for attribute set
8 in scan handler for server. Patches by Shigeru Ishida.
10 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
13 Configure option --with-openssl=<dir> now works when a directory is
14 specified. Patch provided by Morten Bøgeskov.
16 New option for YAZ client, -u <auth>, that sets authentication.
18 ZOOM fix: error information only cleared for Bib-diagnostics (not
19 fatal errors, like connection failed, etc).
21 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
25 Scan for ZOOM API. New object ZOOM_scanset. New functions
26 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
29 New ZOOM function, ZOOM_connection_last_event, that returns type
30 of last event (such as "receive data", "send data", "apdu received",
33 New ZOOM option, schema, that specifies shema OID for retrieval.
35 New CCL feature. Qualifiers can be aliases for one or more
36 other qualifiers (if more than one is given, OR is used).
38 ZOOM uses named result sets if target supports it.
40 Two new YAZ client commands: . (dot, which sources a script of YAZ
41 client commands), and ! (to execute shell command.). Implemented
44 Working on Debian packages.
48 YAZ client enables named result sets only if target supports it.
50 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
52 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
53 with key="host" to get same result.
55 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
56 Function Z3950_resultset_record(s) returns references to records
57 "owned" by resultset. To become owner use Z3950_record_clone.
59 Function z_ext_record handles Extended Services. Thanks to
64 CCL Parser fix: ignore token comma when dealing with and-lists.
66 Documentation updates for COMSTACK.
68 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
69 Changed prototype Z3950_records. For some functions, int parameters
70 were changed to size_t.
72 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
75 New MARC decode/display function, marc_display_exl, which properly rejects
76 non-ISO2709 records. YAZ client uses it.
80 Fix bug: local attribute set wasn't set correctly in PQF strings.
84 * Old Z39.50 codecs no longer supported.
86 Added ZOOM C binding. See http://zoom.z3950.org/
88 Renamed states for COMSTACKs to avoid confusion with events.
90 Implemented cs_look and proper cs_rcvconnect.
92 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
94 Configure detects POSIX threads on OpenBSD.
96 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
97 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
99 When error is returned from present handler, non-surrogate diagnostic
100 is returned in present response (and fetch handler is no longer called).
102 * Minor adjustments to pquery parser (PQF). Token characters may be
103 escaped by using backslash (C-style).
105 PQF parser allows string attribute values to be specified. For @attr,
106 non-numeric characters after the equal-sign are treated as strings
107 (e.g. @attr 9=title).
109 CCL trunction character may be defined (@truncation in file)
111 * function zget_ExtendedServicesRequest sets waitAction to
112 waitIfPossible (was wait).
114 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
117 CCL operator names may be set in field definition files (CCL_bibset).
118 See ccl/bib1 for an example.
120 Fixes in ASN.1 compiler for C++ compatibility.
122 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
123 and "op_or" to avoid conflict with C++.
125 Fixed problem with GNU readline detection on Redhat 7.0.
127 Added step-size for Scan backend handler.
129 Fixed bug that made the frontend server crash when no attribute
130 set was specified for scan.
132 Front-end server automatically switches to original working directory
133 when installed as an NT service. Previously -w had to be specified to
136 Added extended attributes for retrieval module (data1), so that data1
137 records carry d1_readXML/SGML attributes. d1_read also supports
138 null-data rules ( <tag/>)
140 On UNIX when POSIX threads are available, a separate library libyazthread
141 is created. Programmers should link with that library and the yaz library
142 when using threads. The reason for the split was that some applications
143 on Linux, such as Apache, doesn't work well when using shared objects that
146 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
147 (or any frontend server) in SSL mode by specifying ssl: followed by
148 address. Only tested on UNIX.
150 Added feature for CCL module. Virtual structure s=al or s=ol generates
151 and-list and or-list respectively instead of phrase search.
155 * Added prefix "yaz_" for the functions log_init.., log_file.. and
156 log_mask_str. This was done to avoid name conflicts with other libraries
157 (such as other PHP extensions).
159 Added raw OID member for preferred record syntax (request_format_raw)
160 and returned record syntax (output_format_raw) for backend fetch method.
162 Config file yaz-config now accepts options so that it returns specific
163 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
165 Shared library support for UNIX using GNU libtool.
167 * Modified backend interface. Request/Response struct's replaced by
168 one read/write C struct. For example bend_fetchrequest and
169 bend_fetchresult have been replaced by single bend_fetch_rr struct.
170 Every handler - even search has to be registered in bend_init
171 handler. This means that the YAZ library no longer refers to
172 external functions and it makes it possible to make the whole
173 thing a single DLL/SO.
175 Added Segment handler for backend server.
177 Added Zmbol/Zebra administrative functions to YAZ client.
179 Threaded frontend server on UNIX (when POSIX Threads are available).
180 Starting the server with option -T enables multi-threading.
184 Added configure option --enable-comp/disable-comp to control use
185 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
186 located in sub directory asn.
188 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
189 in ${exec_prefix}/bin along with the other programs yaz-client and
192 GNU automake used to maintain makefiles.
196 Changed retrieval module so that we can load records with no abstract
197 syntax defined. Tagpaths in these records are fully composed of string
200 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
204 On UNIX, the generated makefile now supports a proper 'make install'.
205 The prefix can be set via GNU configure to set the install location
206 (default is /usr/local).
208 * YAZ programs client and ztest were renamed to yaz-client and
209 yaz-ztest to avoid conflicts when users install YAZ in "standard"
210 locations, such as /usr/bin,/usr/local/bin,etc.
212 * YAZ Header files were moved from include to include/yaz. YAZ Header
213 files are referred to as include <yaz/log.h> rather than <log.h>.
214 The YAZ include path (-I ..) is therefore the same as before. Programmers
215 should update their #include statements or use -Ipath/include/yaz
216 instead. The main motivation for doing this change is that YAZ header files
217 can be installed in "standard" locations /usr/include,/usr/local/include
218 without introducing conflicts, since ALL YAZ header files are stored
219 in subdirectory yaz (under /usr/include for example).
221 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
222 rather than project/workspace files. We switched because project files
223 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
226 Changed name of logging function, logf, to yaz_log, to prevent name
227 clash with some math-log functions. The YAZ header log.h defines logf
228 to yaz_log (#define) so there should be no incompatibilities by this
231 Added bend_start/bend_stop handlers for server. These handler are
232 called on start/stop of server. For windows they are called whenever
233 a service is started/stopped.
235 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
236 a fairly small ASN.1 compiler written in Tcl. The compiler is located
237 in util/yc.tcl. The auto-generated C code structures are, in a few
238 cases, incompatible with the old decoders. There are differences in the
239 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
240 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
241 The preprocessor variable ASN_COMPILED is defined when the compiled
242 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
243 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
244 wish to use the old encoders/decoders you can specify --disable-yc
247 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
248 version so that it supports both new - and old version of DB Update
250 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
251 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
252 change. The name parameter can be set to 0 in which no name is specified
253 for the construction. The macros odr_implicit and odr_explicit sets name
254 parameter to zero for the construction involved. New macros
255 odr_implicit_tag and odr_explicit_tag are similar to the others,
256 except that a name parameter is added. For programmers' that don't use
257 ODR they probably only need to change the call to z_APDU and z_External.
259 Added access control facility by interfacing the TCP wrapper library.
260 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
261 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
262 name of the daemon and enables the access control as specified in
263 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
265 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
266 den Dool <H.M.vdnDool@kub.nl>.
268 Added reference ID parameter to most functions in server API - refer
269 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
271 Changed name of ccl library to libccl.a (was ccl.a).
273 Fixed bug in decoder for Explain (Category TargetInfo).
275 Added support for GNU readline in client. Thanks to Jacob Poulsen
276 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
278 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
279 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
280 IMPLEMENTATION! This change was made to the development version before
281 the ZIG decided to retract the amendment. If any users MUST be
282 compatible with the original Update definition, PLEASE CONTACT US, and
283 we will include a separate definition corresponding to the old Update
284 ES. Note that because of the change to the ASN.1 of the
285 TaskPackageRecordStructure we cannot define a single structure that
286 will support both versions.
288 * Added const modifier to buffer parameter for some ODR/BER encoding
289 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
290 completeWAIS, odr_dumpBER.
292 Fixed bug in client.c which caused a crash when a scanResponse didn't
293 contain positionOfTerm.
295 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
296 * will cause an error in a client if a non-YAZ target sends both a
297 * list of Scan entries and non-surrogate diagnostics.
299 Retrieval module enhancements. Tag sets may be typed in the reference
300 to it. From the .abs-file the "tagset" directive takes a third optional
301 integer type for the tag set referenced. From a .tag-file the "include"
302 directive takes a third optional type as well. The old "type" directive
303 in the tag set itself is still recognized but acts as the default type
306 Backend interface change. Individual Scan terms returned from bend_scan
307 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
308 in include/backend.h.
310 Retrieval module enhancements. Multiple tag sets and attribute sets may
311 be specified in abstract syntax specs. Revised the error/warning for
312 logging messages reported by the retrieval module when reading the
315 Object Identifier system (oid_..) changed. The API is backwards
316 compatible but the oid-routines now allocates new OID's when needed.
317 Raw OID's may be specified in oid_getvalbyname.
319 YAZ now uses GNU configure to generate Makefile(s).
321 * Minor changes in some of the member names of DeleteResultSetRequest and
322 DeleteResultSetResponse. See include/proto.h.
324 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
325 and added member 'languages' in TargetInfo (which was missing).
327 Changed the way attribute sets are handled in the retrieval
328 module. These are now cached, just like the abstract syntaxes
331 Changed YAZ so that it links with compiled ASN.1.
333 Added Explain-schema definitions and mapping routines. The following
334 Explain categories have been implemented: AttributeDetails,
335 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
337 Fixed minor bug in Windows version of Server Library.
339 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
341 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
343 Added EXTERNAL: UNIverse Resource Report (non-standard).
345 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
346 ENUMERATED and SET OF.
348 * Added 'const' to some of the char pointer arguments for the
349 functions, data1_read_node, data1_getelementbytagname,
350 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
353 Fixed bug in data1_insert_taggeddata - the last_child member of
354 parent wasn't initialised.
356 * Changed data1_read_record and data1_read_node so that the supplied
357 "SGML"-buffer is read-only. In particular the resulting data1 - tree
358 doesn't refer to any parts of the "SGML"-buffer.
360 Fixed bug in server library (Windows version of statserv_remove).
362 * Changed code so that it compiles as C++. The type definition
363 of Odr_fun which is a member of Odr_arm was changed. The result is,
364 that an explicit typecast is needed for the fun pointer when
365 using Odr_arm - as in:
366 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
368 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
370 Implemented the new structured date and time definition as approved
371 by the ZIG. Added schemaId element to the specificTag in Espec-1
372 (also approved at the last ZIG). Thanks to RVDM.
374 Added some Object identifiers (RVDM).
376 Changed the Update Extended Service (RVDM).
378 Added command "refid" to client which specifies referenceId for
379 the following requests.
381 Implemented extended service handling for server. See ztest.c
382 for an example as well as backend.h. New handlers are registerd
385 * Changed interface for sort in server.
387 Added new members to statserv_options_block. It allows a server
388 to read options from another source than just the command line. Thanks
389 to Charles Woodfield.
391 * Changed definition of Z_Triple in file prt-grs.h - member boolean
392 renamed to zboolean. Some C++ compilers complained about the name.
394 Minor changes to gils.abs. Added index 's' (sort) on title
395 and date/time-last-modified.
399 Fixed bug in server library regarding inetd mode (-i). This bug
400 was introduced by release 1.4.
404 Added sort facility in client and backend server interface.
406 Fixed problem with dependencies in Makefile(s).
408 Fixed bugs for encoders/decoders of extended services and
411 Implemented sub-tree feature for schemas. Sub-trees are
412 referenced in *.abs-files. See explain.abs for an example
413 of the use of this feature.
415 Modified bib1.att; local attributes for ANY didn't include
416 ANY itself (only affects use of the retrieval module).
418 Fixed bug in plain SGML reader in function data1_read_node:
419 tags with prefix "var" was incorrectly interpreted as variants.
421 Added feature "sub-schemas" to enable references to - and definitions
422 of - group of elements.
424 * Removed member parent from type data1_element (in data1.h).
426 Implemented function odr_nullval() that returns the value of
429 * Removed member num_children from data1_node (in data1.h).
431 Made NT service interface part of the server library. The
432 function statserv_main uses the NT service when required and
433 calls the statserv_start / statserv_close routines.
435 Routine zget_SearchRequest and zget_PresentRequest fills
436 resultSetName/Id member with "default" instead of "Default".
438 Fixed memory leak in server. Request queue member wasn't freed.
440 Fixed nmem_exit so that memory is freed.
444 Revised the CCL parser utility to be thread safe.
446 Added function, oid_ent_to_oid, to replace the function
447 oid_getoidbyent, which is not thread safe.
449 * Added nmem_init and nmem_exit to initialize and release
450 NMEM resources. Function nmem_init should be called once in the
451 initial thread before NMEM/ODR is used. statserv.c and client.c
452 have been changed accordingly. The change was necessary to make
453 NMEM thread safe. The NMEM memory pool is shared amongst threads
454 in a process. Unix-based applications will still work fine without
457 Added NT Services interface for the the Z39.50 (statserv) Server.
458 Refer to the ztest.c source on the usage.
460 Windows 95/NT port using MSVC5.0. Project files are included in the
463 * Defined new 'global' handle for the retrieval (data1) system. The
464 new handled, data1_handle, describes the state of the data1 system.
465 This handle is passed as first argument to virtually all
466 data1 related routines. The functions data1_create and data1_destroy
467 creates and destroys a data1 handle respectively.
469 Added ODR encode stream member to all backend request structures
470 init, search, scan etc. This stream should be used to allocate all
471 memory used for the response when thread safe operation is needed.
473 Changed the comstack utility, cs_addstr, to be thread safe. The
474 returned hostname string returned by the function is now part the
477 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
478 function. The cs_straddr takes a COMSTACK handle as argument, so this
479 function must be used after cs_create and before bind/connect.
480 This function is thread safe.
482 Moved test server to 'ztest' directory - generic server code still
483 in 'server' directory.
485 Made prefix query (pquery.c) utility thread safe.
487 Added new function modifier YAZ_EXPORT to 'export' public DLL
488 functions when using windows (see include/yconfig.h).
490 Added definitions to the OID database (util/oid.c) (RVDM).
492 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
494 Added call to ccl_rpn_delete in client program.
496 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
497 release of RPN structure.
499 Added support for C++, headers uses extern "C" for public definitions.
500 With input from RVDM.
502 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
503 Thanks to Ronald van der Meer (RVDM).
505 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
507 Added support for private extensions to the OID database
508 (oid_setprivateoids()). Thanks to RVDM.
510 Added optional, physical ANY (key replication)
512 Fixed null-reference problem in GRS-1 output filter.
514 Proximity operator added to Prefix Query Format (PQF).
516 In test client command "base" accepts multiple databases.
518 Fixed bug in cs_close stack that caused trouble with WINSOCK.
522 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
524 Smallish bug-fixes in the new encoders/decoders (explain).
526 Bug fixed in DeleteRequest.
528 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
530 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
532 Added SOIF syntax (using private OID for now) to retrieval module and client.
534 Added Update extended service.
536 Added SearchResult-1 additional info structure.
538 Added optional CCL (ISO8777) interpreter as separate module. Available
541 --- 1.2 1996/6/10 (1st anniversary release)
543 Added Summary record syntax. Lightly tested.
545 Added OPAC record syntax. Untested.
547 Added ResourceReport service encoders/decoders. Untested.
549 Fixed bug in z_Unit - wrong tagging on unitSystem.
551 Fixed bug in the DiagRecs decoder.
553 Added options for max PDU size and session timeout to frontend-server.
555 Added documentation of query-language parsers and other supporting utilities.
557 [frontend-server] Added Attribute set to the bend_scanrequest API.
559 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
560 surrogate diagnostics were generated.
562 [retrieval] Allow multiple local values for attribute.
564 [retrieval] Allow multiple attributes per element in .abs files. index type.
566 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
570 Minor changes, mostly specific to Zebra's requirements (retrieval)
574 Repaired bug in frontend server when running multiple listening
575 endpoints in dynamic mode.
577 z_External() now won't break if a known, ASN.1 value comes encapsulated
578 in an octet-string. The value will pass through unmodified in an Odr_oct.
580 Added a bit of code to the demo client to decode & display
581 ASN.1-structured records represented in the octet-aligned branch of
582 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
584 Added z_ext_getentbyref() to the ASN module. Doc updated.
586 * Completed the SCAN definition in the ASN module. This may break SCAN
587 code based on older YAZ-versions at compile-time. The fix is easy -
590 * Added 'displayTerm' and OtherInformation to the TermInfo structure
591 under the SCAN definition. Remember to initialize this, server-people.
593 Comstack should now support the WAIS protocol in TCP/IP mode. Note
594 that this does not extend to ODR and ASN.
596 Comstack allows insertion of established socket (primarily for
597 inetd-operation of servers). Doc updated.
599 Front-end server can now start from the inetd in TCP mode. Doc
606 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
607 the rank and record number.
609 Adjustments to the frontend server.
611 Fixed diagnostic BER dumper. It ignored the file argument.
615 Various changes to retrieval module.
617 Changed the union discriminators of the protocol files from enums to
618 ints paired with #defines.
620 *Changed oident.class to oident.oclass to avoid a reserved word in C++
623 *Changed operator in the RPN structure to 'roperator', again to avoid a
626 Fixed problems in Explain decoders/encoders.
630 Memory bug in log module fixed.
634 Occasional malloc() of 0 bytes fixed in d1_espec.c.
636 Bug in Explain DatabaseInfo module fixed.
638 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
642 The shift to v1.0 signals that we now consider the *core* functionality
643 of YAZ reasonably stable (the core being more or less equivalent to
644 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
645 tested (Explain not at all - though that will happen soonish).
647 Minor changes to code to support Windows port.
649 Various minor changes after we're getting to use GRS-1 & co. more.
651 Added Espec-1 format.
653 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
654 of the protocol and it cannot be selected when encoding (maps into 'string'
655 when decoding). Needed to talk to some servers.
657 Demo client can request simple element set names.
659 Added Diagnostic Format encoders/decoders.
661 Added simple Close handling to frontend server (no hooks for resource
662 reporting yet), and demonstration client.
664 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
668 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
669 handled incorrectly when records were requested in the searchResponse. This
670 will only affect you if you use the frontend-server.
672 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
673 Test-client will ask for and print GRS1. Ztest will return dummy records
676 Added Explain encoders/decoders to the service-level API. Untested.
678 Added Extended Services: Item Order encoders and decoders to the Service-
679 level API. Untested. We could use a recent copy of the pertinent bits
680 of the ILL protocol to add those bits.
682 Added diagnostic format 1 encoders/decoders to the service-level API.
685 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
686 odr_cons.c, which causes a more correct output.
688 Fixed handling of searchRequest in frontend server. NextResultSetPosition
689 was always set to 0 when no records were requested in the searchRequest.
691 * Added better external-handling. This shouldn't harm old code that
692 *encodes* externals. It can break code that looks for a
693 'single-ASN1-type' representation, since those types that are known
694 are now decoded immediately. Look at the SUTRS sample code in
695 seshigh.c and client.c. Documentation updated.
697 Handling of structured records in bend_fetchresponse. Length -1 marks
698 structured record, type is deduced from format field.
701 Fairly quick maintenance release to add SUTRS support.
703 Fixed handling of SUTRS records in the demonstration client.
705 * Added format field to the bend_fetchrequest and bend_fetchresponce
706 structures of the backend API (frontend server). When the record is
707 returned, the value of the format field is mapped to an OID. The
708 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
709 of the record. The special value VAL_NONE in the bend_request means
710 that no specific format was requested by the client. Documentation
711 updated accordingly. Test server (ztest) will return a fixed dummy
712 SUTRS record if your client requests SUTRS.
714 Documentation updated accordingly.
716 You can now set external libraries and RANLIB support in the top-level
720 First public release.
