1 Possible compatibility problems with earlier versions marked with '*'.
5 New windows 95/NT port using MSV5.0.
7 Moved test server to 'ztest' directory - generic server code still
10 Made prefix query handling thread safe.
12 Added new function modifier YAZ_EXPORT to 'export' public DLL
13 functions when using windows (see include/yconfig.h).
15 Added definitions to the OID database (util/oid.c) (RVDM).
17 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
19 Added call to ccl_rpn_delete in client program.
21 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
22 release of RPN structure.
24 Added support for C++, headers uses extern "C" for public definitions.
27 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
28 Thanks to Ronald van der Meer (RVDM).
30 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

66 --- 1.2 1996/6/10 (1st anniversary release)

70 Added OPAC record syntax. Untested.
72 Added ResourceReport service encoders/decoders. Untested.

76 Fixed bug in the DiagRecs decoder.
78 Added options for max PDU size and session timeout to frontend-server.
80 Added documentation of query-language parsers and other supporting utilities.
82 [frontend-server] Added Attribute set to the bend_scanrequest API.
84 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
85 surrogate diagnostics were generated.
87 [retrieval] Allow multiple local values for attribute.
89 [retrieval] Allow multiple attributes per element in .abs files. index type.
91 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
95 Minor changes, mostly specific to Zebra's requirements (retrieval)
99 Repaired bug in frontend server when running multiple listening
100 endpoints in dynamic mode.
102 z_External() now won't break if a known, ASN.1 value comes encapsulated
103 in an octet-string. The value will pass through unmodified in an Odr_oct.
105 Added a bit of code to the demo client to decode & display
106 ASN.1-structured records represented in the octet-aligned branch of
107 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
109 Added z_ext_getentbyref() to the ASN module. Doc updated.
111 * Completed the SCAN definition in the ASN module. This may break SCAN
112 code based on older YAZ-versions at compile-time. The fix is easy -
115 * Added 'displayTerm' and OtherInformation to the TermInfo structure
116 under the SCAN definition. Remember to initialize this, server-people.
118 Comstack should now support the WAIS protocol in TCP/IP mode. Note
119 that this does not extend to ODR and ASN.
121 Comstack allows insertion of established socket (primarily for
122 inetd-operation of servers). Doc updated.
124 Front-end server can now start from the inetd in TCP mode. Doc
131 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
132 the rank and record number.
134 Adjustments to the frontend server.
136 Fixed diagnostic BER dumper. It ignored the file argument.
140 Various changes to retrieval module.
142 Changed the union discriminators of the protocol files from enums to
143 ints paired with #defines.
145 *Changed oident.class to oident.oclass to avoid a reserved word in C++
148 *Changed operator in the RPN structure to 'roperator', again to avoid a
151 Fixed problems in Explain decoders/encoders.
155 Memory bug in log module fixed.
159 Occasional malloc() of 0 bytes fixed in d1_espec.c.
161 Bug in Explain DatabaseInfo module fixed.
163 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
167 The shift to v1.0 signals that we now consider the *core* functionality
168 of YAZ reasonably stable (the core being more or less equivalent to
169 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
170 tested (Explain not at all - though that will happen soonish).
172 Minor changes to code to support Windows port.
174 Various minor changes after we're getting to use GRS-1 & co. more.
176 Added Espec-1 format.
178 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
179 of the protocol and it cannot be selected when encoding (maps into 'string'
180 when decoding). Needed to talk to some servers.
182 Demo client can request simple element set names.
184 Added Diagnostic Format encoders/decoders.
186 Added simple Close handling to frontend server (no hooks for resource
187 reporting yet), and demonstration client.
189 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
193 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
194 handled incorrectly when records were requested in the searchResponse. This
195 will only affect you if you use the frontend-server.
197 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
198 Test-client will ask for and print GRS1. Ztest will return dummy records
201 Added Explain encoders/decoders to the service-level API. Untested.
203 Added Extended Services: Item Order encoders and decoders to the Service-
204 level API. Untested. We could use a recent copy of the pertinent bits
205 of the ILL protocol to add those bits.
207 Added diagnostic format 1 encoders/decoders to the service-level API.
210 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
211 odr_cons.c, which causes a more correct output.
213 Fixed handling of searchRequest in frontend server. NextResultSetPosition
214 was always set to 0 when no records were requested in the searchRequest.
216 * Added better external-handling. This shouldn't harm old code that
217 *encodes* externals. It can break code that looks for a
218 'single-ASN1-type' representation, since those types that are known
219 are now decoded immediately. Look at the SUTRS sample code in
220 seshigh.c and client.c. Documentation updated.
222 Handling of structured records in bend_fetchresponse. Length -1 marks
223 structured record, type is deduced from format field.
226 Fairly quick maintenance release to add SUTRS support.
228 Fixed handling of SUTRS records in the demonstration client.
230 * Added format field to the bend_fetchrequest and bend_fetchresponce
231 structures of the backend API (frontend server). When the record is
232 returned, the value of the format field is mapped to an OID. The
233 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
234 of the record. The special value VAL_NONE in the bend_request means
235 that no specific format was requested by the client. Documentation
236 updated accordingly. Test server (ztest) will return a fixed dummy
237 SUTRS record if your client requests SUTRS.
239 Documentation updated accordingly.
241 You can now set external libraries and RANLIB support in the top-level
245 First public release.
