1 Possible compatibility problems with earlier versions marked with '*'.
5 Added support for C++, headers uses extern "C" for public definitions.
8 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
9 Thanks to Ronald van der Meer (RVDM).
11 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.

47 --- 1.2 1996/6/10 (1st anniversary release)
49 Added Summary record syntax. Lightly tested.
51 Added OPAC record syntax. Untested.
53 Added ResourceReport service encoders/decoders. Untested.
55 Fixed bug in z_Unit - wrong tagging on unitSystem.
57 Fixed bug in the DiagRecs decoder.
59 Added options for max PDU size and session timeout to frontend-server.
61 Added documentation of query-language parsers and other supporting utilities.
63 [frontend-server] Added Attribute set to the bend_scanrequest API.
65 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
66 surrogate diagnostics were generated.
68 [retrieval] Allow multiple local values for attribute.
70 [retrieval] Allow multiple attributes per element in .abs files. index type.
72 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
76 Minor changes, mostly specific to Zebra's requirements (retrieval)
80 Repaired bug in frontend server when running multiple listening
81 endpoints in dynamic mode.
83 z_External() now won't break if a known, ASN.1 value comes encapsulated
84 in an octet-string. The value will pass through unmodified in an Odr_oct.
86 Added a bit of code to the demo client to decode & display
87 ASN.1-structured records represented in the octet-aligned branch of
88 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
90 Added z_ext_getentbyref() to the ASN module. Doc updated.
92 * Completed the SCAN definition in the ASN module. This may break SCAN
93 code based on older YAZ-versions at compile-time. The fix is easy -
96 * Added 'displayTerm' and OtherInformation to the TermInfo structure
97 under the SCAN definition. Remember to initialize this, server-people.
99 Comstack should now support the WAIS protocol in TCP/IP mode. Note
100 that this does not extend to ODR and ASN.
102 Comstack allows insertion of established socket (primarily for
103 inetd-operation of servers). Doc updated.
105 Front-end server can now start from the inetd in TCP mode. Doc
112 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
113 the rank and record number.
115 Adjustments to the frontend server.
117 Fixed diagnostic BER dumper. It ignored the file argument.
121 Various changes to retrieval module.
123 Changed the union discriminators of the protocol files from enums to
124 ints paired with #defines.
126 *Changed oident.class to oident.oclass to avoid a reserved word in C++
129 *Changed operator in the RPN structure to 'roperator', again to avoid a
132 Fixed problems in Explain decoders/encoders.
136 Memory bug in log module fixed.
140 Occasional malloc() of 0 bytes fixed in d1_espec.c.
142 Bug in Explain DatabaseInfo module fixed.
144 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
148 The shift to v1.0 signals that we now consider the *core* functionality
149 of YAZ reasonably stable (the core being more or less equivalent to
150 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
151 tested (Explain not at all - though that will happen soonish).
153 Minor changes to code to support Windows port.
155 Various minor changes after we're getting to use GRS-1 & co. more.
157 Added Espec-1 format.
159 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
160 of the protocol and it cannot be selected when encoding (maps into 'string'
161 when decoding). Needed to talk to some servers.
163 Demo client can request simple element set names.
165 Added Diagnostic Format encoders/decoders.
167 Added simple Close handling to frontend server (no hooks for resource
168 reporting yet), and demonstration client.
170 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
174 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
175 handled incorrectly when records were requested in the searchResponse. This
176 will only affect you if you use the frontend-server.
178 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
179 Test-client will ask for and print GRS1. Ztest will return dummy records
182 Added Explain encoders/decoders to the service-level API. Untested.
184 Added Extended Services: Item Order encoders and decoders to the Service-
185 level API. Untested. We could use a recent copy of the pertinent bits
186 of the ILL protocol to add those bits.
188 Added diagnostic format 1 encoders/decoders to the service-level API.
191 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
192 odr_cons.c, which causes a more correct output.
194 Fixed handling of searchRequest in frontend server. NextResultSetPosition
195 was always set to 0 when no records were requested in the searchRequest.
197 * Added better external-handling. This shouldn't harm old code that
198 *encodes* externals. It can break code that looks for a
199 'single-ASN1-type' representation, since those types that are known
200 are now decoded immediately. Look at the SUTRS sample code in
201 seshigh.c and client.c. Documentation updated.
203 Handling of structured records in bend_fetchresponse. Length -1 marks
204 structured record, type is deduced from format field.
207 Fairly quick maintenance release to add SUTRS support.
209 Fixed handling of SUTRS records in the demonstration client.
211 * Added format field to the bend_fetchrequest and bend_fetchresponce
212 structures of the backend API (frontend server). When the record is
213 returned, the value of the format field is mapped to an OID. The
214 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
215 of the record. The special value VAL_NONE in the bend_request means
216 that no specific format was requested by the client. Documentation
217 updated accordingly. Test server (ztest) will return a fixed dummy
218 SUTRS record if your client requests SUTRS.
220 Documentation updated accordingly.
222 You can now set external libraries and RANLIB support in the top-level
226 First public release.
