1 Possible compatibility problems with earlier versions marked with '*'.
11 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
14 Smallish bug-fixes in the new encoders/decoders (explain).

20 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
22 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
28 Added SOIF syntax (using private OID for now) to retrieval module and client.
31 --- 1.2 1996/6/10 (1st anniversary release)
33 Added Summary record syntax. Lightly tested.
35 Added OPAC record syntax. Untested.
37 Added ResourceReport service encoders/decoders. Untested.

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