+--- 1.4pl1 1998/1/29
+
Possible compatibility problems with earlier versions marked with '*'.
---- XXXXX XXXX/XX/XX
+Added sort facility in client and backend server interface.
+
+Fixed problem with dependencies in Makefile(s).
+
+Fixed bugs for encoders/decoders of extended services and
+SearchInfoReport.
+
+Implemented sub-tree feature for schemas. Sub-trees are
+referenced in *.abs-files. See explain.abs for an example
+of the use of this feature.
+
+Modified bib1.att; local attributes for ANY didn't include
+ANY itself (only affects use of the retrieval module).
+
+Fixed bug in plain SGML reader in function data1_read_node:
+tags with prefix "var" was incorrectly interpreted as variants.
+
+Added feature "sub-schemas" to enable references to - and definitions
+of - group of elements.
+
+* Removed member parent from type data1_element (in data1.h).
+
+Implemented function odr_nullval() that returns the value of
+ODR_NULLVAL.
+
+* Removed member num_children from data1_node (in data1.h).
+
+Made NT service interface part of the server library. The
+function statserv_main uses the NT service when required and
+calls the statserv_start / statserv_close routines.
+
+Routine zget_SearchRequest and zget_PresentRequest fills
+resultSetName/Id member with "default" instead of "Default".
+
+Fixed memory leak in server. Request queue member wasn't freed.
+
+Fixed nmem_exit so that memory is freed.
+
+--- 1.4 1997/10/2
+
+Revised the CCL parser utility to be thread safe.
+
+Added function, oid_ent_to_oid, to replace the function
+oid_getoidbyent, which is not thread safe.
+
+* Added nmem_init and nmem_exit to initialize and release
+NMEM resources. Function nmem_init should be called once in the
+initial thread before NMEM/ODR is used. statserv.c and client.c
+have been changed accordingly. The change was necessary to make
+NMEM thread safe. The NMEM memory pool is shared amongst threads
+in a process. Unix-based applications will still work fine without
+calling this.
+
+Added NT Services interface for the the Z39.50 (statserv) Server.
+Refer to the ztest.c source on the usage.
+
+Windows 95/NT port using MSVC5.0. Project files are included in the
+distribution.
+
+* Defined new 'global' handle for the retrieval (data1) system. The
+new handled, data1_handle, describes the state of the data1 system.
+This handle is passed as first argument to virtually all
+data1 related routines. The functions data1_create and data1_destroy
+creates and destroys a data1 handle respectively.
+
+Added ODR encode stream member to all backend request structures
+init, search, scan etc. This stream should be used to allocate all
+memory used for the response when thread safe operation is needed.
+
+Changed the comstack utility, cs_addstr, to be thread safe. The
+returned hostname string returned by the function is now part the
+COMSTACK instance.
+
+Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
+function. The cs_straddr takes a COMSTACK handle as argument, so this
+function must be used after cs_create and before bind/connect.
+This function is thread safe.
+
+Moved test server to 'ztest' directory - generic server code still
+in 'server' directory.
+
+Made prefix query (pquery.c) utility thread safe.
+
+Added new function modifier YAZ_EXPORT to 'export' public DLL
+functions when using windows (see include/yconfig.h).
+
+Added definitions to the OID database (util/oid.c) (RVDM).
+
+Added new BIB-1 diagnostic messages to the handler diagbib1_str.
+
+Added call to ccl_rpn_delete in client program.
+
+Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
+release of RPN structure.
+
+Added support for C++, headers uses extern "C" for public definitions.
+With input from RVDM.
+
+In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
+Thanks to Ronald van der Meer (RVDM).
+
+Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
+
+Added support for private extensions to the OID database
+(oid_setprivateoids()). Thanks to RVDM.
+
+Added optional, physical ANY (key replication)
+
+Fixed null-reference problem in GRS-1 output filter.
+
+Proximity operator added to Prefix Query Format (PQF).
+
+In test client command "base" accepts multiple databases.
+
+Fixed bug in cs_close stack that caused trouble with WINSOCK.
+
+--- 1.3 1996/10/11
+
+Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
+
+Smallish bug-fixes in the new encoders/decoders (explain).
+
+Bug fixed in DeleteRequest.
+
+Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
+
+Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
+
+Added SOIF syntax (using private OID for now) to retrieval module and client.
+
+Added Update extended service.
+
+Added SearchResult-1 additional info structure.
+
+Added optional CCL (ISO8777) interpreter as separate module. Available
+in linemode client.
+
+--- 1.2 1996/6/10 (1st anniversary release)
+
+Added Summary record syntax. Lightly tested.
+
+Added OPAC record syntax. Untested.
+
+Added ResourceReport service encoders/decoders. Untested.
+
+Fixed bug in z_Unit - wrong tagging on unitSystem.
+
+Fixed bug in the DiagRecs decoder.
+
+Added options for max PDU size and session timeout to frontend-server.
+
+Added documentation of query-language parsers and other supporting utilities.
+
+[frontend-server] Added Attribute set to the bend_scanrequest API.
+
+[frontend-server] NextResultSetPosition was sometimes set incorrectly when
+surrogate diagnostics were generated.
+
+[retrieval] Allow multiple local values for attribute.
+
+[retrieval] Allow multiple attributes per element in .abs files. index type.
+
+[retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
+
+--- 1.1pl2 1996/4/10
+
+Minor changes, mostly specific to Zebra's requirements (retrieval)
+
+--- 1.1 1996/2/20
+
+Repaired bug in frontend server when running multiple listening
+endpoints in dynamic mode.
+
+z_External() now won't break if a known, ASN.1 value comes encapsulated
+in an octet-string. The value will pass through unmodified in an Odr_oct.
+
+Added a bit of code to the demo client to decode & display
+ASN.1-structured records represented in the octet-aligned branch of
+the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
+
+Added z_ext_getentbyref() to the ASN module. Doc updated.
+
+* Completed the SCAN definition in the ASN module. This may break SCAN
+code based on older YAZ-versions at compile-time. The fix is easy -
+look in proto.h.
+
+* Added 'displayTerm' and OtherInformation to the TermInfo structure
+under the SCAN definition. Remember to initialize this, server-people.
+
+Comstack should now support the WAIS protocol in TCP/IP mode. Note
+that this does not extend to ODR and ASN.
+
+Comstack allows insertion of established socket (primarily for
+inetd-operation of servers). Doc updated.
-Front-end can now start from the inetd in TCP mode. Doc updated.
+Front-end server can now start from the inetd in TCP mode. Doc
+updated.
