---- XXXXX
+--- 1.4pl2 1998/1/30
-Added NT Services interface for Z39.50 Server.
+Fixed bug in server library regarding inetd mode (-i). This bug
+was introduced by release 1.4.
-Windows 95/NT port using MSV5.0. Project files are included in
-the distribution.
+--- 1.4pl1 1998/1/29
+
+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.
Moved test server to 'ztest' directory - generic server code still
in 'server' directory.
-Made prefix query handling thread safe.
+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).
