+Remote record import using Z39.50 Extended Services and Segments.
+
+Fixed bug where updating a database with user-defined attributes
+could corrupt the register (bad storeKeys).
+
+Multi-threaded version.
+
+Fixed bug regarding proximity.
+
+Documentation updates.
+
+Fixed bug in record retrieval module that occured on 64-bit OSF 
+architectures.
+
+--- 1.0.1 2000/2/10
+
+Fixed bug in makefile for WIN32.
+
+Fixed bug in configure script - used bash-specific features.
+
+--- 1.0 1999/12/10
+
+The software was split in two products Zebra (for testing,
+non-profit use) and the commercial product Z'mbol. Zebra no
+longer supports INDEX UPDATES, i.e. zebraidx should be invoked only
+once for each register. Refer to LICENSE.zebra for more info.
+
+Added support for multiple records in one file for filter grs.sgml.
+
+Changed record index structure. New layout is incompatible with
+previous releases. Added setting "recordcompression" to control
+compression of records. Possible values are "none" (no
+compression) and bzip2 (compression using libbz2).
+
+Added XML transfer syntax support for retrieval of structured records.
+Schema in CompSpec is recognised in retrieval of structured records.
+
+Changed Tcl record filter so that it attemps to read  <filt>.tflt. If
+that fails, the filter reads the file <filt>.flt (regx style filter).
+
+Implemented new Tcl record filter -  use grs.tcl.<filter> to enable it.
+Zebra's configure script automatically attempts to locate Tcl. For
+manual Tcl configuration use option --with-tclconfig=<path> to specify
+where Tcl's library files are located.
+
+Implemented "compression" of Dictionary and ISAM system. Dictionary
+format HAS changed.
+
+Added "tagsysno" directive to zebra.cfg to control under which tag the
+system ID is placed. Use tagsysno: 0 to disable Zebra's system number
+entirely.
+
+Added "tagrank" as above.
+
+Changed file naming scheme for register files from <name>.mf.<no> to
+<name>-<no>.mf.
+
+Implemented "position"-flag for register type (as defined in
+default.idx). When set to zero no position (or seqence number) is
+saved in register for each word occurrence, thus saving some register
+space.
+
+Implemented database mapping. Using mapdb one can specify a database
+to be mapped to one or more physical databases. Usage:
+mapdb <fromdb> <todb> ..
+
+Added SOIF-filter. Thanks to Peter Valkenburg.
+
+For the regx-filter "end element -record" may trigger a mark-of-record
+if outer level is reached.
+
+Tag sets may be typed in the reference to it. From the .abs-file the
+"tagset" directive takes a third optional integer type for the tag set
+referenced. From a .tag-file the "include" directive takes a third
+optional type as well. The old "type" directive in the tag set itself
+is still recognized but acts as the default type for the tag set.
+ 
+Zebra supports the specification of arbitrary attributes sets, schemas
+and tag sets, because of the change in YAZ' OID management system.
+
+Fixed bug in Sort that caused it NOT to use character mapping as it
+should.
+
+Zebra now uses GNU configure to generate Makefile(s).
+
+Added un-optimised support for left and left/right truncation attributes.
+
+Added support for relational operators on text when using RPN queries.
+
+Added support for sort specifications in RPN queries. Type 7 specifies
+'sort' where value 1=ascending, value 2=descending. The use attribute
+specifies the field criteria as usual.  The term specifies priority
+where 0=first, 1=second, ...
+

 specification.

 Fixed register spec so that colon isn't treated as size separator
 unless followed by [0-9+-] in order to allow DOS drive specifications.
 
 Fixed two bugs in ISAMC system.

 inspect rank1.c and improve the algorithm.
