---- 2.0.0 2006/08/10
+For estimated hit counts, Zebra returns resultSetStatus=estimtate as
+part of SearchResponse. Requires YAZ 2.1.47 or later.
-New record filter (record type) alvis which uses XSLT to drive both
-indexing as well as retrieval.
+--- 2.0.8 2007/01/15
-isamb is now the default ISAM system. In Zebra 1.3, the default ISAM was
-isamc. The type used can still be configured with the 'isam' setting
-in zebra.cfg.
+For searches, do not truncate more than at most 'truncmax' terms in one
+single term with right-truncation/regular attribute. By default, 'truncmax',
+is 10000.
-Index structure is now 64-bit based. No more 2GB limits.
+Bug #781: Easier tracking of result sets. We only do this when mkstemp
+is available (most moderun Unixes supports this). The PID is included
+in filename : tempdir/zrs_PID_XXXXXX.
+
+Added support for specification of staticrank for grs-class of filters.
+This is enabled by using 'staticrank indexname' in .abs. Contents of
+indexname (elm ... indexname:w) is then used as value for staticrank.
+
+Implemented sorting via the ISAMB system. To enable, use sortindex:i in
+zebra.cfg.
+
+Added special retrieval support for sort keys. These keys can also be
+fetched using zebra::index:field:s
+
+Added support for specification of approximative limits for whole query.
+This is specified as attribute type 12. Semantics is the same as
+estimatehits in zebra.cfg.
+
+--- 2.0.6 2006/11/28
+
+Fixed bug #736: Updates gets slower.
+
+Fixed bug #735: Delete fails to process rest of file after a record that
+does not exist,
+
+Added RPM package for Zebra 2.
+
+Improved indexing speed for large documents.
+
+Added support for special utility retrieval zebra:: which offers retrieval
+of fundamental properties for record, such as indexed terms, raw record,
+and system record ID.
+
+--- 2.0.4 2006/10/16
+
+Fixed bug #47: Commit needs to check for roll-back.
+
+Fixed bug #672: Trailing characters in password are ignored
+
+Added extra presence check for tcl.h, because some systems have
+tclConfig.sh installed even though Tcl C headers are missing.
+
+Optimized melm performance.
+
+Do not use sync(2) during commit (but rely on sync'd individual files).
+
+Fixed bug in ISAMB's utility function decode_ptr. With gcc -O3 on some
+platforms the src argument was not updated. Problem was compiler
+optimization due to strict aliasing rules.
+
+--- 2.0.2 2006/09/22
+
+Bug fixes: #638, #647, #657, #669.
+
+Implement skip of 0 hit counts in scan. Useful for scan operations
+limited by a result set.
+
+Honor position attribute, i.e. allow first-in-field search. To
+enable this, "firstinfield 1" must be given for an index in
+default.idx. Enabled in tab/default.idx for w. At this stage
+first-in field is supported for phrase/and-list/or-list searches
+
+Common stream reader interface for record filters (struct ZebraRecStream).
+
+Debian package fix: packages idzebra-2.0 + libidzebra-2.0-modules did
+not depend properly on sub packages.
+
+--- 2.0.0 2006/08/14
+
+New record filter (record type) 'alvis' which uses XSLT transformations
+to drive both indexing as well as retrieval. See example configuration in the
+'example/alvis-oai' directory.
+
+'isamb' is now the default ISAM system. In Zebra 1.3, the default ISAM was
+'isamc'. The type used can still be configured with the 'isam' setting
+in 'zebra.cfg'.
+
+Index structure is now 64-bit based, also on 32 bit systems.
+There are no more 2GB register file limits.
Extended search result tuning. Approximate limit for terms can be enabled
and specified with attribute 11. The (approx or exact) hit count is returned
term hit count can be specified with attribute 10.
Zebra uses string attributes for indexing internally. Using set+numeric
-use attribute can still be used. But that is a search-only conversion which
-inspects .att-set files as indicated using attset-directives in zebra.cfg.
-attset references are no longer required, but when used they deserve
-as "check" for that the index names used are also present in .att.

Zebra record filters (record type handlers) may be built as loadable
modules (.so's) on Unix. In particular the Zebra 2.0 Debian package uses
separate packages for each of them. This also means that zebra programs
such as zebraidx is no longer depending on Tcl/other..
-Documentation updates, especially on queries, SRU, XSLT support.
+Documentation updates, especially on query structure and syntax, SRU,
+XSLT support, alvis filter module, and many added examples.
+
+Improved logging of the 'zebrasrv' and 'zebraidx' binaries.
+
+Improved debian package structure.
