This is a feature and bug fix release which has been tested on the
following platforms:

Release notes:
--------------
1) This release greatly improves upon SQLite concurrency. We have
tested libzdb with SQLite using up to 300 concurrent threads without
experiencing lock problems. To achieve this, we use the experimental
SQLite unlock notification API. To enable this API you need to first
build and configure SQLite (version > 3.6.12) with the
SQLITE_ENABLE_UNLOCK_NOTIFY preprocessor symbol like so:
CFLAGS="$CFLAGS -DSQLITE_ENABLE_UNLOCK_NOTIFY" ./configure ...
Then you need to enable this API in libzdb using the --enable-
sqliteunlock configure switch when configuring and building libzdb.
2) For those using libzdb with the excellent DBMail (http://www.dbmail.org/
) project it is strongly recommended to upgrade. This version of
libzdb is tested by the DBMail project and should work with the latest
DBMail release.
Changes in this release:
------------------------
* Internal optimizing changes and improvements
* Enable shared cache mode for SQLite >= 3.5
* Added new configure option --enable-sqliteunlock which
enables SQLite unlock notification. This feature requires
SQLite >= 3.6.12 compiled with the SQLITE_ENABLE_UNLOCK_NOTIFY
C-preprocessor symbol. This option greately improves upon
SQLite concurrency when libzdb and SQLite is used from a
multi-threaded program.
* Removed deprecated ResultSet_readData() from API
Bug fixes:
* PostgreSQL: Unescape values retrieved via ResultSet_getBlob()
and via ResultSet_getBlobByName(). By an incurie, unescape was
left out of libzdb version 2.5.
