Hi All,

I have released PrimeBase XT (PBXT) 1.0.03 Alpha and it is available
for download from http://www.primebase.org/download.

I have also posted binary plugins for a few platforms, in particular:
32-bit and 64-bit Linux and Mac OS X (x86). These plugins can be
loaded at runtime by the corresponding MySQL binary distributions.

If you are building PBXT yourself I have added a "Quick Guide:
Building and Installing PBXT from Source", to the download page which
should make it as easy as possible.

With this version I have completed the implementation of full-
durability, and other features that are scheduled for RC and
ultimately for the first GA release. Still to be done is the Windows
port which I plan to do before the first Beta release.

PBXT is a transactional storage engine for MySQL. Features include:

* MVCC: Multi-version concurrency control, enables reading without
locking.
* Transactions: support for BEGIN, COMMIT and ROLLBACK and recovery on
startup.
* ACID compliant: Atomic, Consistent, Isolated, Durable (once
committed changes cannot be lost).
* Row-level locking: updates use row-level locking allowing for
maximum concurrency.
* Deadlock detection: immediate notification if client processes are
deadlocked.
* Referential Integrity: foreign key support.
* Write-once: PBXT avoids double-writes by using a log-based
architecture.
* BLOB streaming: In combination with the BLOB Streaming engine (http://www.blobstreaming.org
).

PBXT is open source and is available under the GPL license. For more
information please go to: http://www.primebase.org, or contact me
directly.

Best regards,

Paul
