MySQL users,

Sorry for spamming mysql@lists.mysql.com, but you may be interested in
my blog entry that complements our MySQL 5.1.22 announcement.

MySQL 5.1.22 is out

A good two weeks ago, MySQL 5.1.22 was released. MySQL 5.1 is a new
release of MySQL Server, with new features like

* partitioning (likely the top feature in 5.1)
* events (”crontab” triggers in the database)
* row-based replication
* table logs
* some XML functions

and also with major bug fixes, such as the AUTO_INCREMENT table-lock
contention in InnoDB (fixed now in 5.1.22), as well as early indications
of performance improvements of up to 20 % - 40 % on dual cores in some
scenarios.

Jay Pipes has written an overview that compresses all of the pointers to
5.1 into one article, MySQL 5.1 Article Recap. I recommend you read it.
I also recommend the manual section What’s New in MySQL 5.1.

With 5.1.22, MySQL also changed the maturity state to “RC”, Release
Candidate. Looking at our own Support Policies, Release Candidate (aka
Gamma) release is defined as follows:

Release Candidate binaries, also known as Gamma releases, are believed
stable, having passed all of MySQL’s internal testing, and with all
known fatal runtime bugs fixed. However this release has not been in
widespread use long enough to know for sure that all bugs have been
identified.

However, we recognise that this particular RC does not fit the
definition exactly. We still have some fatal runtime bugs left. We are
producing an errata list of these, and expect to have the list ready and
published on by 23 Oct 2007. We know that we should have published this
list together with the RC itself, and we are now working as fast as we
can to fix this.

We know we have thus released our RC too early according to our own
standards, and we are doing our best to fix it. We apologise for any
inconvenience/miscommunication and are working on improving our internal
guidelines to ensure it doesn’t happen again.

That said, 5.1.22 is a great release, one that we’re proud of, and very
likely worthy of your attention!

Is there any kind of timetable for when 5.1 is actually expected to be
released?

Hi Jim, all !

Sorry, no - there cannot be any firm "expectation" yet, and consequently
no "timetable".
Different people have different *hopes* when that may be, but these
personal estimates will be made concrete only by facts and experiences.

Consider the following parts of Kaj's blog / mail you quoted:

>>
>> [[...]] We still have some fatal runtime bugs left. We are
>> producing an errata list of these, and expect to have the list ready and
>> published on by 23 Oct 2007. [[...]]

Only when this list is available and all its elements have been judged,
we will have a full (but only momentary) overview of what still needs to
be done.

>>

>> likely worthy of your attention!

So for the MySQL development to bring 5.1 to a true "GA" status, we
really need and appreciate your help and feedback,
be it bug reports (we sure hope only few ones, but who knows ?)
or (positive ?) messages like
"I used feature X with the Y amount of data and Z of
users/transactions and had these experiences: ...".
Regardless of how much we improve and strengthen our own QA, it will
never be able to fully mimic the ideas/workload/diversity of our users.

Any such feedback, be it negative or (hopefully !) positive, will make
that overview more exact and complete.


Regards,
Joerg
