MySQL 5.5 is now in RC, and will be GA soon!

Earlier this year, the beta of MySQL 5.5 was announced.  We all felt excited about the changes in 5.5, especially the large performance improvements.  However, many of us proceeded with caution; version 5.4 was previously announced with similar fanfare and we had yet to see a GA version.

Well, Oracle has indeed put its money where its mouth is.  In the MySQL Sunday keynote today, Thomas Ulian (VP of Product Development for MySQL) announced a release candidate version of MySQL 5.5 and said that a GA release of 5.5 was coming soon (maybe by the end of the year?).

Oracle promised that they will continue to improve MySQL and invest more time and money than Sun did.  Throughout the past 6 months we have seen this happen in significant but small ways -- MySQL had monthly releases before the Oracle acquisition, but the number and quality of fixes has increased.  This was noted as recently as a month ago in a blog post by Percona's Baron Schwartz and Facebook's Mark Callaghan confirmed his opinion in a comment on that post.

As Oracle ACE Directors, Ronald and I were privileged to hear all the upcoming Oracle OpenWorld and JavaOne announcements ahead of time.  Though we heard a lot of exciting stuff, MySQL was not mentioned, so we were not briefed ahead of time about this announcement.


it is exciting to hear this news,when the GA comes,we can use it in our product

Henrik -- I haven't asked that, but either way, it's good -- either it's new names, and thus fresh blood, or it's getting the remaining developers more productive.

Probably you should go look into the bzr commits and figure that out for yourself. I don't know that I'd recognize all the developers that are new vs. old, but you likely would.

Hmm... is this the appropriate place to congratulate Tomas for his promotion! (...or perhaps I need to actually send an SMS :-)Anyway, do we have any info on where the increased bug fixing rate comes from? Looking from the outside - which is people we know and that can be seen in blogs - I only know that developers have left. Not alarmingly many but still a significant group. If I went and looked into bzr commits, would I see lots of new names in the MySQL team (recruited or internally transfered at Oracle)? Or are the remaining devs just being more productive with Tomas bossing them, producing more for less?

It was confirmed yesterday that 5.5 will be GA before the end of the year. I guess we don't have to wait very long to find out.

I hope you are correct about the GA release comming soon. And I just hope they don't drop the new features I need before the GA.
