Yesterday was the surprise announcement of MySQL 5.4 at the 2009 MySQL Conference and Expo. It was unfortunate that the supporting information was not that forthcoming on the MySQL website. I tried for several hours to try and download, but no mirrors were initially available. Today I see some information on the mysql.com home page and finally able to get the binary.

What I found most significant with this new major version release is a change in the binary distribution, as seen on the Download page.

MySQL 5.4 is only available on 3 platforms:

• Linux (AMD64 / Intel EM64T)
• Solaris 10 (SPARC, 64-bit)
• Solaris 10 (AMD64 / Intel EM64T, 64-bit)

I was also surprised that this beta release highlights the emphasis of community contributions (long overdue), yet the community and indeed many employees of Sun/MySQL were simply unaware of this work. This is clearly a change in involving the community. While I applaud the beta status, hopefully a more stable product to start with, it’s development was done in a very closed company model.
