Active support for MySQL 5.0 and extended support for 4.1 will soon end
By Giuseppe Maxia on Dec 11, 2009
At the end of this year, two long lasting versions of MySQL will fall off the radar, each of them in a different way.
MySQL 5.0 active support will end.
What does that mean? it means that there won't be regular monthly updates and bug fixes. This version enters the extended support period, which lasts until 2012. During this phase, only security and major bugs fixes will be applied.
MySQL 5.0 will still be available in the download pages for two more years, and any security updates will be released on those pages.
The previous version, MySQL 4.1, instead, will be retired completely. It has ended its extended period. As such, it will be removed from the download page, and also from the download archives. Next year, if you want to play with MySQL 4.1 binaries, you will have only two choices: becoming a customer (binaries for all versions are kept forever (or as long as someone uses them) for the MySQL Enterprise users) or build it yourself by extracting the code from the Bazaar archives.(1)
For more information, check the calendar and the fine print at the MySQL lifecycle page.(1) That is not entirely true. There is another way, but I leave it as an exercise to the astute reader.
