If you missed Kaj's announcement in the splashing news commotion at the latest MySQL Conference, then you may be interested to get this information again.
There was a piece of news that should be extremely important for all the users. MySQL server binaries used to be split between Enterprise and Community, and they were released with separate schedules. Not anymore. Starting from April 2009, the MySQL Community and Enterprise editions are built from the same code, and they are released with the same frequency.
There were rumors about the two editions being treated differently. Since we are talking about it, let me assure you that this is not the case. Both editions go through the same tests, and even more so now, since they come from the same tree. Until version 5.0.81, there was a separate tree for Community (with extra features), but now there is only one.
For every bug fix release, both editions are released on the same day.
Another difference that has disappeared is the version number. Previously, even numbers were for Enterprise, odd ones for Community. Now, every version number identifies both the Community and Enterprise edition.
