Congratulations to the Debian team for releasing Debian GNU/Linux 5.0 Lenny on Valentine’s Day. This version comes with MySQL 5.0.51a.
I had been pestering Norbert Tretkowski to see when MySQL 5.1 will move from experimental to main, and he told me once Lenny was released. This is because Debian itself needs to make a library transition from libmysqlclient15 to libmysqlclient16, and every package that links to libmysqlclient will need to rebuild against the new version. It couldn’t be done any earlier, and now that Lenny is released, we should start seeing MySQL 5.1 in Debian/unstable, real soon now.
So, if you’re a Debian user, know that you have 5.0.51a in stable (Lenny), 5.0.75 in unstable, and 5.1.31 in experimental.
