MySQL 5.0.67 will not be uploaded to Debian Lenny

The latest MySQL Community Edition release, 5.0.67 will not be included in Debian Lenny as the distribution is frozen meaning no upstream new releases are going to be included into testing before lenny is released. Lenny will ship with MySQL 5.0.51a, while 5.0.67 (or a newer version if that will be the case) will be added to debian testing right after the release.

In the meantime, if you want to use 5.0.67 you can either download the source packages from MySQL or use the packages Norbert Tretkowski (one of the mysql package maintainers) has made available. The deb sources allow you to recompile the package on any architecture you might need it (only amd64 binary packages are provided).
