The packages of MySQL 5.5.20 are now available for Debian 6.0 “Squeeze” on both amd64 and i386 architectures, with the following changes :

  • the mysql-common package should now work with MySQL 5.1 packages without any problem (unknown configuration variables in /etc/mysql/my.cnf have been commented out)
  • mysql-server-5.5 now supports Linux native asynchronous IO

As usual, please read the full Changelog carefully before upgrading.
