The packages of MySQL 5.5.19 are now available for Debian 6.0 “Squeeze” on both amd64 and i386 architectures. They fix some annoying issues that Dotdeb users kindly reported :

  • the mysql-common package, in its 5.5.19+ version, “breaks”  mysql-server-5.1 and mysql-client-5.1 (as APT means it - it won’t actually break your server into pieces). Freezing it will prevent any issue (the introduction of unknown configuration variables in their /etc/mysql/my.cnf, for example)
  • the MySQL client now uses the system’s readline library instead of the bundled editline wrapper
  • missing header files and libraries are now included in the appropriate packages

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