MySQL 5.1.24 was released last week. I am nearly done with preparing and testing the updated package for Debian, and will upload it to experimental within the next few days. MySQL AB decided to disable Cluster support from their official binaries with 5.1.24, but unfortunately they forgot to add a note to the release notes. It was only mentioned in a bugreport where someone asked why mysqld does no longer understand the --ndbcluster option in 5.1.24:

It was decided that we do not support NDB Cluster in the 5.1 release but do a general release of the Carrier Grade Edition 6.2 branch (which is based on MySQL 5.1) instead as it has received substantial improvements on the cluster side that can not be backported to 5.1 for now.

So while the 5.1.24 source still includes the cluster storage it is not built into the binaries released by us. A MySQL Cluster 6.2.x binary release is expected to be become available before end of April.

I am still thinking about how we should handle the new situation in Debian, hence I will keep Cluster support enabled at least for the first 5.1.24 upload. Maybe we will see a separate mysql-cluster (or mysql-cge) package in Debian soon...

Update: The information about changed Cluster packaging was added to the release notes.

MySQL 5.1 and up supports a plugin interface that allows the loading and unloading of server components at runtime, without restarting the server. Today I started working on a mysql-storage-engines package for MySQL 5.1 in Debian, which includes the PrimeBase XT and Sphinx storage engines. I currently do not plan to create separate binary packages (like mysql-engine-pbxt and mysql-engine-sphinx) for every single plugin.

Suggestions for additional plugins which should be added are welcome.
