If you don't want your APT-sourced packages to upgrade automatically, I suggest pinning the package.
The apt_preferences(5) man page tells you how to do this. The gist is to add the following lines: Package: cassandra Pin: version 0.6.13 Pin-Priority: 1100 (setting the version to the one you want to install, obviously) to a preferences file sourced by apt. On Ubuntu, just place the above 3 lines in the file /etc/apt/preferences.d/cassandra and you should be set. No matter what happens with the remote APT repository or how you run `apt-get upgrade`, your system will always use the version you specified in the preferences file.

Beta releases should probably be on different channels (or named differently) than stable ones. Better yet would be naming the packages based on the major release in order to prevent an inadvertent upgrade, even once the next release stabilizes. For example, having cassandra-0.7 and cassandra-0.8 would be great, with installation of the latter replacing any cassandra-0.7 package. This is common with PHP and MySQL packages where it's not entirely safe to inadvertently do a major upgrade. Thanks, David
