Choose your version

The Linux-VServer project maintains several branches of the kernel patch. Since version 1.00 the versioning is similar to the kernel versioning scheme. Even numbered releases (a.X.z with even X) are stable, reasonably well tested and expected not to change feature-wise. Odd numbered (a.Y.z with odd Y) releases are development releases. The last digit/number (z) is a subversion identifier. Experimental versions and Release Candidates might add a fourth identifier to that scheme.

Basically the stable and development releases should be similar in functionality, but the development releases will include features and enhancements not present in the stable branch. Once those features mature (and get well tested), they will be incorporated by the stable branch.

For example the first stable release (1.00) uses two systemcalls as the previous releases did. However, the vserver system calls have been changed in the first development release (1.1.0). Linus assigned the vserver project a single system call, so a [System Call Switch] has been implemented. Running a development release usually requires using recent (latest) tools from the util-vserver development branch.

1.X.z and 1.Y.z releases are for the 2.4 kernels, while 1.9.x (obsoleted by now) and 2.X.y releases are for the 2.6 series.
