Audacity 1.2.4 is a new stable version of Audacity.
It includes a couple of bug fixes and minor improvements and is recommended for all users.

Audacity 1.3.0 is a beta release that contains hundreds of new features, but this version is unfinished and unstable, and is recommended primarily for advanced users. You can install both Audacity 1.2 and 1.3 simultaneously.
