The latest released version is 0.94 . We release early and often, so releases may become outdated quickly. Due to limited manpower, we cannot investigate bugs that occur on older release series (such as 0.15.x), unless they also affect the newest supported release or the development version.
Various GNU/Linux distributions provide Pitivi in their repositories, but the version provided may be too old or there might be bugs related to packaging that we have no control over. The recommended way of using and testing Pitivi is through our distro-agnostic bundles below — when reporting bugs, you should test against those, rather than distribution packages.
In order to ease testing across Linux distributions, eliminate dependency problems and allow for quicker testing cycles, we have created a distro-agnostic, all-in-one binary bundle. Our entire stack is bundled, so the only requirement is glibc ≥ 2.13.
Those bundles have been created as part of 2014 Pitivi fundraiser effort; you can get them from the fundraiser page or directly from the download mirror page.
Tarballs of Pitivi's source code are also available on the GNOME downloads page (for packagers, typically), but you should only use that if you really know what you're doing.
Are you super excited to contribute to the development of our next release?
Building Pitivi often means you need to build our whole stack along with it… but fear not! We have documented the process and built tools to make it easy for technically-inclined folks like you to get started. Take a look at the Pitivi GES build instructions (make sure to see the dependencies page first).
Note: if all you want is to test the development version (not play with the code), you should probably be using the "daily" versions of our distro-agnostic bundles instead.
