Beta/Nightly
Versions bétas instables
If you are comfortable with PHP and would like to participate in the testing portion of our development cycle and report bugs you find, beta releases might be for you.
By their nature these releases are unstable and should not be used any place where your data is important. Please backup your database before upgrading to a beta release. To hear about the latest beta releases your best bet is to watch the development blog and the beta forum.
You can find the latest beta releases on the Beta Releases page.
Versions Nightly
Le développement de WordPress est très dynamique et quotidiennement, les choses se cassent aussi vite qu’elles se corrigent. Ce rythme effréné est une part importante de notre processus de développement dont le but est de produire les versions les plus stables possibles.
If you would like to be part of this process, the best place to start is the Beta Testing Handbook.
