Бета и ночные сборки
Нестабильные бета-версии
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.
Ночные сборки
Разработка WordPress происходит достаточно быстро и день ото дня что-то ломается и исправляется. Это часть нашего процесса разработки, для выпуска по возможности максимально стабильных выпусков.
If you would like to be part of this process, the best place to start is the Beta Testing Handbook.
