Hello,

We are pleased to announce the availability of the phpBB3 Beta1 package. With this first beta release we are officially starting the beta testing phase. Below are some guidelines regarding the first beta as well as the download locations.

Obtaining Support

During the beta phase a minimal level of support will be given. We will provide answers to general setup questions, configuration problems and support for determining common problems mostly related to bugs. We will not support modifications, custom code/style additions or any users using the beta packages within a live environment.

For some support questions we may ask you to re-install the beta, clean tables in the database, purge data or other actions which are not advised to do in a live environment. So please be aware that you are still on your own if you run the beta in such an environment.

Beginning with the release candidates full support will of course be given.
