Warning: This is a pre-release (alpha) for beta testers only. This 
release is *not* for use in production.
This release should be treated with similar caution as the daily 
snapshots. It may contain serious bugs.

For day to day and production use please download a Lazarus 1.0.x (e.g. 
Lazarus 1.0.12) release. You can find this in the parent folder.

If you wish to participate in the early testing, you should be prepared  
to backup and restore your data.
If you do not feel experienced enough, please wait for the first release 
candidate in a couple of weeks. You can still join the testing then.

Please also see our pre-release announcement on our forum.

Select zip or tar.gz.
