Beta 3 is a minor bug fix release:
- Fixed a NilObjectException when loading data into the main window.
- Fixed a NilObjectException when checking the free space.
- Searching for a MailTags colors gives a result again.
- The session logs no longer grows so large.
A couple of bugs are still in progress - as usual. However, when no new major bug will be found then I'm going to release the final version of 5.2.0.
