Hello Vim users,

Announcing:  Vim (Vi IMproved) version 7.3b BETA

This is a BETA release of Vim 7.3.  It consists of Vim 7.2 plus all
patches, updated runtime files and some more.

7.3b both includes lots of fixes and a few new features.  Everything
needs to be tested to verify no new problems have been introduced.

Please report every problem you find!  The time until a 7.3 release
depends on how many problems are reported.

The biggest additions since 7.2:
- Persistent undo, undo for reload
- Blowfish encryption, also encrypt the swap file
- Conceal text (note: since 7.3a ‘conc’ was renamed to ‘cole’)
- Lua interface
- Python 3 interface
