Vim 7.3b ready for beta testing
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
