Quoting the changelog:

[log] SoundRTS 1.1 beta 0 released

Available at:
http://jlpo.free.fr/soundrts

This is a beta version of 1.1 which will replace 1.0 as soon as possible.

The main changes since 1.1 alpha 9 are:

General:
- this is now a "test" version instead of an "unstable" one
- bug fixed: when playing a restored game, the action menus wouldn't work (unless a new game has been played during the same session)
- bug fixed: with a screen reader, official map names would be unreadable symbols
- bug fixed: when moving the cursor from a square to another through a known path, the screen reader would say "blank" (or something representing an empty string) before the name of the new square
- when a flying transport is destroyed, the transported units will die and their corpses will be on the ground
- when a ground transport is destroyed, the transported units will just exit from the transport
- replaced teleportation with recall
- will say "train 10 peasants" instead of saying "train peasant" 10 times
- removed or lightened some of the punctuation

Translation:
- added German version of tts.txt (allows direct use of SAPI or screen reader)

Modding:
- modding guide updated: recall and teleportation
- in style.txt, "if_me" doesn't require "else" anymore

SoundRTS 1.1 and SoundRTS 1.0 should coexist in the same machine without any problem. The settings are also stored in different folders (respectively "SoundRTS test" and "SoundRTS 1.0").

About multiplayer games, this version is only compatible with itself. If you modify the rules.txt file or the ai.txt file, you need to send it to your friends if you want to play with them, or they won't find your server.

I'm particularly happy about the bug fix for the unreadable map, that was driving me nuts.
