The SVN-message for 8744 says:

"Voice Taunts update: changed civgroup name format, to allow using civgroups with 3 digits numbers."

Has this an effect on used number of digits for existing civgroups? Like in, will civgroup 67 need to be renamed to 067 to be known by game?
Do I have to change existing digits (...098,099) or will this just allow me to use more then 100 civgroups (...,98,99,100,101,...) ?

Voice taunts can be played for enemy team, militia team and civilians which have civilian group, so the folder structure looks like this:
Data\VoiceTaunts\Army\
Data\VoiceTaunts\Militia\
Data\VoiceTaunts\CivgroupX
I haven't found the Folder Data\VoiceTaunts in GameDir 2513. So I understand that I either use the download you mentioned (which contains the file-structure),additionaly,
or have to create them myself to make use of this feature. Is this correct?

It most likely is completly unrelated, but I lack the knowledge so I better ask:

(out of overhead.lua and strateticmap.lua)

" -- We have an array of 1000 signed integers that a modder can use to set whatever data he wants.
-- We simply set up some enums here to make it easier for us to remember what is what

ModSpecificFacts = "

I used that a lot and now I'm worrying, if the "array bonds" in the quote might be affect the array
for ModSpecificFacts as well? Kinda doubt it will, but the woorywart in me insists on asking.

Added new options:
ENABLE_TA enables fire ambient sound
VOLUME_TA controls fire ambient sound volume
When I've seen this, I couldn't help to ask myself if there is a slim hope that SSA might also be included in trunk?
