We know beta 4 has lots of issues, most of all, the path-finding is crap.
Here is a bit of a explanation.
The current release candidate 2.1, means that you can't use your old beta 4 savegames. This can be a big issue to some.
2.1 will not have FMVs.
2.1 does (should) fix the bad path-finding in 2.1 beta 4.
On the other hand, we could skip 2.1, and just go to 2.2.
All the fixes in 2.1 (since beta 4) are in 2.2 also.
2.2 savegames are the same format as 2.1 b4.
2.2 will have FMVs*.
2.2 will also have other enhancements.
(edit) releasing 2.2 will take longer to release than 2.1 (as the release cycle will have to start over again)
The only other problem with 2.2, is some of the features it has are untested by a wide pool of testers, so we may run into unforeseen issues.
In either case, there is going to be another beta, but if the beta is from 2.1 or 2.2, that is what I am attempting to find out.
So Vote NOW!
*on linux & windows at least, but we have no testing on macs yet!
p.s, sorry about the poll before, had to correct a few things.
