Apparently the 0.9.9 release went very well. We didn't discover any severe (functional) bugs yet, but thanks to reports on the mailing list and in our
forum, which seems to be pretty well accepted by now, we spotted some bugs and problems. Since 0.9.9 is maintained (in opposite to 0.9.8 ) we now
released 0.9.9.1 which includes all those fixes. This time we also tracked
the changes 
Please note that an important security issue has also been discovered (thanks again to
Stefan Esser) and fixed, thus we urge you to upgrade to the new version in your own interest
The release took a while longer than intended because of a server outage. The reason was our own Flyspray. What happened? One problem was (or rather still is) a bug (or, until we know more a
change) in PHP 5.2.1 which causes problems with Jabber connections and made our server have (too) many unclosed connections, another problem were really slow queries in Flyspray. Our own Flyspray did in fact never get a correct database upgrade (I'd say due to the laziness of the previous maintainer ^^) so many important indices were missing which resulted in a lot of work for our SQL server.
BTW, if you are interested in always having the most stable version of Flyspray, you can safely use the latest code from our SVN repository (branches/0.9.9/) which is the basis for new bug fix releases, you don't have to wait for new releases.
If you are interested in new features, you should try the current trunk. In particular
FS#218 is done, which adds the possibility to add and delete custom fields. The upgrader also got some improvements, so this time you probably will not have to fear that you can't upgrade your development version anymore when you don't remember the revision number. It should now be able to upgrade
from any revision
to any version.
Themes again: Recently Flyspray got the first 0.9.9 compatible
custom theme! Tristan made a
"high density" theme:
A short while after that, we also got
an update of the "clean theme" from Paul.
I'll use this as occasion to once again point out that we need someone who creates a fabulous new theme for 1.0

If no one offers to do this, we might start a design contest with a higher reward...so if you got curious check
FS#937.
So what is the schedule for 1.0? Well, there is none - at least no dates. We have a
TODO list with lots of stuff on it, but we still have some other tasks to tackle for 1.0. It will probably take a while...maybe even a year or longer again (all depends on how many new developers join), but as mentioned earlier 0.9.9 will be maintained during that time.
On a side note: this post has been drafted on Feb 26th, so you can see how much longer the release took...
