Regarding release, after Nick Sonneveld set up an automatic build server, and also started to introduce automatic tests, we are discussing to move to a faster release rate (a finalized public release after every big change). With this in mind, there is a number of minor problems to fix, after which we may start a more official "beta test".
I pretty well know that people will worry about other stuff I promised to add (I made too many promises I could not keep in past years :/). But we will start working on these right when we have free time, which may be in parallel with beta test process.
Lastly, I was not mentioning this until now, but I made an agreement with the management in the company I work to switch to half-time schedule roughly in the end of September, which will give me extra time to work on AGS.
