Any idea when 2.2 will be defined/released?

[Hans Forbrich]

Any idea what new features & capabilities are being planned before 2.2 is 
released or what time frame 2.2 is expected.

I have seen some amazing advances in Lilypond lately and I'm itching to use 
the new features, syntax and capabilities in 'production'.  In my case, 
production is reproducing  a 400+ page out-of-copyright book (published in 
1882) that is rapidly decaying.  I will be starting with the individual songs 
using Lilypond 2.1.x, I hope to avoid returning to all the older pieces for 
upgrades on completion.
