Sorry for my late reply.
I am working on the new version ASA 2 right now and I guess it will be ready in the first quarter of 2015. Hopefully I can start a beta test in 2014.
ASA 2 aims to solve every inconvenience ASA 1 has. It has a very powerful template syntax featuring conditions, loop, placeholder filters etc. You will love it! The templates are stored in the database, so no losses on updates anymore. Of course there will be caching, but more reliable and with some pro options, like using different storing types (memcache etc). And there will be some other great improvement I will not reveal yet and here, but I already love ASA 2 for its flexibility (it’s way more flexible than ASA 1!)
As there will be a premium version (I’ve been working on ASA 1 and 2 for years ;-)) I am not planning to use github yet, but let’s see what the future brings. Maybe I will put the lite version (the basis) of ASA 2 to github.
