I’m trying to release it this month, but given the amount of work, it might bleed into next month. That means there’s not much room for big new features, but there is for bug fixes. If you know more information about any of the bugs you mentioned, please post it in the bug tracker.
The lens flare effect looks cool. If someone finds a way to integrate this into CommonFilters.py, I’d be happy to ship it. Have you asked ninth about the license it is under, and/or whether or not we’d be allowed to include it as part of Panda?
As for hair simulation: it sounds a bit specific to be included in a general-purpose library like Panda, but if the extension is well-written and if it’s interesting to enough people for it to be of general use, I’d be happy to include it as a contributed module.
