I'm the author and maintainer of Squashfs and I can assure you that Squashfs is not unmaintained. Over the last couple of years Squashfs has been stable, without requests for new features, and so work have been mostly only security improvements and bug fixes. But there is a big difference between that and claiming Squashfs is unmaintained.
In fact I don't know why you're claiming it is unmaintained. Got an axe to grind perhaps?
I'm not claiming it's unmaintained. I'm saying that the maintainer is not active. You yourself mention elsewhere in this thread that you have little free time to maintain squashfs, so that seems fair.
No axe to grind; it's a cool project and that's why we decided to use it. Thanks for your work on it, and we'll send patches if/when we have them :)
