I made an announce of Cupt. It resulted in some new people trying & testing & reporting bugs, plus several Linux/Unix-related sites picked up the announce and formed a news entry from it. And a bit sadly, though fully expectedly, most of comments played implementation language holy war.
Since first beta was uploaded, I have some time to perform usual round of optimization, and it appeared to be quite productive this time. Several minor optimizations were simple enough to go directly to master branch. With a usual bunch of bug fixes, they formed just uploaded first release candidate. Another few of them are more complex, so they live in various branches and, presumably, will be a part of Cupt 1.1 after some testing.
