I've thought about how to do it properly and decided that short summaries will be posted here, and most development posts will be in separate channel.
So the first thing is, here is new channel: https://t.me/kotatogram_dev
I've started with attempt to update patches-track-4.8.4 branch to 4.14. Suprisingly, it took less time than I expected, so I've built the new test version, taking a little of 4.14.1 and some commits after it. Note that bugs aren't fixed there, but it supports everything TDesktop 4.14 have.
That's all for today, other things will be soon.
