• Removed around 3K unneeded and old branches from the repo, only about 10-20 are left. Probably some of them are unneeded too, but it's not easy to decide.
• Some progress with stdlib (PR). Now testing uses newly copied stdlib-py. I've checked, indeed when stdlib-py is edited, we have the changes applied to the files compiled under testing. However, compilation of a separate jar isn't implemented yet, so these changes can't be used with kotlinc.
• Want to support jar too. After it, I believe we can close the ticket about stdlib-py.
