An exchange has technical issues. There is nothing to inform about but to say that we will support them if they ask for support.
We can't do the work the exchanges have to do so we can't give an ETA.
Please do not mix third party issues with dev work.
About this - "we stopped the tradind on all exchanges" (Telegram group). Now you say that the developers also know nothing about the suspension of trading and it's all bad exchanges?) To inform us the developers also did not consider it necessary? Clearly there are problems that no one wants to comment on. And this "code rebase" does not justify what is happening. Such things are planned in advance and the community is informed.
