https://github.com/nim-lang/Nim/pull/19403 should fix the failure of Nim doc CI.

Here is the draft of "Migration to ORC", I'm adding add issues and solutions of ORC => https://github.com/nim-lang/Nim/issues/20017

macos CI is broken, see https://github.com/actions/virtual-environments/issues/5583 and my fix https://github.com/nim-lang/Nim/pull/20098

Note to myself: it is weird that threads tests failed on Linux i386. Test it with another PR in the future.

[nim-chronos](https://github.com/status-im/nim-chronos) has already been taken care of => https://github.com/status-im/nim-chronos/pull/300

docs now built with the ORC booting compiler

The mega tests are a mess, I have to clean up the echo in tests first.

Anyway kept here => https://gist.github.com/ringabout/aa8cf0dca8839188bd43e1c9ca35dae4

There is something wrong with tests\template\twrongmapit.nim. After disabling it, there are tons of errors for megatest.

`shallowCopy`: made a PR for karax https://github.com/karaxnim/karax/pull/230
