Release/v4.0.0 rc.2

[peaBerberian]

v4.0.0-rc.2 (2024-02-07)

Overview

The rc.1 seemed pretty stable, yet we had some issues with our MULTI_THREAD experimental feature on some older TV that we would prefer to fix for the v4.0.0 (explained in #1372) so that everyone could test that new shiny feature with confidence at the official release (even if it will stay "experimental" to let us update its API if needed).
So here comes a rc2!

Other changes are a small fix in UTCTiming handling (that we also have to fix in v3), doc updates and updates to simplify our building script. So from what we've seen that's a good sign for the evaluated stability of the v4.
