As of gh-112661, the threading module expects the _thread module to have a _is_main_interpreter(), which is used in the internal threading._shutdown().  This change causes a problem for anyone that replaces the _thread module with a custom one (only if they don't provide _is_main_interpreter()).  They need to be sure to add it for 3.13+, thus this PR is adding a note in "What's New".

This also forward-ports the "What's New" entry from 3.12 (gh-112850).  Note that we do not also forward-port the fix in that PR.  The fix is there only due to a regression from 3.12.0. There is no regression in 3.13+.

Previously arbitrary errors could be cleared during formatting error
messages for ImportError or AttributeError for modules. Now all
unexpected errors are reported.

3.12 as the base implementation for import from. This meant that I
