Just to summarize:

1. Ycmd updated, so now we are python 3.12 compatible.
2. New tsserver requires node 14+, but we are saying 18+ because that is the only LTS version.
3. Clangd fixed grammar in diagnostics.
4. JDT reordered some fixits so no we need 3rd one not the 4th.
5. CI is finally green (except for coverage being confused).
