Instructions on how to release

[tpolecat]

Would it be possible to include "update the dotty-repl Coursier app definition" in this list as well?

[nicolasstucki]

The instructions link is outdated. Here is the new one https://dotty.epfl.ch/docs/contributing/procedures/release.html
We need to update it in the release todo instructions template.

[nicolasstucki]

We are also missing https://github.com/scala/scala3-tasty-inspector.g8

[nicolasstucki]

@anatoliykmetyuk where did you get the todo list from? docs/docs/contributing/checklist.sh seems to be quite outdated.

[nicolasstucki]

@anatoliykmetyuk I've updated the links in the first comment. Could you sync those with the template?

[anatoliykmetyuk]

@nicolasstucki all the release scripts are located at https://github.com/lampepfl/dotty-release-scripts. I updated the checklist: lampepfl/dotty-release-scripts@a32d995

@tpolecat done.
