@casimiro Caio, would you mind drafting a PR that takes both @hishamhm's work in #486 and the bits from this PR? Instead of merging #486 and then rebasing this, rather rebasing this PR atop #486. I think name: release-artifacts-${{ github.job }} is a good template for all these artifacts names (combining both of your ideas). This PR also has the unit/valgrind uploads fixed and some other version bumps. Let's combine it all and enable the release job temporarily in release.yml to test it.
