+ Release Target date: https://en.wikipedia.org/wiki/Equinox
+- Change the release number to 3.X.90 in CMakeLists.txt and sonar-project.properties docs/source/conf.py
+- Deal with deprecations:
+ - Introduce the XBT_ATTRIB_DEPRECATED_v??? macro for the next release.
+ - Kill the one for the current release and remove all code that were
+ mandated by the deprecated functions (both in source and headers).
+ - Do the possible cleanups now that these features are gone.
+- Update the Docker images (after pushing to the git)
+ - cd tools/docker && make stable tuto-s4u push
+
+Release numbering semantic:
+ - 3.X is a named release.
+ - We have 4 named releases per year (for each equinox and solstice)
+ - The ChangeLog and NEWS are complete and informative
+ - All tests pass on all ci systems (or the workarounds are documented)
+ - We provide and store a source .tar.gz and a full jarfile on framagit
+ - Deprecated symbols remain usable for at least 3 named releases (~1 year)
+ - These releases are announced to the users
+ - 3.X.Y is a dot release of 3.X
+ - We provide and store a source .tar.gz and a full jarfile on framagit
+ - These releases are NOT announced publicly, nor really documented.
+ The idea is to have something close to a rolling release.
+ - External projects can depend on dot releases to loosen their
+ release process from ours, when 4 release a year is not enough
+ - 3.X.90 is a git version, a preversion of 3.(X+1) (3.22.90 = pre-3.23)
+ - No expectations on such versions
+
+Doing a dot release:
+ - Update the version number in:
+ - CMakeLists.txt (in macros SIMGRID_VERSION_*)
+ - sonar-project.properties
+ - docs/source/conf.py
+ - Commit and push to both framagit and github
+ - Wait for both appveyor and jenkins/highsierra to complete the build
+ - If it's not successful, fix it and push again
+ - Once it's successful:
+ - tag the release v3_X_Y and push the tag
+ - Merge 'master' into 'stable' and push it to framagit
+ - Do not merge into 'stable' before appveyor and jenkins are done,
+ or your jarfile will not contain the code you expect for win and
+ mac.
