 ## Releasing the library

-Because of the incompatibility of the play-json module between version 2.3 and 2.4, a different branch has been created.
-Each change that has been merged into ````main```` MUST be merged into the ````play-2.4```` branch
-
-Once this is done, make sure to run ````sbt release```` on both branches

-NB: As the main branch is protected, we cannot push directly from main, so we need to do this through a development branch (create a PR).
