Changelog generator should allow merging two or more versions
The script used to generate the changelog for releases should allow merging two or more versions.For example, for the latest releases, we generated the changelog for two versions:
The changelog for 4.2.2 should contain also the changes for 4.1.4, but the script doesn't do this and we need to manually merge the changelogs which is very error-prone.
Also, the script should allow authorised requests in order to pull the security issues which are private at the time of the releases. The authorization should use environment variables.
