Gatling git version tags

I wondered that the list of tags (“git tag”) does stop with “v2.2.0-M3”.

Is there any known reason ?

We stopped using sbt-release plugin that was way too buggy and was frequently causing our releases to fail, but was creating those tags.
Tags are just git commit aliases, so they’re not that useful as you can easily find the release commits in the history.
Moreover,Gatling is in Scala, so Github’s releases (that are mere tagged repository downloads) are completely useless (you can’t run them like dynamic languages a la javascript, ruby or python).
