Is v1.13.0 still the latest official release?
I looked at the "Installation Mirror" topic. However, it seems the vast majority of links there are broken (all except Mega, Google Drive and Mediafire, though I haven't tried the torrents). And the version numbers mentioned there mostly seem obsolete, too. Indeed, there's not a single post made there that's newer than 2020. And only one post has been updated in 2021 (none in 2022). I also get confused how there seems to be a separate 1.5x branch and a 1.9x branch that are labelled as "obsolete" - this, despite how, from a mathematical viewpoint, both "1.51" and "1.95" should be considered higher and more recent than, say, "1.13"...
Further:
Despite how the last update to the OP (#1 post) was over a year ago today, I've noticed on the GitHub or GitLab for certain C# utilities such as "Aurora Government Simulator". For example, I see "Bump version to 1.99.0.4" as a note for the commit published just yesterday, with a trail of mentions for 1.99 that goes back at least 3 or 4 weeks.
Is version 1.99.x an internal branch only available to beta testers?
