Allow merging update-responses from different versions per platform
This is a bit difficult, but Tor Browser 10.0.10 and 10.0.11 is the reasoning behind this. Version 10.0.10 was an update for all platforms, but 10.0.11 was an update for only Windows, and we only built Windows (i686/x86_64) 10.0.11. Therefore, the update response only included Windows, and macOS and Linux users received a message indicating that updating failed and they should reinstall Tor Browser. I fixed this by copying the rewrite rules for 10.0.10 for macOS and Linux into .htaccess of 10.0.11, and now those platforms are receiving the "no-update" response. Automating this would be nice, but I don't immediately see an easy solution.
