Comment:

 > Yet on August 18, 2018 7.5.5 was still included in
 RecommendedTBBVersions. Why? Forgotten or is there a policy to it?

 Sorry, it should have been removed a few hours after `7.5.6` was released,
 but it was forgotten. I have removed it now.

 > Could you please kindly explain the policy on when old versions are
 removed from RecommendedTBBVersions?

 When a new version fixing some security issues is released, we remove the
 old one from `RecommendedTBBVersions`, after 12-24h to give time for
 people to update before showing a warning. When the new version is not a
 security update, we keep both versions in `RecommendedTBBVersions`.

 > I am asking, so ​tb-updater parsing code can be updated accordingly. (At
 the moment it's "suggest the lowest version number among them otherwise it
 might be an alpha/beta version".)

 A more reliable way to find what is the current version is to look at
 `appVersion` in this URL (if you can parse xml):
 https://aus1.torproject.org/torbrowser/update_3/release/Linux_x86_64-gcc3/x
 /en-US

 Or `version` in this one:
 https://aus1.torproject.org/torbrowser/update_3/release/downloads.json
