Addons have to include a label to tell the game which version they're compatible with. They're marked as out of date if that doesn't match the current version of the game, and will only change if the author (or someone else) manually updates that version label.

However it doesn't mean the addon won't work, it's very rare that an update affects all addons and some can go for years without being updated and still work, it depends on what they do and what changes the game gets.

Some addon authors will always keep the version note up to date regardless of if anything else changes (with some addons you'll see the patch notes for most updates are just about this), others won't do an update unless they actually need to change something. Some addons are abandoned and won't get updated at all.

I don't know what specifically if going on with the ones you listed, but if you can't find a newer version it's likely there isn't one and unless the addon isn't working I don't think there's any need to worry about that.
