For example:
outdated 0.13 mod: https://mods.factorio.com/api/downloads ... _1.0.0.zip
Installing this on a 0.13.19 client and then using "Check for updates" in the mod screen doesn't show the available update.
Deleting the mod and then installing it via the mod browser installs the latest version for 0.13.
Edit: Seems like HanziQ is already aware of that
