I tried to look up something simple like Package Control to determine if its version 2.x or 3.x installed, but even when browsing the Installed Packages folder, the only thing I could find was a created date of the plugin - created date shouldn't be used for version verification.
Checking out the website: https://packagecontrol.io/channel_v3.json it has a version number as part of the package, setting, but how would a Sublime User retrieve this for an installed package?
I don't imagine if there is any major difference between operating systems, but if you know of anything major (not available in one), please list.
