Realized I need to add a minimum version requirement to an extension. How can I easily determine what that requirement is?

The extension makes use tab permissions, as well as a popup browser action, but I'm not clear on (and have not been able to find) when those features were added.

Any suggestions? Any resources I could use for this, other than sifting through tons of changelogs?

Probably doesn't matter right now without being able to add a minimum version to the manifest.json, but it would be helpful for future api updates.

extensions are only supported in the dev version of Chrome at the moment

Minimum browser version

To ensure that a given extension update will apply only to Google Chrome versions at or higher than a specific version, you would add the prodversionmin parameter to the <app> tag in your update manifest.

PHP Code:

<?xml version='1.0' encoding='UTF-8'?>
<gupdate xmlns='http://www.google.com/update2/response' protocol='2.0'>
  <app appid='aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'>
    <updatecheck codebase='http://myhost.com/mytestextension/mte_v2.crx' version='2.0' prodversionmin='3.0.193.0'/>
  </app>
</gupdate>

This would ensure that users of this extension would autoupdate to version 2 only if they are running Google Chrome 3.0.193.0 or greater.

See Autoupdate

So... right now, you could create a "UPGRADE YOUR BROWSER!" extension popup. (extension version 1.0) In its manifest you could put up the above auto-update snipplet
