Very useful add-on! Rated 4 out of 5 stars

Improves Thunderbird immeasurably!

A new version was just downloaded, however, and I don't see any information anywhere about what has changed. Am I missing it?

This review is for a previous version of the add-on (2.6). 

Hi, see https://addons.mozilla.org/en-US/thunderbird/addon/gmail-conversation-view/ near the bottom there is a section "version information"
