It is currently not possible: 1) To get information about the recent changes in an extension, except for going to the extension's homepage (and even there, the changes are not always present) 2) To know, which version of an extension gets updated to the recent one. For example, the Update window only tells about "WeatherFox can get updated to 0.6.0", but no information about which version is current is present (could be looked up in the extension manager before installing the upgrade, but it's inconvinient). Would be nice, if an extension author could insert his recent changelog into the extension, which would get shown in the Update window if desired.

Changlog is available from update.mozilla.org assuming the author puts them in.

Definitely would be a nice improvements to include changes as part of the xpi, or some such, and show them in the Firefox Update dialog. It's always kind of anticlimatic to download a bunch of updates and not know what's new.

What would be the best solution to this problem? Add a optional changelog.xml file in the xpi with a structure like: <?xml version='1.0' encoding='UTF-8' ?> <changelogs version='1.0'> <changelog> <version>1.0</version> <name>Mighty version!</name> <description>First no beta version!</description> <changes> <change type='added'>Flying mode<change> <change type='changed'>Pig harvesting now on by default<change> <change type='fixed'>Buffer overflow in the arsenic dispenser<change> </changes> </changelog> <changelog> ... </changelog> </changelogs>

Essentially the same as bug 297903

I believe this was fixed by bug 297903, authors can now provide a change history visible when a user sees an update notification.
