| I've noticed that many of the linux repos are not up to date. If you're using those, you probably need to install it directly from the website to get the latest version and see the updates. The major features that have come out lately that I've noticed are first-party calendar integration and first-party GPG support. There was a calendar integration but I always found it to be a bit funny and hard to get working all of the way. I never had problems with Enigmail, however. Both features work much more solidly as an included part of Thunderbird. There are other, smaller features that have come in like having e-mail addresses in the To/CC/BCC lines be places into ovals to show them as a distinct, drag-able element. The Thunderbird codebase is old and is full of a ton of features, transforming it in a way that is true to its past and moves towards a better future is going to take time but it is coming along. Sure, some of the major features were available as plug-ins but they're much more solid now that they're built-in. |
This is very tricky.
Thunderbird keeps breaking addons compatibility (as an end user, I don't care if this is justified or not), by supporting main versions for short times (v68 was released less than two years ago).
An O/S like LTS Ubuntu, which has a 4+ years support cycles, is systematically forced to break TB compatibility during each cycle, which is contrary to the O/S versioning guidelines (which typically freeze the program versions, with the exception of security upgrades, e.g. web browsers).
As a side effect, addons, which give TB a significant value (I'd argue that they give its only value - even Google Calendar is not natively supported) slowly disappear.
Thunderbird is essentially systematically and forcefully breaking versioning and compatibility. I believe something's broken in the team/company.
