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.
