While this has existed behind a pref in a beta state in 91, it will finally be usable out-of-the-box in this release. Support for the popular chat protocol: Matrix, is coming to 102. While it is also supported in Thunderbird 91, users had to enable it via a preference. Thunderbird 102 supports the Matrix protocol by default. When setting up an email, autodiscovery of calendars and address books works really well! But managing accounts and setting up after the first time has lagged. In past releases, we have improved first time account setup. The new Account Setup Hub of Thunderbird 102 changes that by providing users with a similar experience and functionality. The first time account setup process works well already, but setting up secondary accounts did not provide the same experience. When a link is added in the composer, you will have the option to convert it into a rich link preview with content displayed from the website (Twitter link pictured below, WIP). The new Thunderbird will have a feature that Twitter users are familiar with. As an example, the pasting of a Twitter link will display the message, date and time and media, if provided.

Link Preview Cards is a simple new feature that turns pasted links into previews in the compose window.

but new features enable you to better understand who you communicate with. Not only is there a design that makes it easier to navigate and interact with your contacts. After a couple of release teasing a new address book - it's coming in this release.
