Quoting: Mozilla Thunderbird 146 Brings OpenPGP Keyserver Settings —

Mozilla has released Thunderbird version 146 of its widely adopted free and open-source desktop email client, now available for download.

On the new features side, the update introduces UI-based configuration of a preferred OpenPGP keyserver, giving users clearer control over where their public keys are fetched and published. Alongside this, Thunderbird migrates all existing logins to modern AES-based cryptography, improving security without requiring user action.

The release also resolves a broad set of issues across core mail workflows. Crashes related to server subscription logic and folder renaming have been fixed, and memory cleanup has been improved when opening new windows from the folder pane.

Changes this month may sound less flashy compared to last month, which saw Thunderbird 145 add Microsoft Exchange support (albeit with some caveats, carveouts and a couple of capabilities still be added).

Plus, work on readying Thunderbird Pro, the paid-for subscription-based webmail, appointment and file sending service excepted to cost upwards of $9/m, for a soft-launch continues. Those services are about to enter community testing.
