Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Session and Tuta — release velocity, themes, recent moves, and the top alternatives to consider.
Session ships new app versions and node upgrades while Pro stays on hold.
Session's 2026 started with a funding scare, then community support restored its runway in June. Session Pro reached a beta in app stores in September before its launch was paused in October during talks with an allied privacy ecosystem. Since then the work is infrastructure: lighter Session Node software, an update on Protocol v2, and on November 9 new iOS, Android and Desktop releases with further voluntary node upgrades and progress on a unified client.
Tuta's One-Click Migration can now pull mail through Google and Microsoft APIs, not just IMAP.
Tuta is an encrypted email, calendar and drive suite that ships one numbered build across web, desktop, Android and iOS. The 368.261109 build adds the option to open attachments while composing and lets One-Click Migration import from Gmail and Microsoft accounts through their APIs as well as IMAP. The rest of the batch is bug fixes: list selection flashing, spam rules not updating, alias deactivation for shared mailboxes and connection errors during migration.

With Pro paused, Session is spending its effort on the network and the client codebase: lighter nodes, Protocol v2 with forward secrecy and post-quantum encryption, and one client for all platforms. Monetization waits on the outside talks.
Expect a Protocol v2 alpha or the unified client to be the next visible release; Pro's timing depends on talks the entries do not detail.

The rest of the batch is bug fixes: list selection flashing, spam rules not updating, alias deactivation for shared mailboxes and connection errors during migration.
The visible product work is aimed at switching: the migration tool keeps gaining source options and its error handling is getting attention, including the Proton Mail Bridge path. Releases fan out to every platform within hours, so most entries are the same fix list repeated per client.
Expect more migration fixes and sources in the next builds, plus follow-up patches like the November 10 mailto fix on the web app.
