Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Canary Mail and SlickText — release velocity, themes, recent moves, and the top alternatives to consider.
Canary Mail spends October on fixes after its AI translation push.
Canary Mail is a privacy-focused email client on macOS, iOS, Android and Windows. Its September releases added AI features, chat history in 5.23.0 and incoming-mail translation in 5.25.0. The October 5.27.0 releases for iOS and macOS are fix-only (reply-to-sent addressing, keyboard shortcuts, sending over mobile data), and Windows 5.1.58 is another crash-fix build.
SlickText's feed is all SMS buying guides; no product release has surfaced since RCS.
SlickText's recent feed is entirely search content: SMS segmentation, church and nonprofit texting comparisons, Black Friday tactics, cost breakdowns and guides on annual plans. No release appears in the entries since the basic RCS addition.

The October 5.27.0 releases for iOS and macOS are fix-only (reply-to-sent addressing, keyboard shortcuts, sending over mobile data), and Windows 5.1.58 is another crash-fix build.
The AI layer grew in steps (chat, then history, then translation), and the latest cycle is consolidation across platforms. The shared reply-to-sent fix on iOS and macOS shows the Apple clients moving in lockstep, while Windows and Android still mostly receive stability builds.
The entries don't show what the next feature is. Composition-side AI would be the natural follow-on to translation, but the current cycle is fix-only, so a stabilization stretch is the safer read.

The content is getting more explicit about buying decisions. Vertical comparison pages, published prices and an outgrown-your-platform pitch all aim at people ready to switch. Product motion cannot be read from these posts.
Expect Black Friday content through November and more vertical comparison pages. These entries give no evidence of how RCS is progressing.
