Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
A side-by-side editorial comparison of Dendrite and SlickText — release velocity, themes, recent moves, and the top alternatives to consider.
A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
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.

This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.
Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.

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.
