6.3COMMS
Textellent leans into franchise SMS compliance with always-on 10DLC monitoring.
◆ Current state
One genuine product announcement anchors the feed: always-on compliance monitoring and franchise-wide 10DLC handling, plus a brand-wide Do Not Text control aimed at multi-location systems. The rest of the crawled entries are SEO articles — SMS tax rules, text abbreviations, delivery-status explainers, and a Twilio-alternatives roundup — carrying no product change.
◆ Where it's heading
Textellent is positioning around the operational pain that carrier 10DLC rules create for franchises: registration bottlenecks and ongoing compliance risk across many locations. Continuous monitoring and network-wide controls suggest a move from point SMS tooling toward compliance infrastructure for multi-location brands.
◆ Prediction
Expect further franchise-oriented compliance features — centralized registration, network-wide opt-out and reporting — deepening the multi-location wedge.

Stalwart races to implement the newest email standards across its all-in-one server
◆ Current state
Stalwart is an open-source, all-in-one mail and collaboration server (SMTP/IMAP/JMAP/CalDAV) shipping a fast 0.16.x point-release train. Recent releases are dominated by standards implementation and protocol-conformance work, layered over steady security hardening and a long tail of targeted bug fixes.
◆ Where it's heading
The product is doubling down on being the most standards-complete self-hosted mail server: early DKIM2 and DMARCbis authentication, IDN support, encryption-at-rest for S/MIME, and a sustained push to pass the JMAP test suite. Security hardening runs alongside — DANE downgrade-attack defenses, auto-ban fixes, binary attestation on every build.
◆ Prediction
Expect continued rapid 0.16.x releases advancing draft email-authentication standards and JMAP conformance; a larger 0.17 or 1.0 milestone becomes likely once the JMAP suite fully passes and the DKIM2/DMARCbis drafts stabilize.
