What is Signal?

Closing the UX gap while pushing the crypto frontier.

Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.

What is Rocket.Chat?

Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

Closing the UX gap while pushing the crypto frontier.

◆ Current state

Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.

◆ Where it's heading

The cadence over the last 12 months shows a deliberate alternation between cryptographic milestones and feature catch-up. Backups, polls, pinned messages, and group labels are the kind of work Signal historically deferred; shipping them in quick succession signals a strategic decision to remove every easy reason a user might leave for WhatsApp or iMessage. Meanwhile SPQR positions the protocol for the next decade of cryptographic threat models, keeping the security story intact while the UX story finally catches up.

◆ Prediction

Secure backups will graduate from Android beta to iOS and Desktop within the next two releases. Expect another round of feature-parity work — message editing depth, richer media handling, or reactions — before the next protocol-level cryptographic move.

Rocket.Chat finishes the 8.8 calling work while the licence wall for SSO gets a date.

◆ Current state

The 8.8 candidate line is winding down. rc.2 is a bare Meteor version bump with no user-visible change, following rc.1 which promoted Voice Call Screen Sharing to stable and turned on the in-room call interface for every call, screen sharing available or not, alongside repairs to a message list that could quietly load a whole room's history in the background. The release that still defines the line is rc.0: LDAP and SAML deprecated on non-Premium workspaces with 9.0.0 named as the cutoff, forced end-to-end encryption for new private rooms, classification banners for ABAC-managed rooms, and the apps-engine default runtime moved from Deno to Node.

◆ Where it's heading

Two threads run at once and point in different directions. The calling stack keeps maturing on its own — voice, then screen sharing, now a consistent in-room surface for both — which is Rocket.Chat absorbing functions its users would otherwise reach for a separate tool to get. Against that, the 9.0 licence requirement for LDAP and SAML sorts the install base: regulated and government deployments that will pay, and unlicensed self-hosted workspaces that were there for the absence of a per-seat bill. The rc train itself has settled into a familiar shape, one substantive rc.0 followed by bumps and fixes.

◆ Prediction

Expect 8.8 to go final once the message-list fixes settle, with the LDAP and SAML licence requirement, not any calling feature, as the story of 9.0. The open question is whether the Deno-to-Node runtime switch surfaces app compatibility reports before then.
