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.
What is Subsplash?
Subsplash's Workflows feature goes GA with email automation on every step, unifying church operations in one platform.
Subsplash is systematically converting its Workflows feature from beta to a full operational backbone for church teams: email automations trigger on card movement, a 'My Cards' view surfaces all assigned work across every workflow, completion notifications go to team leaders automatically, and the rebuilt Transfers & Reconciliation page handles bank deposit matching with audit trails. The AI People Assistant (natural language filtering) and Trends AI (media + campaign data) are building toward a data-informed operations layer.

Rocket.Chat
6.3COMMS
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.
Subsplash
2.5COMMS
Subsplash's Workflows feature goes GA with email automation on every step, unifying church operations in one platform.
◆ Current state
Subsplash is systematically converting its Workflows feature from beta to a full operational backbone for church teams: email automations trigger on card movement, a 'My Cards' view surfaces all assigned work across every workflow, completion notifications go to team leaders automatically, and the rebuilt Transfers & Reconciliation page handles bank deposit matching with audit trails. The AI People Assistant (natural language filtering) and Trends AI (media + campaign data) are building toward a data-informed operations layer.
◆ Where it's heading
Subsplash is moving toward unifying giving, event management, people management, and operational workflows into a single platform for churches — reducing dependence on external tools like SurveyMonkey for surveys or separate streaming platforms. The 'My Cards' view and email automation completion notifications are the kinds of features that shift Workflow from a nice-to-have into a primary daily interface for church staff.
◆ Prediction
Automations will gain conditional branching and third-party integrations (email providers, SMS), and Trends AI will expand to include workflow completion and giving pattern correlations — moving toward a full church operations intelligence layer.
