What is Circle?

Circle moves from building the community to selling inside it, with upsells and attribution.

Circle's September and October releases shift weight from AI building to revenue and live engagement. October adds post-checkout upsells that charge only the difference, GA4 and Meta conversion tracking on paywalls, and an attribution tab showing the revenue behind every checkout link. September added breakout rooms for up to 10 groups, six more reaction types and custom gamification points. Paywalls, subscriptions and coupons also reached the Admin API and Circle MCP.

What is Mattermost?

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

Circle moves from building the community to selling inside it, with upsells and attribution.

◆ Current state

Circle's September and October releases shift weight from AI building to revenue and live engagement. October adds post-checkout upsells that charge only the difference, GA4 and Meta conversion tracking on paywalls, and an attribution tab showing the revenue behind every checkout link. September added breakout rooms for up to 10 groups, six more reaction types and custom gamification points. Paywalls, subscriptions and coupons also reached the Admin API and Circle MCP.

◆ Where it's heading

June to August built the operating layer around Circle AI and the page builder; the two releases since instrument the money. Attribution and upsells answer what a page or checkout link actually earned, which completes the funnel the page builder opened. Taking Paywalls into Circle MCP keeps the agent path level with the human one.

◆ Prediction

Member reviews are announced for early November, with automatic prompts, rating trends and display on Discover and websites, so the next release is largely known. Further Paywalls coverage in Circle MCP is the likeliest follow-on.

M6.3

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

◆ Current state

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

◆ Where it's heading

Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.

◆ Prediction

Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
