What is Chat Data?

Chat Data is turning its chatbot platform into a workflow runtime with payments built in.

Chat Data is no longer just a custom-chatbot builder — recent shipments push it toward an end-to-end agent platform. The last two weeks added cron-driven workflow triggers, native Stripe OAuth, deeper page-context tiers, and access to GPT-5.5. Each move targets a different gap that previously forced customers to bolt on outside tooling.

What is mailcow?

mailcow's release notes are almost entirely upstream security currency.

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

Chat Data vs mailcow: editorial side-by-side

C5.4

Chat Data is turning its chatbot platform into a workflow runtime with payments built in.

◆ Current state

Chat Data is no longer just a custom-chatbot builder — recent shipments push it toward an end-to-end agent platform. The last two weeks added cron-driven workflow triggers, native Stripe OAuth, deeper page-context tiers, and access to GPT-5.5. Each move targets a different gap that previously forced customers to bolt on outside tooling.

◆ Where it's heading

The arc is unmistakable: chatbot to agent to autonomous workflow with monetization wired in. Scheduling decouples Chat Data's automations from live user prompts; direct Stripe handles the revenue side; richer page context closes the gap with retrieval-heavy competitors. Pricing is shifting in lockstep, with a per-node credit charge for non-AI workflow steps replacing the prior all-or-nothing model.

◆ Prediction

Expect the next releases to focus on workflow observability — run history, retries, conditional branches — and likely an agent marketplace or template gallery to drive adoption of the scheduled-trigger surface.

5.0

mailcow's release notes are almost entirely upstream security currency.

◆ Current state

mailcow ships named seasonal releases with lettered revisions, and nearly every revision exists to pull in an upstream security fix - Redis, ClamAV, SOGo, Rspamd, nginx, unbound, Postfix. Revision B of the Mooly 2026 release updates Redis 7.4.10, ClamAV 1.4.6, and SOGo 5.12.10, adds minor web UI and nginx hardening, and removes a legacy DeltaChat sieve rule. The last release with genuinely new features was the March cut, which added forced 2FA, ACME DNS-01 challenges, and a passwordless autodiscover endpoint.

◆ Where it's heading

For a self-hosted mail stack that bundles a dozen upstream components, keeping current with their CVEs is the product, and mailcow has organized its release cadence around exactly that. The pattern is consistent: a named release with some feature content every few months, then lettered revisions that are pure security currency plus small web UI escaping and validation fixes. The web interface is where mailcow's own code gets hardened - HTML escaping in quarantine views and sieve editors recurs across several revisions.

◆ Prediction

Expect the next entry to be another lettered revision carrying upstream updates, with the next named release likely bundling whatever feature work has accumulated since March.
