What is Synapse?
The reference Matrix homeserver shipping protocol work on a tight release train
Synapse is moving through the 1.156–1.158 line at roughly weekly cadence, with release candidates preceding each stable. The functional work is protocol-level: MSC4140 cancellable delayed events with per-user scheduling limits, MSC4354 sticky events exposed over MSC4186 simplified sliding sync, and stabilized ephemeral event sending. Version 1.157.0rc1 removed the deprecated MSC3861 auth delegation, and 1.157.2 was an out-of-band security release addressing several vulnerabilities rated up to high severity.
What is Chatwoot?
Chatwoot added voice, then pointed its AI agent at the tickets it already resolved.
Chatwoot is an open-source customer engagement platform releasing every few weeks, and the window splits between two threads. One is channel coverage, where voice calls landed in June after years as the most-requested gap. The other is Captain, the built-in AI agent, which has been getting steadily less manual — document refresh in June, and in July the ability to mine resolved conversations for suggested FAQs.

◆ Current state
Synapse is moving through the 1.156–1.158 line at roughly weekly cadence, with release candidates preceding each stable. The functional work is protocol-level: MSC4140 cancellable delayed events with per-user scheduling limits, MSC4354 sticky events exposed over MSC4186 simplified sliding sync, and stabilized ephemeral event sending. Version 1.157.0rc1 removed the deprecated MSC3861 auth delegation, and 1.157.2 was an out-of-band security release addressing several vulnerabilities rated up to high severity.
◆ Where it's heading
Development tracks the Matrix spec process directly — features arrive as MSCs graduate, and deprecated experimental paths are removed once replacements stabilize. Sliding sync is the load-bearing effort, with sticky events and ephemeral sending both being routed through it. The security release and the config regression that followed 1.157.0 show the cost of that cadence: fast lines need fast patches.
◆ Prediction
Expect the 1.158 line to continue folding MSCs into sliding sync, and further removal of experimental_features flags whose MSCs have stabilized, following the MSC3861 precedent.

Chatwoot added voice, then pointed its AI agent at the tickets it already resolved.
◆ Current state
Chatwoot is an open-source customer engagement platform releasing every few weeks, and the window splits between two threads. One is channel coverage, where voice calls landed in June after years as the most-requested gap. The other is Captain, the built-in AI agent, which has been getting steadily less manual — document refresh in June, and in July the ability to mine resolved conversations for suggested FAQs.
◆ Where it's heading
The company's own framing for voice is the tell: text channels first, voice only once the foundation was solid. With the channel set now complete, the remaining investment is in making Captain self-maintaining — its knowledge base updates itself and proposes its own content from support history rather than waiting to be fed. The help center work and the mobile AI Assist follow the same logic, putting existing capability everywhere the agent already is.
◆ Prediction
Expect the next release to extend Captain's use of resolved conversations, since both June and July releases moved in that direction. Voice is the more open question — a newly launched channel usually draws follow-up work, but nothing in these entries says what.
