What is Notion?

Every release now lands on the agent: what triggers it, what it can reach, what it costs.

Since Notion 3.6 shipped External Agents, essentially the whole changelog has been agent infrastructure. Custom Agents gained a meeting-note trigger, calendar tools, and a one-click path to share docs into their context; Workers got usage tracking in the credits dashboard ahead of the beta ending; and the model picker now exposes scorecards for speed, intelligence and cost with a per-request effort dial. The one non-agent item in the window is high contrast mode.

What is Stalwart?

Stalwart is chasing mail RFCs and its own storage layer at the same time

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

Notion vs Stalwart: editorial side-by-side

PMCOMMS
6.3

Every release now lands on the agent: what triggers it, what it can reach, what it costs.

◆ Current state

Since Notion 3.6 shipped External Agents, essentially the whole changelog has been agent infrastructure. Custom Agents gained a meeting-note trigger, calendar tools, and a one-click path to share docs into their context; Workers got usage tracking in the credits dashboard ahead of the beta ending; and the model picker now exposes scorecards for speed, intelligence and cost with a per-request effort dial. The one non-agent item in the window is high contrast mode.

◆ Where it's heading

Notion is assembling the unglamorous half of an agent platform - triggers, permissions, connections, metering - rather than adding capabilities. The sequencing is deliberate: agents that can act on your calendar and fire off meeting notes need a permission model and a visible bill before anyone runs them on a team. Surfacing model cost and effort to the end user points the same way, pushing the spend decision down to whoever writes the prompt.

◆ Prediction

The Workers beta ending is the next dated event to watch, and pricing for it is the likeliest announcement; expect further agent triggers beyond meeting notes and more connected tool surfaces on the calendar pattern.

S5.0

Stalwart is chasing mail RFCs and its own storage layer at the same time

◆ Current state

Stalwart ships roughly weekly, and the releases divide cleanly between standards implementation and correctness work. v0.16.18 turns toward resource control — bounds on decompressed inbound DMARC and TLS report size, a cap on RocksDB block-cache memory, column families tuned per access pattern, and a queue scheduler that stops rescanning from the earliest pending event. The preceding releases added IMAP UIDONLY, UIDBATCHES and MESSAGELIMIT, plus JMAP email push and VAPID.

◆ Where it's heading

Two threads run through every release. One is RFC coverage across IMAP, JMAP, CalDAV and WebDAV, implemented close to the specification including drafts. The other is a long tail of protocol-conformance fixes, many of them cases where JMAP and IMAP disagreed about the same state. The newest release adds a third: memory and scheduling limits, which is what a server codebase starts doing when deployments get large enough for defaults to hurt.

◆ Prediction

Expect continued RFC additions across the JMAP and IMAP surfaces, with more of the storage-tuning work that v0.16.18 started as RocksDB deployments scale.
