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 Proton Bridge?

Proton Bridge spends its first release in ten weeks on crashes, memory bounds and dead code

v3.26.0 is a maintenance cut. The user-visible items are a macOS 27 crash fix, bounded CPU and memory in the Gluon RFC parser, deletion of orphaned unencrypted vaults once keychain access returns, and a meta+W shortcut. The rest is internal: two unused subsystems removed from go-proton-api, two Go toolchain bumps, gomock swapped for uber-go/mock, and June and July vulnerability patches folded in.

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.

P2.5

Proton Bridge spends its first release in ten weeks on crashes, memory bounds and dead code

◆ Current state

v3.26.0 is a maintenance cut. The user-visible items are a macOS 27 crash fix, bounded CPU and memory in the Gluon RFC parser, deletion of orphaned unencrypted vaults once keychain access returns, and a meta+W shortcut. The rest is internal: two unused subsystems removed from go-proton-api, two Go toolchain bumps, gomock swapped for uber-go/mock, and June and July vulnerability patches folded in.

◆ Where it's heading

Releases arrive in long gaps — ten weeks since v3.25.0 — and each one bundles a quarter of dependency hygiene with a handful of IMAP correctness fixes. The recurring theme is RFC 3501 conformance and resource bounds in the mail parser rather than new capability, which is what a local IMAP shim for an encrypted mailbox is supposed to look like.

◆ Prediction

Given the pattern of shipping OS-compatibility fixes shortly after a macOS release, the next cut is likely another maintenance bundle timed to whatever the current macOS version breaks.
