What is Dovecot?

Dovecot's 2.4 rewrite is still being paid for — twelve CVEs across two releases, two of them 2.4 regressions.

Dovecot 2.4 broke configuration compatibility outright in January 2025 and the line has been stabilizing ever since. The last two releases are dominated by security work: 2.4.3 shipped eight CVEs including SQL and LDAP injection when auth_username_chars is empty — both labelled v2.4 regressions — and 2.4.4 added four more, among them a fakeable CRAM channel binding and an incomplete earlier fix. Alongside that, 2.4.4 permanently drops root privileges in indexer-worker, quota-status and script-login before they serve requests.

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.

Dovecot's 2.4 rewrite is still being paid for — twelve CVEs across two releases, two of them 2.4 regressions.

◆ Current state

Dovecot 2.4 broke configuration compatibility outright in January 2025 and the line has been stabilizing ever since. The last two releases are dominated by security work: 2.4.3 shipped eight CVEs including SQL and LDAP injection when auth_username_chars is empty — both labelled v2.4 regressions — and 2.4.4 added four more, among them a fakeable CRAM channel binding and an incomplete earlier fix. Alongside that, 2.4.4 permanently drops root privileges in indexer-worker, quota-status and script-login before they serve requests.

◆ Where it's heading

The 2.4 line is a rewrite absorbing its own cost. Dependencies are being replaced rather than pinned — libicu swapped for an in-house unicode library, libpcre2 brought in for regular expressions — and the process model is being tightened, with permanent privilege drops and a reworked service_reuse_port that pre-creates one socket per process. IMAP4rev2 and UTF-8 mail remain behind build flags and config toggles, so the modern-protocol work is real but deliberately unshipped.

◆ Prediction

Expect the CVE cadence to keep tracking the areas the rewrite touched — auth escaping, IMAP parsing limits and the variable expansion introduced in 2.4 — rather than long-settled code. The experimental IMAP4rev2 and mail_utf8 flags are the obvious candidates to graduate once the security churn slows, though nothing in these entries sets a date.

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.
