What is Dovecot?

Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.

Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.

What is Apprise?

The final v1.x release slipped by one patch, but the v2 deadline stands.

Apprise is a Python notification library that fans a single call out to more than 150 services. Weighted tagging in v1.11 turned that fan-out into ordered delivery with fallback, and the releases since have been service accretion and bug clearance. v1.13.0 was announced as the last of the v1.x line; v1.13.1 has now shipped anyway, adding Signalgrid and Lauther support and fixing a memory-backed attachment failure, with the maintainer repeating the end-of-line notice and adding that he means it this time.

Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.

◆ Current state

Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.

◆ Where it's heading

Two things are being worked at once. Security is the visible half, and the volume is striking — resource-exhaustion and parser issues in IMAP THREAD, LIST and ID, a CRIME-style compression side channel, an authentication bypass through XCLIENT forwarding. The quieter half is that fixes are increasingly gated behind version declarations: the THREAD fix needs a new index format enabled only by raising dovecot_storage_version. That mechanism, introduced with 2.4.0, is now doing real work, letting operators take format changes on their own schedule.

◆ Prediction

Experimental flags for mail UTF-8 and IMAP4rev2 have carried unchanged through every 2.4 release so far; the next branch-defining move is one of those graduating to default rather than another security round.

6.3

The final v1.x release slipped by one patch, but the v2 deadline stands.

◆ Current state

Apprise is a Python notification library that fans a single call out to more than 150 services. Weighted tagging in v1.11 turned that fan-out into ordered delivery with fallback, and the releases since have been service accretion and bug clearance. v1.13.0 was announced as the last of the v1.x line; v1.13.1 has now shipped anyway, adding Signalgrid and Lauther support and fixing a memory-backed attachment failure, with the maintainer repeating the end-of-line notice and adding that he means it this time.

◆ Where it's heading

The v1 line is being closed out in patches rather than stopped cleanly, which is the normal shape of a maintainer-led project absorbing community pull requests faster than it can cut a major version. The ask to downstream projects has not changed — pin to >=1.0.0,<2.0.0 — and v1.x is stated to keep security support for a year or two after v2 lands. What v2 actually breaks is still not described in any of these entries.

◆ Prediction

The next release is likely another v1.x patch of the same shape — community service plugins plus attachment and protocol fixes — unless a v2 alpha appears first. Nothing in these entries indicates which.
