+
+Releases have happened recently that revolve around [Poezio][poezio], a TUI
+(Terminal UI) client for XMPP, including Poezio itself ([0.14][poezio014]),
+its backend XMPP library [Slixmpp][slix], and also the
+[poezio][poezio-omemo] and [slixmpp][slix-omemo] plugins for OMEMO.
+
+# Many bug fixes and improvements
+
+[Mathieui][mathieui] has already made a proper [release note for
+Slixmpp][slix180] for it and I invite you to read it! It includes many
+bugfixes of course, and internal changes around async handling, that may
+reflect on some of the APIs you are using.
+
+Poezio has also seen many improvements.
+
+Internally, for one, our default branch has also been moved to "main", many
+type hints have been added, implicit casts (safeJID) have been removed, lots
+of event handlers and calls are now async, APIs from Slixmpp are being used
+instead of redoing our own, many refactoring, various performance
+improvements.
+
+A big license change has happened, and poezio is now licensed under GPLv3+!
+While I am not exactly in favour of intellectual property[^0], this is a
+straightforward lever we have against capitalism[^1]. Poezio being a prime
+resource for Slixmpp examples, GPL code should reasonably ensure that the 4
+freedoms reach the end-users. In practice, this will in term allow for
+poezio-omemo to be merged into Poezio. I am now personally hoping for Slixmpp
+to change its license as well.
+
+[^0]: TODO: write about this. A TL;DR would certainly be "abolish intellectual
+  property, and private property in general".
+[^1]: When they don't decide to ignore it and give us the finger.
+
+And others more visible to users! To name a few, quality of life improvements
+such as `xmpp:...?join` URIs handling in `/join`, impromptu rooms creation is
+now more reliable and creates rooms with shorter names. Read more [in the
+changelog][poezio-changelog].
+
+Plugins have also seen changes. A new `untrackme` plugin now replaces the
+deprecated `remove_get_trackers`. [Link Mauve][linkmauve] has also developped
+a sticker plugin, similar in essence to what [Movim][movim] has been doing for
+ages. And again many fixes.
+
+Many of these fixes have been realized by [mathieui][mathieui], who is by far
+the biggest committer on the release, and in general probably the person with
+the best understanding of the project. Thanks also to louiz for providing the
+infrastructure all this time, and to eijebong, Ge0rG, Kaghav Gururajan,
+kaliko, Thomas Hrnciar and southerntofu for the many patches.
+
+# Encryption
+
+The Poezio `E2EEPlugin` API has been improved to accomodate changes in
+poezio-omemo, slixmpp-omemo and changes of the OMEMO backend library. Two
+plugins which are also seeing changes!
+
+Heartbeats are now supported. Heartbeats are meta-messages which transfer only
+cryptographic key material (nothing else) and are used to strengthen OMEMO's
+forward secrecy. This is particularly relevant on clients like Poezio that can
+stay running in the back for some time, receiving messages without replying.
+
+Some other changes include colored fingerprints using the [Consistent Color
+Generation][XEP-0392] document -- such as specified in the current (0.8)
+[OMEMO][XEP-0384] spec, and sending encrypted media (aesgcm URIs).
+
+What hasn't changed is that this plugin lacks a UI and trust management.
+Hopefully this should come next, with a little motivation to do UI work.
+
+# What comes next
+
+All in all, there aren't (m)any revolutionary changes, but with these releases
+come many fixes for paper cuts that hopefully make users happier.
+
+This makes me think that even though Poezio is far from being perfect, there
+doesn't seem to be many important things missing. There are however changes
+that would require a lot of refactoring, such as a multi-account feature.
+
+We have decided to start migrating Poezio to Rust, in part to be able to
+refactor the project more easily, but also because it's a language we've come
+to appreciate over the years over multiple projects, but more specifically
+with [xmpp-rs][xmpp-rs].
+
+All of this will happen right after the release, and we invite interested
+people to join the effort!
