Hey all,
|
||
|
||
We’ve just pushed out [Matrix 1.9](https://spec.matrix.org/v1.9/)! Our last release was [Matrix 1.8](https://matrix.org/blog/2023/08/23/matrix-v1.8-release/) and brought us a whole new room version. Matrix 1.9 continues a theme of an [annual maintenance release](https://matrix.org/blog/2022/11/17/matrix-v-1-5-release/), bringing with it mostly clarifications and bug fixes.
|
||
|
||
Today’s release sees just 1 MSC formally merged to the specification, though this is expected for a maintenance release. For the last 2 months (and beyond), we have largely been focused on changes which haven’t settled enough to be MSCs yet, such as interactions with the More Instant Messaging Interoperability (MIMI) working group at the IETF.
|
||
|
||
This post covers a lot of what we’ve been up to for the last few months, and what we expect to get done for the Matrix 1.10 release cycle. As always, the full changelog for Matrix 1.9 is at the bottom of the post :)
|
||
|
||
|
||
## Messaging interoperability
|
||
|
||
One of the major features of Matrix is its ability to connect multitudes of messaging providers with a common communications fabric - a feature that is extremely useful in light of the EU’s Digital Markets Act (DMA) which requires gatekeepers to interoperate with other messaging providers.
|
||
|
||
We’ve been working with the MIMI working group at the IETF to establish a federation protocol for DMA-style messaging alongside our own experiments like [MSC3995: Linearized Matrix](https://github.com/matrix-org/matrix-spec-proposals/pull/3995). The proposed protocol for MIMI is based upon the Linearized Matrix work, but is primarily designed for an MLS-centric environment.
|
||
|
||
Discussions and experiments will continue over the next several months, and you can read all about our progress so far in [TWIM 2023-11-10](https://matrix.org/blog/2023/11/10/this-week-in-matrix-2023-11-10/#dept-of-spec-scroll).

## Custom emoji/stickers
|
||
|
||
We mentioned in Matrix 1.8’s release that we’d be taking a look at [MSC2545](https://github.com/matrix-org/matrix-spec-proposals/pull/2545), [MSC1951](https://github.com/matrix-org/matrix-spec-proposals/pull/1951), [MSC4027](https://github.com/matrix-org/matrix-spec-proposals/pull/4027), and [MSC3892](https://github.com/matrix-org/matrix-spec-proposals/pull/3892) - a family of MSCs collectively called “custom emoji/stickers”. Our review started relatively late in the Matrix 1.9 release cycle (sorry), and we started thinking about interactions with [MSC3916](https://github.com/matrix-org/matrix-spec-proposals/pull/3916)/[MSC3911](https://github.com/matrix-org/matrix-spec-proposals/pull/3911) where media is linked to a specific event.
|
||
|
||
We haven’t had a chance to really dig into the specific possible concerns on these two features overlapping, but do welcome feedback and suggestions for what might impact custom emoji/stickers over on our [dedicated tracking issue](https://github.com/matrix-org/matrix-spec/issues/1679). We’ll continue working through the problem space in the Matrix 1.10 release cycle, and hope to get both linked media and custom emoji/stickers up for FCP.
|
||
|
||
|
||
## Upcoming in Matrix 1.10
|
||
|
||
With each release we aim to have a plan for what the next release will look like, giving us a direction or theme to follow. Noting that the next release cycle has a lot of holidays (and FOSDEM) in it, we’ve got an initial list of things to look at, grouped by theme:

||
* [MSC3939](https://github.com/matrix-org/matrix-spec-proposals/pull/3939) - Account locking
|
||
|
||
This list is **not** final and will be iterated upon over the next couple of weeks. If you’ve got an MSC to add or remove, let us know in the [SCT Office](https://matrix.to/#/#sct-office:matrix.org) on Matrix. For all of the MSCs above, we aim to get them to a FCP-accepted state at a minimum, and merged to the spec if time permits (and makes sense - looking at you, Extensible Events).
