 # Changelog
 
+## 0.3.0 - unreleased
+
+- README: a summary of what the collection contains, a "What you can build"
+  table, the functions grouped by role with hardware needs and licenses, and
+  release badges instead of version numbers that went stale.
+- Added mxl-avsync (now released) and more complementary projects (MXL
+  docs and awesome-mxl, EASY MXL, mxl-k8s, BCP-007-03).
+- States that this is an independent community project.
+- The Compose examples are unchanged (same pinned images as 0.2.0).
+
 ## 0.2.0 - 2026-10-24
 
 - FlowXer vision mixer (19.26.68) as a media function: README table,

+Media Facility (DMF).** Gateways (SMPTE ST 2110, SRT, SDI), a vision mixer,

+This repository is the entry point. It holds no media code: it lists the

+examples and Kubernetes notes to run them together.
 
 Each function repository stays the source of truth: its README and
 SPECIFICATION document every setting, port, metric and API. If this page and a
 function's README disagree, the README wins.
 
+This is an independent community project. It is not part of, or endorsed by,

+Images are on GitHub Container Registry (`ghcr.io/leeo86/<repo>`). Release
+tags are `X.Y.Z`, `X.Y` and `X`; most repos have no `latest`, so pin a version.
+The badges show each repository's latest release. The Compose examples pin a
+set that was run together; see [CHANGELOG.md](CHANGELOG.md).
+
+**Status.** All functions below have tagged releases, a container image and a
+changelog, are tested on real hardware, and several run continuously on a
+multi-host Kubernetes test platform. They are proofs of concept for MXL-based
+production, not certified products. Features a README marks as planned are not
+in the image yet.

 ## Getting started
 
 1. Prepare the host: [docs/requirements.md](docs/requirements.md)
    (tmpfs MXL root, TAI time, inotify limit, optional GPU).
 2. Run the single-host example: [compose/single-host](compose/single-host/).
+   It needs no special hardware: a Linux x86-64 host with Docker is enough
+   for the test player, multiviewer, scopes, audio mixer, replay, browser
+   source and WebRTC monitor.
 3. Two hosts over RDMA: [compose/multi-host-rdma](compose/multi-host-rdma/).
 4. Kubernetes notes: [docs/kubernetes.md](docs/kubernetes.md).
