 # Rerun changelog
 
 
-## [Unreleased](https://github.com/rerun-io/rerun/compare/latest...HEAD)
+## [Unreleased](https://github.com/rerun-io/rerun/compare/latest...HEAD) - Dataframe & Video
+
+TODO(emilk): insert a screenshot and/or code sample here
+
+📖 Release blogpost: TODO(emilk): add link
+
+🧳 Migration guide: No breaking changes in this release!
+
+### ✨ Overview & highlights
+This release introduces two powerful features: a dataframe API (and view), as well as video support.
+
+#### ☰ Dataframe Python API
+We now have a Python API for querying the contents of an .rrd file. This integrates with popular packages such as [Pandas](https://pandas.pydata.org), [Polars](https://pola.rs), and [DuckDB](https://duckdb.org).
+
+You can read more in [the Dataframe API how-to guide](https://rerun.io/docs/content/howto/dataframe-api?speculative-link).
+
+We have also added a matching dataframe view inside the Rerun Viewer.
+Read more [here](https://rerun.io/docs/content/reference/types/views/dataframe_view?speculative-link).
+
+#### 🎬 Video
+Rerun now supports logging MP4 videos using the new [`AssetVideo`](https://rerun.io/docs/reference/types/archetypes/asset_video?speculative-link) archetype.
+This can greatly reduce bandwidth and storage requirements.
+
+While the web viewer supports a variety of codecs, the native viewer supports only the AV1 codec for the moment, but we plan to support H.264 in the near future as well.
+Read more about our video supports (and its limits) [in our video docs](https://rerun.io/docs/reference/video).
