Foxglove 2.24.0

🚢 Performant API for visualizing data across a time range​

The subscribeMessageRange extension API is now generally available. Using this API, Foxglove can load data in small chunks and cache only a subset of serialized data. By doing this, heap memory usage is reduced while still allowing fast re-reads. As a result, panels can display larger datasets without exhausting memory resources.

The subscribeMessageRange API should be used instead of preload: true and context.watch("allFrames") in order to load data across a data source. These previous APIs are now deprecated.

The reference documentation for the extension API is also now available in the core Foxglove documentation. extension api docs
