# MeshCore Observer - Changelog

Changes to the MQTT observer / bridge work that powers the firmware offered on
[observer.gessaman.com](https://observer.gessaman.com/). Newest changes are at the top.

**Legend:** **New** = new capability * **Fix** = bug fix * **Improvement** = enhancement to
existing behavior * **Internal** = refactor / under-the-hood * **Docs** = documentation *
**Build** / **CI** = build system & automation. **[UP] Upstream sync** marks a merge of the
upstream MeshCore `dev` branch, which generally pulls in a new MeshCore software version.
