 - Increased default RTT Timeout (retry waiting for RTT Control Block initialization) to 1000ms in `probe-rs-debugger`. (#847)
 - Improved when RTT is initialized/retried, and removed `rtt_timeout` from recognized options of `probe-rs-debugger`. (#850)
 - Refactor `probe-rs-debugger` code as per `launch` vs. `attach` changes documented in [VS Code extension PR # 12](https://github.com/probe-rs/vscode/pull/12) (#854)
+- Breaking change: `probe-rs-debugger` and the associated [VSCode extension PR #21](https://github.com/probe-rs/vscode/pull/21) now uses camelCase for all `launch.json` properties (#885)
 
 ### Fixed
 - Detect proper USB HID interface to use for CMSIS-DAP v1 probes. Without this, CMSIS-DAP probes with multiple HID interfaces, e.g. MCUlink, were not working properly on MacOS (#722).
