 - `vmware-horizon-client` was renamed to `omnissa-horizon-client`, following [VMware's sale of their end-user business to Omnissa](https://www.omnissa.com/insights/introducing-omnissa-the-former-vmware-end-user-computing-business/). The binary has been renamed from `vmware-view` to `horizon-client`.
 
+- `yggdrasil-jumper` has been updated to v0.4, changing traversal protocol. See [release notes](https://github.com/one-d-wide/yggdrasil-jumper/releases/tag/v0.4.0).
+
 - `neovimUtils.makeNeovimConfig` now uses `customLuaRC` parameter instead of accepting `luaRcContent`. The old usage is deprecated but still works with a warning.
 
 - `python3Packages.pyocr` no longer supports `cuneiform` on Linux by default. It is still possible to enable it using `withCuneiformSupport` override.
