+#### Expose MFS as a FUSE mount point
+
+The MFS root is now available as a read/write FUSE mount point at `/mfs`. This filesystem is mounted in the same way as `/ipfs` and `/ipns` when running `ipfs mount` or `ipfs daemon --mount`.
+
 #### 📦️ Important dependency updates
 
 - update `ipfs-webui` to [v4.7.0](https://github.com/ipfs/ipfs-webui/releases/tag/v4.7.0)
