 ### Changed
 
+- Adds `--uuid` flag to `hc hash`, allowing a UUID to be specified which will alter the hash [PR#2161](https://github.com/holochain/holochain-rust/pull/2161)
+- Adds `--files` flag to `hc sim2h-client`, which when set prints JSON blobs to multiple files named by space hash (the previous default behavior), and when unset prints a single JSON blob to stdout for easy parsing by script [PR#2161](https://github.com/holochain/holochain-rust/pull/2161)
