The open source tool now allows Buzz agents to execute the buzz CLI in terminal tools and features configurable threading that anchors replies to the NIP-10 thread root. This v0.21.0 update, called the Pantheon Release, incorporates more than 14 community pull requests to fix bugs and improve quality of life.

Additional updates include streaming edits and a security fix to prevent cross-profile leaks by restricting terminal credentials to an agent's subprocesses. Users can update the software by running the 'hermes update' command.
