Hermes Agent v0.21 brings bots, cron memory and browser control

Hermes Agent v0.21.0 adds built-in Bot Mode to its desktop app, giving agent profiles names and avatars, plus shared rosters and group chats for users and multiple bots.

Scheduled cron agents can now retain persistent memory, carry output between runs and use durable notepads, while subagents can be steered or stopped during execution.

The release also adds a unified MCP management page, direct control of the in-app browser, new model providers and expanded security approvals and redaction.
