What changed
Nous Research released Hermes Agent 0.23.0 with a browser-served Desktop workspace and one gateway that owns sessions across CLI, TUI, Desktop, editors, bots and cron. The release also adds multi-machine connections, group-chat routing, conversation rewind, plugin updates, MCP tool prices and spend limits.
Why it matters
A single session owner can make persistent work easier to inspect and resume across clients, but it also concentrates credentials, memory, plugin updates and remote control in one long-lived gateway.
What to do
Upgrade a disposable gateway, open one session from two clients, interrupt and rewind it, cap a paid MCP tool, rotate a plugin, disconnect one machine and verify session ownership, duplicate prevention, logs and external state before migrating persistent data.
Caveat
The immutable release establishes the artifact and feature list, not isolation or migration correctness. The release is unusually large, bundles earlier patch work and reports contributor and change counts that should not be treated as security or quality metrics.
