## Overview

Hermes Agent v0.21.2 shipped a focused repair campaign for the `state.db` fragility that v0.21.0 introduced.

**Session storage is stable again.** Six PRs fixed root causes rather than symptoms, closing 44 issues: concurrent writers no longer cancel each other's locks, healthy databases stop being reported as corrupt, and one bad row no longer takes down `sessions list`.

**Remote Desktop and Cloud sessions stopped expiring mid-use.** Refresh requests carrying the same rotating token now coalesce, so a Desktop wake burst can't replay a rotated token into reuse detection and revoke the whole session. Refresh also moved off the event loop, so a slow identity provider no longer freezes the status check.

**Three rollup tags landed ahead of v0.22.0's curated notes.** v0.21.1, v0.21.4, and v0.21.5 tag main for Docker images, Hermes Cloud, and hosted deployments; the full writeup is deferred. Inside those windows:

- A Desktop plugin SDK with composer draft hooks, sidebar nav preferences, typed settings/skills/toolsets/profiles bridges, and a sandboxed embed primitive
- A Simple/Advanced interface mode for Desktop, plus a Connectors page replacing the MCP tab
- `skills.auto_load` to pin skills into every new session's prompt
- `--format stream-json` JSONL output for the CLI
- A host-wide gateway lock so Desktop attaches to the running backend instead of spawning a second one
