Hermes Agent v0.20.6 Rolls Up ~525 PRs Including Lean-Tail Compression by Default and a 50+ Server Remote MCP Catalog
NousResearch tagged Hermes Agent v0.20.6 on 2026-08-27, a patch release folding roughly 1,313 commits across ~1,557 files (+177,113/-21,682) since v0.20.5 on August 21. Notable items for agent operators: lean-tail compression becomes the default context strategy, TTL result caching lands for web_search and web_extract, tool_search goes multi-query with stemming, and the remote MCP catalog expands past 50 live-verified vendor-hosted servers including Cloudflare, Grafana Cloud, Better Stack and Railway. It also adds opt-in OS-keychain encryption for stored secrets (removing per-launch macOS Keychain prompts), consent-gated real-profile browsing, and GLM-5.3-Flash and MiniMax M3 in the model pickers.
