hermes-agent v2026.6.5 release notes: what's new & changelog

Hermes Agent v2026.6.5 delivers a native desktop application, a full-featured web administration panel, and significant enhancements to remote gateway connectivity and multi-profile management.

Key Changes

Native Desktop Application

A new native desktop app (built with Electron) is now available for macOS, Linux, and Windows. This application moves Hermes beyond the terminal, providing a polished GUI that includes:

• Full Chat Experience: Streaming responses, a searchable session list with archiving capabilities, and a Cmd+K command palette.
• Enhanced File Handling: Users can now drag and drop files anywhere in the chat area or paste images directly from the clipboard.
• L10n Support: The desktop app includes a full Simplified Chinese (简体中文) translation across all UI surfaces.
• Lifecycle Management: Features include one-click installation and in-app self-updates.

Web Administration Panel

The web dashboard has evolved into a complete administration surface, removing the need for SSH access to edit config.yaml for many tasks. New capabilities include:

• MCP Management: A full MCP catalog with enable/disable toggles and one-click installation.
• Channel Configuration: A dedicated Channels page to set up and test every gateway messaging platform (Telegram, Discord, Slack, etc.) from the browser.
• System Operations: A System page for gateway controls (start/stop/restart), memory provider selection, and a "Debug Share" button for uploading redacted reports and logs.
• Auth Flexibility: Support for pluggable username/password login and generic self-hosted OIDC providers (e.g., Keycloak, Authentik).

Remote Gateway & Multi-Profile Support

Connectivity between the desktop app and remote backends has been significantly hardened:

• Remote Auth: Support for OAuth-gated and username/password-protected remote gateways, including transparent session rotation via refresh tokens.
• Per-Profile Remotes: Users can now configure specific remote hosts for individual profiles, allowing a single desktop instance to connect to multiple different backends.
• Global Remote Mode: A single remote dashboard can now serve multiple profiles, with full support for listing, resuming, and creating new chats that honor the specific profile's identity and database.

Core Agent & Tooling Improvements

• Fuzzy Model Picker: A new fuzzy-searchable model picker is available across the desktop app, web dashboard, TUI, and CLI.
• Undo Functionality: The /undo [N] command allows users to take back the last N turns across the CLI, TUI, and messaging platforms.
• Leaner Skill Set: The default bundled skill set has been trimmed to remove redundant tools (e.g., spotify, linear), while NVIDIA/skills has been added as a trusted Skills Hub tap.
• New Models: Added support for deepseek-v4-flash, MiniMax-M3 (with 1M context), and qwen3.7-plus.

Impact

User Accessibility

The introduction of the desktop app and "Quick Setup via Nous Portal" significantly lowers the barrier to entry, allowing new users to go from installation to their first message in seconds without requiring deep CLI knowledge.

Operational Efficiency

Administrators can now manage the entire agent lifecycle—from MCP server pairing and webhook creation to security audits and backups—directly through the browser, reducing the reliance on manual configuration file edits.

Security & Reliability

This release addresses critical security vulnerabilities, including CVE-2026-48710 (Starlette BadHost) by pinning Starlette ≥1.0.1. It also introduces SSRF off-loop hardening and subprocess credential stripping to protect sensitive API keys.
