v2026.3.28 — The Hardening Release
Released: March 28, 2026 Theme: Hardening and stabilization Breaking Changes: None
Core Highlights
1. Hugging Face as a First-Class Provider
Hugging Face Inference Endpoints are now a native inference provider.
Meaning: call any of the 100,000+ open-source models on HF directly — no inference server to build yourself.
2. Telegram Private Chat Topics
Supports Topics in Telegram Private Chats — parallel threads within a single conversation.
Good for: project management, multi-task tracking.
3. Native Modal SDK Replaces swe-rex
Hermes used swe-rex as a code-execution sandbox. This release switches to Modal’s official SDK — better stability and performance.
4. Plugin Lifecycle Hooks
Plugin lifecycle hooks (before-prompt, after-response, etc.) land in the agent execution loop — much richer extension surface.
5. Nix Flake Support
Developers can nix develop into a one-command environment.
Upgrade Recommendations
- Modal SDK (code execution) users: upgrade — noticeably more stable
- Open-source model users: try the HF integration after upgrading
- Everyone else: safe to upgrade
