Headroom— tool, 2026-09-08 Open-source context-compression proxy for AI agents (Rust core; Python/TypeScript SDKs): sits between your agent and the LLM and compresses tool outputs, logs, JSON, code and RAG chunks with format-specific, reversible compressors before the model sees them — no changes to agent code.

Maintainer relicenses from MIT/LGPL to EUPL to close the SaaS loophole— news, 2026-09-06 Henri Bergius (NoFlo, Midgard) relicensed his projects from MIT/LGPL to the EUPL-1.2 — an OSI-approved, EU-backed copyleft whose obligations extend to software offered over a network, closing the "SaaS loophole". Relevant when selecting self-hostable tools: license class is a deliberate maker choice, and network-copyleft (EUPL/AGPL) affects hosted redistribution, not internal self-hosting.
