March 2026 performance highlights: delivered substantial business value through typing and linting upgrades, improved API stability for quantizers, and stronger CI/QA tooling across transformers and doc-builder. Key features included expanded type checking for generation, new typing rules (rule 11) and expanded model-structure lint rules; typing improvements for AQLM quantizers; and model-linter enhancements with a new rule (rule 10) plus a caching layer to speed up lint passes. We centralized AI agent templates in .ai for consistency and discoverability, and rolled out CI/QA improvements such as a network debug report, anti-slop action, QA unification, and faster docstring checker performance. Major bugs fixed include signal lip import issues and Eurobert/test kwargs decorator gaps, along with AQLM quantizer signature alignment to updated APIs, reducing production risk.
