77 Commits • 29 Features
May 1, 2026May 2026 was a focused delivery month for mito-ds/mito, emphasizing UI polish, Mito AI enhancements, stability, and developer ergonomics to accelerate business value. Key features improved user experience and consistency, while reliability and testing were hardened to support faster, safer releases. Notable outcomes include a context-action button redesigned as an accessible icon with uniform hit areas, document-mode and notebook UX refinements, and broader Mito AI capabilities (ip widgets integration, kernel status UI, and document-mode reactive notebooks). CI stability improvements and cross-suite test fixes reduced release risk, and developer-facing changes expanded internal testing capabilities with dev-only model exposure and refreshed versioning/lockfile maintenance.
