February 2026 (chatboxai/chatbox) delivered key platform improvements across tooling, config, UI, and reliability. Migrated from npm to pnpm with new dependency scripts and compatibility adjustments for native modules, complemented by repository hygiene cleanup (removing tracked workflow files and updating .gitignore for Pro-version docs). Strengthened version management and remote configuration with current_version support and a more robust useVersion flow, addressing API handling and race conditions. Overhauled attachments UI with a grid layout, file type/size formatting, and increased upload limit to 20 to improve user experience. Enhanced context management with automatic compression and improved settings accessibility, alongside upgrading the AI SDK to enhance reliability and capabilities (1.19.0). Improved OCR error handling and monitoring with wrapped setup errors and refined Sentry reporting to enable faster remediation. These efforts collectively boost developer velocity, system reliability, user experience, and observability.
