Mar 1, 2026

March 2026 (2026-03) – convex-backend focused on stabilizing deployments, tightening developer experience, and modernizing testing/docs to improve automation and reliability. Key platform/API work delivered via backend changes to deployment lookups and creation semantics; UX improvements in deployment display and expiry warnings; targeted bug fixes to improve error clarity and build reliability; and targeted tooling updates to keep dependencies and codegen current. This combination reduced operational risk, improved automation, and accelerated feature delivery for customers relying on Convex deployments. Highlights include platform APIs to fetch deployments by reference with new default deployment lookups, deployment creation is_default flag and improved non-default deployment display, and warnings around deployment expiry to prevent unnoticed degradations. Docs and tests were updated to reflect Vitest v4 changes and to validate multi-environment guidance, ensuring smoother onboarding and fewer support queries. Several stability fixes and code-quality improvements were completed (refactoring ExecutionId/RequestId, codegen regeneration, and dependency patching) to improve maintainability and reliability across the codebase. Technologies and skills demonstrated include Rust error-message formatting for clearer user feedback, TypeScript/React-based UI and Storybook enhancements, Vitest testing, CI reliability improvements, and tooling/workflow upgrades (ESLint plugin release, dependency updates).

Feb 1, 2026

February 2026 focused on delivering deployment flexibility, improved developer experience, and platform API stability across convex-backend and convex-helpers. Key features include dashboard codegen regeneration reflecting latest changes, refactoring the Region component for easier maintenance, and enhancements to deployment and region defaults and provisioning (default region can be null, default region added to team settings, and propagation in provisioning with support for custom regions). Platform APIs gained the ability to create non-default deployments and modify deployment settings (with a rollback later to preserve stability). Dashboard modernization includes a migration to Recharts v3, the ability to create development deployments from the dashboard, and improved env vars visibility and typing. Node.js 24 support was added to Node actions with related documentation. These efforts delivered measurable business value by reducing onboarding friction, enabling more flexible environments, and improving developer productivity and UX.
