Apr 1, 2026April 2026 Monthly Summary – stack-auth/stack. Focused on strengthening authentication, security controls, developer experience, and docs workflow. Implemented an authentication refactor to support anonymous user filtering, separate Users and Trusted Domains, and add server-side flags for anonymous users. Launched Fraud Protection sub-application to improve risk controls. Enhanced error messaging for debugging and user guidance, and expanded coverage for Emailable errors. Streamlined docs and developer experience by integrating Mintlify docs into the dev workflow, reorganizing the docs structure (including moving docs from /docs to /guides) and updating the welcome page and sidebar content, while reducing visual motion and improving UI/UX. Improved onboarding flow, CMD+K actions, and sign-in/sign-up experiences. Upgraded build tooling to pnpm exec, and addressed deployment and reliability issues with Vercel integration. Fixed critical sequencing/tenancies bugs to improve stability, and temporarily removed mint broken-links to reduce flaky deployments.

Feb 1, 2026February 2026 performance highlights for stack-auth/stack. The team delivered a strong mix of core product enhancements, reliability improvements, and developer-focused optimizations that collectively reduce user friction, strengthen security, and accelerate delivery. Key features delivered include CEL-based dynamic sign-up rules with a visual builder, analytics, and admin-restriction support, plus an expanded UI for managing sign-up behavior. Observability and reliability were enhanced through tracing for the email health endpoint, long-running request warnings, and improved logging for poller/sequencer, resulting in more actionable telemetry and reduced noise. Data integrity and QA processes were strengthened with broader data checks, lint/test stability fixes, and migration test coverage, improving overall quality and confidence. Security and reliability were hardened via TLS enforcement, fixes to restricted user schemas, and domain trust improvements. Performance and DevOps got a boost from proxy caching optimizations, CI/run-time improvements, and ongoing package/tooling upgrades to streamline development and deployment.

Nov 1, 2024November 2024 performance summary for stack-auth/stack: Delivered a cohesive mix of feature updates, security hardening, localization, and reliability improvements that enhance security posture, upgrade readiness, and user experience. Key outcomes include aligning core dependencies and package versions across the batch (Fern bumped to 0.44.x) to reduce tech debt and compatibility risk, adding Next.js 15 support with corresponding hydration fixes to enable a smooth upgrade path, and implementing security hardening (Default SameSite cookies) along with robust OAuth/callback handling and safeguards against duplicate auth channels. Localization and accessibility were strengthened with Quetzal translations and UI/UX improvements (autocomplete attributes, translation overrides, SDK subtitles). Reliability and observability gained momentum through delayed version alerter errors to cut false positives, Sentry stabilization, log noise reduction, and CI/CD/build system enhancements. Overall, these efforts reduced maintenance burden, improved upgrade readiness for customers, and enhanced system observability and security.
