February 2026 monthly summary for modrinth/code. Delivered reliability and UX improvements across core paths: multipart file uploads, session management, and payout notifications. Key items include a feature-focused enhancement to file upload handling, and two critical bug fixes that stabilize session behavior and payout delivery. This work reduces user friction, improves data integrity, and lowers operational risk in production processes. Key achievements: - Enhanced File Upload Handling for Multi-Part Uploads (feature): robust detection of the primary file during multi-part uploads, reduces redundant processing, and improves the user experience in the version management modal. Commit: d9d7750781a257f4bf018407decdd12fa71d5485 - Session Refresh Stability and Defaults (bug): fixes to session refresh, introduces code-defined defaults for expires and session_expires, and updates database migrations to drop existing defaults. Commit: 017f6a5afb37820f69b386624ef129d3038a850b - Payout Notification Delivery Reliability (bug): fixes FK violations in notifications_deliveries, adds tests to prevent regressions, and includes a migration to prevent stale notifications from being dequeued. Commit: 6fba33d4437bbc1e85db758fa2e321c7621f9895 Overall impact and accomplishments: - Increased reliability of core flows (uploads, sessions, payouts), reduced risk of data inconsistencies, and smoother user experiences in critical paths. - Expanded test coverage and migrations to guard against regressions in payments and file-upload logic. Technologies/skills demonstrated: - Go backend development with sqlx, SQL migrations, and regression testing - Data integrity and migration planning - Cross-team collaboration and accurate commit traceability

For 2025-04, PrismLauncher delivered key enhancements to improve mod support and launcher reliability. The changes prioritize enabling mods to access launch context by exposing main class name and game arguments through system properties, and strengthening argument parsing by adopting a robust unit-separator delimiter to prevent misinterpretation of spaces. Accompanying inline comments improve maintainability and future contributor onboarding. The work reduces mod-related launch failures, improves ecosystem compatibility, and demonstrates solid code quality and maintainability.
