May 2025 delivered notable improvements in stability, release readiness, and platform modernization for cosmos-sdk. Key features were organized Baseapp ABCI methods and deprecation of invariants in Baseapp, enabling cleaner evolution of the API and safer long-term refactors. We fixed critical stability issues including preventing panics when registering the same error to the global registry, addressing a race condition in baseapp states, and resolving an IterateRaw bug in collections tests. Release readiness was advanced across multiple fronts: API Beta Release Prep, Core Alpha Release Prep, X/Tx Release Prep, and server cleanup with final SDK alpha tagging, setting the stage for upcoming beta and alpha cycles. In addition, collections groundwork and alpha store integration were prepared, with timely dependency updates (collections 1.3.0, cosmos-db, depinject, IAVL bumps) and targeted proto/generation alignment. Finally, CI, testing, and code-quality improvements (tidy deps, improved CI config, upgrade testing from v53, doc and script cleanups) contributed to faster iteration, safer upgrades, and better developer experience.
