Rails merges a critical fix for parallel test database leaks that were orphaning per-worker databases across PostgreSQL and MySQL test runs.

The rails/rails team shipped a fix [1] that makes `use_postgresql` and `use_mysql2` test helpers automatically drop temporary databases created inside their blocks, solving a long-standing problem where per-PID and per-worker databases lingered after test runs completed. Without this change, `rails db:drop` couldn't clean up what `ActiveRecord::TestDatabases.create_and_load_schema` created because those databases never made it into `config/database.yml`. The merge [2] updates existing callers to use the new block pattern. On the maintenance side, rails also patched a console subprocess leak in FullStackConsoleTest [3], ensuring spawned processes get cleaned up properly. A separate fix [4] landed for PostgreSQL schema dumping to preserve index opclas from different schemas, closing a gap in migration reliability. In the ecosystem, tailwindcss-rails bumped its dependency [5] from version 4.2.4 to 4.3.0, picking up the latest Tailwind CSS improvements and keeping the rail-managed build chain current.
