We had 22 Ruby on Rails contributors this week, including a first-time contributor. Thanks!

Improved
Permit loads while queries are running

Permit loads while queries are running

A query may wait on a database-level lock, which could lead to a deadlock between threads. No one likes deadlocks. They are the stuff of developers' nightmares! 💀
Remove unnecessary `respond_to?(:indexes)` checks

Remove unnecessary `respond_to?(:indexes)` checks

All database adapters have implemented the `indexes` method and support was removed. Some concerns were raised (from the dead? 💀), but the contributor demonstrated the requirement for database adapters to support `indexes` in early versions.

Fixed
Clear the correct query cache

Clear the correct query cache

The correct query cache was not being cleared. The author mentioned that this bug was happening in Sidekiq as well. Check out the details!
Fix HABTM associations

Use constants, strings, and symbols to express your HABTM associations. Check out the commit for more details.
