-## HELP!
+## Apartment drop in replacement gem
 
-In order to help drive the direction of development and clean up the codebase, we'd like to take a poll

-this poll, we'd greatly appreciated it.

-## Excessive Memory Issues on ActiveRecord 4.x

-> If you're noticing ever growing memory issues (ie growing with each tenant you add)
-> when using Apartment, that's because there's [an issue](https://github.com/rails/rails/issues/19578)
-> with how ActiveRecord maps Postgresql data types into AR data types.
-> This has been patched and will be released for AR 4.2.2. It's apparently hard
-> to backport to 4.1 unfortunately.
-> If you're noticing high memory usage from ActiveRecord with Apartment please upgrade.
