Posted by gregmolnar

Hello fellow Rubyist!

This is Greg, bringing the latest news about the Rails framework!

Fill a Trix editor easily in system tests

ActionDispatch::SystemTestCase#fill_in_rich_text_area  can  locate and fill a Trix editor with the given HTML in your system tests.

ActiveRecord#respond_to? performance improvements

The changes introduced by this pull request made ActiveRecord#respond_to?  1.5x faster and it also no longer allocates strings.

Permit uploading files larger than 5 GB to S3

If you are using S3 with Active Storage, now you can upload large files and the services will transparently switch to streaming.

HashWithIndifferentAccess#initialize performance improvement

With this change, a quite expensive to_hash call is bypassed in the constructor if we are already dealing with a hash.

Expose mailbox_for method in ApplicationMailbox

Rails 6 is bringing Action Mailbox and with this change, it will be possible to check which mailbox an email is routed to without processing it.
