Hi, this is Greg, bringing you the latest changes in Rails.

Remove default reliance on Sass and CSS generators

Due to Saas has chosen to focus exclusively on dart-saas, Rails is decreasing its reliance on it. Besides that, this PR also removes the per model css file generation.

Avoid use of exceptions to detect invalid floats

This PR Improves the performance of ActiveSupport::NumberHelper and ActionView::Helpers::NumberHelper formatters by avoiding the use of exceptions as flow control.

Make preload_link_tag work with images

Prior to this change, preload_link_tag with an image would generate a tag without an as attribute. If the as attribute doesn’t get set, browsers tend to ignore the link tag, making the tag useless. This change fixes the issue.

Add ability to ignore tables in the schema cache

In cases where an application uses pt-osc or lhm they may have temporary tables being used for migrations. Those tables shouldn’t be included by the schema cache because it makes the cache bigger and after this change, on_e can set config.active_record.schema_cache_ignored_tables_ to an array of tables or regex’s.
