Good morning. This is your Rails development briefing for May 19th, 2026.
Jean Boussier merged improvements to HTTP caching with a new optional last_modified parameter for http_cache_forever. The enhancement allows developers to specify a relevant timestamp instead of defaulting to January 1st, 2011, and has been implemented in Active Storage's ProxyController.
Fatkodima merged a fix for Active Storage attachment preservation when converting records using Single Table Inheritance. This resolves issue #45778 where attachment changes were lost during STI class conversions.
Tahsin352 merged a bug fix for the number_to_phone helper, correcting a false-positive in start_with_delimiter detection when phone numbers coincidentally begin with delimiter strings.
Joshua Young merged a Ruby 3.4 compatibility fix, adding proper block parameter handling to ReflectionProxy to eliminate strict_unused_block warnings.
Ayush Newatia merged substantial updates to the Rails on Rack guide, including improved documentation structure, new middleware stack information, and sections on custom middleware integration.
