Changelog

Sourced from actionview's changelog.

Rails 8.1.4 (September 24, 2026)

• Fix non-ASCII strict locals defaults rendering as mojibake.

  When a template declared a non-ASCII default in its locals: magic comment and its body was ASCII-only, the handler returned ASCII-8BIT code and the compiled method definition was retagged with it, corrupting the default.

  Carlos Daniel Pohlod

• Fix the :ruby render tracker not being registered for ERB templates when eager_load is enabled.

  Gabriel Quaresma

• Fix Encoding::CompatibilityError when digesting templates with non-ASCII content via DependencyTracker::RubyTracker.

  File-backed templates are loaded as ASCII-8BIT. RubyTracker now passes template.encode! to the handler (matching Template#compiled_source) so handlers such as Haml/Temple can concatenate static UTF-8 strings without raising. Fixes #58203.

  Edil Talantbek uulu

• Fix week_field to not emit invalid week strings at ISO year boundaries.

  Kenta Ishizaki

• Fix ActionView::TestCase#render to reset rendered. The behavior was changed when memoization was added in #51093. Now it once again conforms to the documentation.

  Jeroen Versteeg

• Fix FormBuilder#to_partial_path returning nil for subclasses whose name does not end in Builder.

  Kenta Ishizaki

• Fix collection_radio_buttons and collection_check_boxes generating a label for attribute that does not match the input id when a collection value is nil.
