CHANGELOG - rails 8.0.3 documentation

`Rails` 8.0.3 (September 22, 2025)¶ ↑

Fix label with for option not getting prefixed by form namespace value

Abeid Ahmed, Hartley McGuire
Fix javascript_include_tag type option to accept either strings and symbols.
```
javascript_include_tag "application", type: :module
javascript_include_tag "application", type: "module"
```
Previously, only the string value was recognized.

Jean Boussier
Fix excerpt helper with non-whitespace separator.

Jonathan Hefner

Respect html_options[:form] when collection_checkboxes generates the hidden <input>.

Riccardo Odone
Layouts have access to local variables passed to render.

This fixes #31680 which was a regression in Rails 5.1.

Mike Dalessio
Argument errors related to strict locals in templates now raise an ActionView::StrictLocalsError, and all other argument errors are reraised as-is.

Previously, any ArgumentError raised during template rendering was swallowed during strict local error handling, so that an ArgumentError unrelated to strict locals (e.g., a helper method invoked with incorrect arguments) would be replaced by a similar ArgumentError with an unrelated backtrace, making it difficult to debug templates.

Now, any ArgumentError unrelated to strict locals is reraised, preserving the original backtrace for developers.

Also note that ActionView::StrictLocalsError is a subclass of ArgumentError, so any existing code that rescues ArgumentError will continue to work.

Fixes #52227.

Mike Dalessio
Fix stack overflow error in dependency tracker when dealing with circular dependencies

Jean Boussier

Fix a crash in ERB template error highlighting when the error occurs on a line in the compiled template that is past the end of the source template.

Martin Emde
Improve reliability of ERB template error highlighting. Fix infinite loops and crashes in highlighting and improve tolerance for alternate ERB handlers.

Martin Emde

Remove deprecated support to passing a content to void tag elements on the tag builder.

Rafael Mendonça França
Remove deprecated support to passing nil to the model: argument of form_with.

Rafael Mendonça França

Enable DependencyTracker to evaluate renders with trailing interpolation.
```
<%= render "maintenance_tasks/runs/info/#{run.status}" %>
```
Previously, the DependencyTracker would ignore this render, but now it will mark all partials in the "maintenance_tasks/runs/info" folder as dependencies.

Hartley McGuire
Rename text_area methods into textarea

Old names are still available as aliases.

Sean Doyle
Rename check_box* methods into checkbox*.

Old names are still available as aliases.
