4.21.0

• Avoid NameError during eager loading when components include modules with temporary names.

  Joel Hawksley

• Avoid repeated scanning of unterminated ERB tags during cache dependency discovery.

  Joel Hawksley

• Skip dependency compilation for static ERB markup and literal templates while preserving helper-rendered component tracking.

  Joel Hawksley

• Track helper-rendered component cache dependencies, enforce single-use instances on cache hits, and emit one render notification per self-cached render.

  Joel Hawksley

• Resolve symbolic translation defaults in sidecars, restore request URL state in tests, and refresh inherited templates whenever template reloading is enabled.

  Joel Hawksley

• Reuse existing GitHub releases when retrying a failed gem publish.

  Joel Hawksley

• Prevent self-cache key collisions and track component references in views and format-specific partial dependencies.

  Joel Hawksley

• Isolate preview and request parameters, honor preview locale callbacks, restore controller view contexts, and accept nil translation keys.

  Joel Hawksley

• Honor negative generator flags and preserve pre-release versions throughout release automation. Report gem publishing failures.

  Joel Hawksley

• Fix fragment cache collisions after render_parent, missing relative-partial and inherited-template dependencies, format fallback cache collisions, and stale cached output after development template edits.

  Joel Hawksley

• Fix template method collisions between formats and variants, preserve default slot state, and copy collection spacer slots independently.

  Joel Hawksley

• Apply --skip-suffix to all generated component files and restore full request URLs after with_request_url blocks.

  Joel Hawksley

• Reset the assertion page when rendering a preview so assertions inspect the latest output.

  Joel Hawksley

• Rediscover templates after development changes, including added or removed variants and parent templates.

  Joel Hawksley

• Include all requested variants in output cache keys, preserving fallback order.

  Joel Hawksley

• Resolve cache dependencies in their Ruby lexical namespaces and component template scopes.

  Joel Hawksley

• Keep default slot configuration isolated between parent components and subclasses.

  Joel Hawksley

• Preserve the calling view's translation scope when a component returns cached output or rejects content.

  Joel Hawksley

• Reduce rendering and collection overhead, and speed up eager loading by sharing template-path parsing and avoiding redundant template and ancestor checks.

  Joel Hawksley

• Speed up eager loading by sharing source-file reads between template compilation and cache digest precomputation, and reduce nested-render and default-slot lookup overhead.

  Joel Hawksley

• Speed up eager loading by sharing sidecar directory listings during compilation, and reduce per-render state reset overhead.

  Joel Hawksley

• Ignore unresolved partial dependencies inferred from dynamic renders, such as render UI.button, without requiring configuration for component facades. Real partials and explicit dependencies are preserved.

  Joel Hawksley

• Raise ViewComponent::UnknownConfigOptionError when setting a config.view_component option that doesn't exist, rather than ignoring it. This includes options renamed or removed in 4.0, such as preview_controller (now previews.controller), and the error names the replacement. Replacing previews or generate with a hash preserves this validation, including through Hash mutation methods such as merge!, update, store, and replace.
