Subject: [PATCH 01/17] Remove pro_warning_badge helper methods and constant

Remove the visual warning badge HTML generation code:
- Remove IMMEDIATE_HYDRATION_PRO_WARNING constant
- Remove pro_warning_badge_if_needed method
- Remove disabled_pro_features_message method

These methods generated a red banner in the corner of the page when
non-pro users tried to enable pro-only features. This functionality
is being removed as part of the plan to separate pro features from
the core gem.

The calls to pro_warning_badge_if_needed will be removed in
subsequent commits.

Remove the call to pro_warning_badge_if_needed in the

This is part of removing the visual warning badge that

Remove the call to pro_warning_badge_if_needed in the
generate_store_script method and simplify the handling
of the result from disable_pro_render_options_if_not_licensed.

Subject: [PATCH 04/17] Simplify ProUtils to return options directly

Refactor disable_pro_render_options_if_not_licensed to:
- Return raw options directly instead of a hash
- No longer track explicitly_disabled_pro_options
- Silently disable pro-only options when Pro is not available

This simplification removes the need to track which options
were disabled, as we no longer display a warning badge.
The method now only disables pro-only features silently,
which is the desired behavior going forward.

Subject: [PATCH 05/17] Remove explicitly_disabled_pro_options from
 RenderOptions

Simplify RenderOptions initialization by:
- Removing @explicitly_disabled_pro_options instance variable
- Removing explicitly_disabled_pro_options from attr_reader
- Directly assigning the result of disable_pro_render_options_if_not_licensed

This completes the removal of the tracking mechanism for
disabled pro options, as this information is no longer
needed without the warning badge.

Remove test contexts that verified the warning badge HTML and
logging behavior:
- Remove 'with Pro license warning' contexts from react_component tests
- Remove 'with Pro license warning' contexts from react_component_hash tests
- Remove 'with Pro license warning' contexts from redux_store tests

These tests are no longer needed since the badge functionality
has been removed. Pro features are now silently disabled when
Pro is not installed, without displaying warnings or badges.

Total: ~90 lines removed from test file

 - **Shakapacker 9.2.0 Upgrade**: Upgraded Shakapacker from 9.1.0 to 9.2.0. This minor version update adds a new `bin/shakapacker-config` utility for debugging webpack/rspack configurations with doctor mode, save mode, and stdout mode options. Supports YAML, JSON, and Node.js inspect output formats. by [justin808](https://github.com/justin808).
 
+- **Removed Pro Warning Badge**: Removed the visual warning badge that appeared when non-Pro users attempted to enable Pro-only features like `immediate_hydration`. Pro features are now silently disabled when a Pro license is not available, providing a cleaner user experience without intrusive warning banners.

Subject: [PATCH 09/17] Remove immediate_hydration config - Pro always hydrates
 immediately (#1997)

Why
Simplify configuration for pro users. Still allows override at react_component level.

Summary
Removed visual warning badges for Pro features, made immediate
hydration automatic for Pro users, and removed global config option.

Key improvements
- Automatic immediate hydration for Pro users (no config needed)
- Rails logger warnings replace visual badges for better UX
- Component-level overrides still supported via helper parameters

Impact
- Existing: Pro users unchanged; immediate hydration auto-enabled
- New: Simpler config; non-Pro get warnings in logs, not UI

Risks
Breaking: config.immediate_hydration removed from initializers
(see CHANGELOG migration steps). Security: None.

+- **`immediate_hydration` now automatically enabled for Pro users**: The `config.immediate_hydration` configuration option has been removed. Immediate hydration is now automatically enabled for React on Rails Pro users and disabled for non-Pro users, simplifying configuration while providing optimal performance by default. Component-level overrides are still supported via the `immediate_hydration` parameter on `react_component`, `redux_store`, and `stream_react_component` helpers.

 #### Breaking Changes
 
+- **`config.immediate_hydration` configuration removed**: The `config.immediate_hydration` setting in `config/initializers/react_on_rails.rb` has been removed. Immediate hydration is now automatically enabled for React on Rails Pro users and automatically disabled for non-Pro users.
+
+  **Migration steps:**
+
+  - Remove any `config.immediate_hydration = true` or `config.immediate_hydration = false` lines from your `config/initializers/react_on_rails.rb` file
+  - Pro users: No action needed - immediate hydration is now enabled automatically for optimal performance
+  - Non-Pro users: No action needed - standard hydration behavior continues to work as before
+  - Component-level overrides: You can still override behavior per-component using `react_component("MyComponent", immediate_hydration: false)` or `redux_store("MyStore", immediate_hydration: true)`
+  - If a non-Pro user explicitly sets `immediate_hydration: true` on a component, a warning will be logged and the component will fall back to standard hydration
+

 - **React on Rails Core Package**: Several Pro-only methods have been removed from the core package and are now exclusively available in the `react-on-rails-pro` package. If you're using any of the following methods, you'll need to migrate to React on Rails Pro:
   - `getOrWaitForComponent()`
   - `getOrWaitForStore()`

Subject: [PATCH 10/17] Inline immediate_hydration_enabled? method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove the intermediate immediate_hydration_enabled? helper method from
ProUtils and directly use ReactOnRails::Utils.react_on_rails_pro? instead.
This simplifies the code by removing an unnecessary layer of indirection.

The immediate_hydration_enabled? method was just a wrapper that called
support_pro_features?, which itself just calls react_on_rails_pro?.

Changes:
- Remove immediate_hydration_enabled? method from ProUtils
- Update all callers to use ReactOnRails::Utils.react_on_rails_pro? directly:
  - render_options.rb: immediate_hydration method
  - helper.rb: redux_store method
  - controller.rb: redux_store method
- Update test mocks to stub react_on_rails_pro? instead of immediate_hydration_enabled?
- Remove unnecessary test stubs in render_options_spec.rb

Subject: [PATCH 11/17] Remove unused ProUtils module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After inlining immediate_hydration_enabled?, the ProUtils module only
contains a single method (support_pro_features?) that is not used anywhere
in the codebase. This commit removes the entire module as dead code.

Changes:
- Delete lib/react_on_rails/pro_utils.rb
- Remove require "react_on_rails/pro_utils" from render_options.rb

This simplifies the codebase by removing an unnecessary abstraction layer.

Subject: [PATCH 12/17] Address review comments: Enforce immediate_hydration
 fallback for non-Pro users
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses several issues identified in code review:

1. Fixed immediate_hydration logic in RenderOptions
   - Non-Pro users setting immediate_hydration: true now get false enforced
   - Previously returned true despite warning about fallback
   - Added explicit return false to match warning message behavior

2. Added warning logic to redux_store methods
   - Both helper.rb and controller.rb now warn non-Pro users
   - Enforces fallback by overriding to false when Pro license missing
   - Provides consistent behavior with react_component helper

3. Updated test expectations
   - render_options_spec.rb now expects false (not true) for non-Pro users
   - Added comprehensive redux_store tests for warning behavior
   - Tests cover all three scenarios: true, false, and nil values

4. Clarified CHANGELOG.md
   - Explicitly states fallback is enforced (value overridden to false)
   - Covers both components and stores in the migration notes

All tests passing and RuboCop clean.

Subject: [PATCH 13/17] Refactor immediate_hydration handling and add
 deprecation warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address code review feedback:

1. Extract duplicated warning message to shared utility method
   - Add ReactOnRails::Utils.immediate_hydration_pro_license_warning helper
   - Replace inline warning messages in controller, helper, and render_options

2. Add deprecation warning for config.immediate_hydration
   - Add getter/setter methods that log deprecation warnings
   - Direct users to remove the deprecated config from initializers
   - Maintains backward compatibility while guiding migration

3. Fix inconsistent nil handling in render_options.rb
   - Simplify immediate_hydration method logic
   - Use consistent pattern: explicit value first, then default to Pro status
   - Remove confusing mix of hash access methods

All changes maintain backward compatibility while improving code
maintainability and providing better user guidance.

Subject: [PATCH 14/17] Refactor immediate_hydration logic into shared utility
 method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address code review feedback:

1. Consolidate duplicated immediate_hydration logic
   - Create ReactOnRails::Utils.normalize_immediate_hydration method
   - Replace inline logic in controller, helper, and render_options
   - Reduces code duplication from 3 locations to 1 shared method

2. Document the == true check rationale
   - Added comprehensive YARD documentation
   - Explains strict equality is intentional (not truthy check)
   - Prevents false positives from strings like "yes"/"no"
   - Type safety handled at call site by Ruby's type system

Benefits:
- Single source of truth for immediate_hydration normalization
- Easier to test and maintain
- Clear documentation of behavior
- Consistent warning messages across all entry points

Subject: [PATCH 15/17] Address code review feedback: improve deprecation
 warnings and add type validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses three issues identified during code review:

1. Deprecation warnings now use warning-once pattern
   - Added class instance variable to track if warning shown
   - Prevents log flooding when config methods accessed repeatedly
   - Uses recommended Ruby pattern instead of class variables

2. Added type validation for immediate_hydration parameter
   - Validates that value is true, false, or nil
   - Raises ArgumentError with clear message for invalid types
   - Prevents unexpected behavior from truthy non-boolean values

3. Fixed CHANGELOG formatting for consistency
   - Changed [PR 1993] to [PR #1993] to match other entries

All changes include comprehensive test coverage and pass RuboCop.

Subject: [PATCH 16/17] Implement code review recommendations: improve
 thread-safety, tests, and deprecation detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add comprehensive unit tests for ReactOnRails::Utils.normalize_immediate_hydration
  - Tests for Pro/non-Pro license scenarios
  - Tests for invalid value type validation
  - Tests for warning messages with component/store names

- Add tests for deprecated config.immediate_hydration setter/getter
  - Tests for deprecation warnings on both setter and getter
  - Tests for warning suppression (only warns once)
  - Tests for setter/getter interaction scenarios

- Fix thread-safety of deprecation warning flag
  - Implement Mutex-based synchronization for @immediate_hydration_warned flag
  - Ensures safe access in multi-threaded environments (Puma, Sidekiq, etc.)

- Add doctor.rb detection for deprecated config.immediate_hydration
  - Helps users identify and remove deprecated configuration during migration
  - Provides clear guidance on automatic behavior for Pro users

- Remove unnecessary blank line in controller.rb for cleaner code

All tests passing. Zero RuboCop violations.

Subject: [PATCH 17/17] Make generated_component_packs_loading_strategy default
 based on Pro license
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Pro users (Shakapacker >= 8.2.0): defaults to :async for optimal performance
- Non-Pro users (Shakapacker >= 8.2.0): defaults to :defer for compatibility
- Older Shakapacker versions: continues to default to :sync (unchanged)

This aligns with the immediate_hydration behavior where Pro features
are automatically enabled based on license detection, providing the
best default experience for each user type.

Updated tests to verify Pro/non-Pro default behaviors separately while
maintaining tests for explicit value overrides.

 - **`immediate_hydration` now automatically enabled for Pro users**: The `config.immediate_hydration` configuration option has been removed. Immediate hydration is now automatically enabled for React on Rails Pro users and disabled for non-Pro users, simplifying configuration while providing optimal performance by default. Component-level overrides are still supported via the `immediate_hydration` parameter on `react_component`, `redux_store`, and `stream_react_component` helpers.

This provides optimal performance for Pro users while maintaining compatibility for non-Pro users. You can still explicitly set the strategy in your configuration.
