## Rails 8.0.0 (November 07, 2024) ##

## Rails 8.0.0.rc2 (October 30, 2024) ##

*   No changes.


## Rails 8.0.0.rc1 (October 19, 2024) ##

*   Remove deprecated support to passing an array of strings to `ActiveSupport::Deprecation#warn`.

    *Rafael Mendonça França*

*   Remove deprecated support to setting `attr_internal_naming_format` with a `@` prefix.

    *Rafael Mendonça França*

*   Remove deprecated `ActiveSupport::ProxyObject`.

    *Rafael Mendonça França*

*   Don't execute i18n watcher on boot. It shouldn't catch any file changes initially,
    and unnecessarily slows down boot of applications with lots of translations.

    *Gannon McGibbon*, *David Stosik*

*   Fix `ActiveSupport::HashWithIndifferentAccess#stringify_keys` to stringify all keys not just symbols.

    Previously:

    ```ruby
    { 1 => 2 }.with_indifferent_access.stringify_keys[1] # => 2
    ```

    After this change:

    ```ruby
    { 1 => 2 }.with_indifferent_access.stringify_keys["1"] # => 2
    ```

    This change can be seen as a bug fix, but since it behaved like this for a very long time, we're deciding
    to not backport the fix and to make the change in a major release.

## Rails 8.0.0.beta1 (September 26, 2024) ##

*   Include options when instrumenting `ActiveSupport::Cache::Store#delete` and `ActiveSupport::Cache::Store#delete_multi`.

    *Adam Renberg Tamm*

*   Print test names when running `rails test -v` for parallel tests.

    *John Hawthorn*, *Abeid Ahmed*

*   Deprecate `Benchmark.ms` core extension.

    The `benchmark` gem will become bundled in Ruby 3.5

    *Earlopain*

*   `ActiveSupport::TimeWithZone#inspect` now uses ISO 8601 style time like `Time#inspect`

    *John Hawthorn*

*   `ActiveSupport::ErrorReporter#report` now assigns a backtrace to unraised exceptions.

    Previously reporting an un-raised exception would result in an error report without
    a backtrace. Now it automatically generates one.

    *Jean Boussier*

*   Add `escape_html_entities` option to `ActiveSupport::JSON.encode`.

    This allows for overriding the global configuration found at
    `ActiveSupport.escape_html_entities_in_json` for specific calls to `to_json`.

    This should be usable from controllers in the following manner:
    ```ruby
    class MyController < ApplicationController
      def index
        render json: { hello: "world" }, escape_html_entities: false
      end
    end
    ```

    *Nigel Baillie*

*   Raise when using key which can't respond to `#to_sym` in `EncryptedConfiguration`.

    As is the case when trying to use an Integer or Float as a key, which is unsupported.

    *zzak*

*   Deprecate addition and since between two `Time` and `ActiveSupport::TimeWithZone`.

    Previously adding time instances together such as `10.days.ago + 10.days.ago` or `10.days.ago.since(10.days.ago)` produced a nonsensical future date. This behavior is deprecated and will be removed in Rails 8.1.

    *Nick Schwaderer*

*   Support rfc2822 format for Time#to_fs & Date#to_fs.

    *Akshay Birajdar*

*   Optimize load time for `Railtie#initialize_i18n`. Filter `I18n.load_path`s passed to the file watcher to only those
    under `Rails.root`. Previously the watcher would grab all available locales, including those in gems
    which do not require a watcher because they won't change.

    *Nick Schwaderer*

*   Add a `filter` option to `in_order_of` to prioritize certain values in the sorting without filtering the results
    by these values.

    *Igor Depolli*

*   Improve error message when using `assert_difference` or `assert_changes` with a
    proc by printing the proc's source code (MRI only).

    *Richard Böhme*, *Jean Boussier*

*   Add a new configuration value `:zone` for `ActiveSupport.to_time_preserves_timezone` and rename the previous `true` value to `:offset`. The new default value is `:zone`.

    *Jason Kim*, *John Hawthorn*

*   Align instrumentation `payload[:key]` in ActiveSupport::Cache to follow the same pattern, with namespaced and normalized keys.

    *Frederik Erbs Spang Thomsen*

*   Fix `travel_to` to set usec 0 when `with_usec` is `false` and the given argument String or DateTime.
