```
Timo Schilling
Remove deprecate ActiveSupport::Multibyte::Unicode.default_normalization_form.

Rafael Mendonça França
Invoking Object#with_options without a &block argument returns the
ActiveSupport::OptionMerger instance.

Rails.application.executor hooks can now be called around every test
This helps to better simulate request or job local state being reset around tests and prevents state
leaking from one test to another.
However it requires the executor hooks executed in the test environment to be re-entrant.
To enable this, set config.active_support.executor_around_test_case = true (this is the default in Rails 7).
Jean Boussier
ActiveSupport::DescendantsTracker now mostly delegate to Class#descendants on Ruby 3.1
Ruby now provides a fast Class#descendants making ActiveSupport::DescendantsTracker mostly useless.
As a result the following methods are deprecated:
- ActiveSupport::DescendantsTracker.direct_descendants
- ActiveSupport::DescendantsTracker#direct_descendants
Jean Boussier
Fix the Digest::UUID.uuid_from_hash behavior for namespace IDs that are different from the ones defined on Digest::UUID.
The new behavior will be enabled by setting the
config.active_support.use_rfc4122_namespaced_uuids option to true
and is the default for new apps.
The old behavior is the default for upgraded apps and will output a
deprecation warning every time a value that is different than one of
the constants defined on the Digest::UUID extension is used as the
namespace ID.
Alex Robbin, Erich Soares Machado, Eugene Kenny
ActiveSupport::Inflector::Inflections#clear(:acronyms) is now supported,
and inflector.clear / inflector.clear(:all) also clears acronyms.
Alex Ghiculescu, Oliver Peate

Clear secure password cache if password is set to nil
Before:
user.password = 'something'
user.password = nil
user.password # => 'something'
Now:
user.password = 'something'
user.password = nil
user.password # => nil
Markus Doits

Active Record

Remove deprecated ActiveRecord::DatabaseConfigurations::DatabaseConfig#spec_name.
Rafael Mendonça França
Remove deprecated ActiveRecord::Connection#in_clause_length.
Rafael Mendonça França
Remove deprecated ActiveRecord::Connection#allowed_index_name_length.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base#remove_connection.

Load STI Models in fixtures
Data from Fixtures now loads based on the specific class for models with
Single Table Inheritance. This affects enums defined in subclasses, previously
the value of these fields was not parsed and remained nil
Andres Howard
#authenticate returns false when the password is blank instead of raising an error.
Muhammad Muhammad Ibrahim
Fix ActiveRecord::QueryMethods#in_order_of behavior for integer enums.
ActiveRecord::QueryMethods#in_order_of didn't work as expected for enums stored as integers in the database when passing an array of strings or symbols as the order argument. This unexpected behavior occurred because the string or symbol values were not casted to match the integers in the database.
The following example now works as expected:
```
class Book < ApplicationRecord
  enum status: [:proposed, :written, :published]
end

Book.in_order_of(:status, %w[written published proposed])
```
Alexandre Ruban
Ignore persisted in-memory records when merging target lists.
Kevin Sjöberg
Add a new option :update_only to upsert_all to configure the list of columns to update in case of conflict.
Before, you could only customize the update SQL sentence via :on_duplicate. There is now a new option :update_only that lets you provide a list of columns to update in case of conflict:
```
Commodity.upsert_all(
  [
    { id: 2, name: "Copper", price: 4.84 },
    { id: 4, name: "Gold", price: 1380.87 },
    { id: 6, name: "Aluminium", price: 0.35 }
  ],
  update_only: [:price] # Only prices will be updated
)
```
Jorge Manrubia
Remove deprecated ActiveRecord::Result#map! and ActiveRecord::Result#collect!.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base.configurations.to_h.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base.configurations.default_hash.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base.arel_attribute.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base.connection_config.
Rafael Mendonça França

Filter attributes in SQL logs

Previously, SQL queries in logs containing ActiveRecord::Base.filter_attributes were not filtered.

Now, the filter attributes will be masked [FILTERED] in the logs when prepared_statement is enabled.

# Before:
  Foo Load (0.2ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "hello"], ["LIMIT", 1]]

# After:
  Foo Load (0.5ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "[FILTERED]"], ["LIMIT", 1]]

Merging conditions on the same column no longer maintain both conditions,
and will be consistently replaced by the latter condition.

# Rails 6.1 (IN clause is replaced by merger side equality condition)
Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
# Rails 6.1 (both conflict conditions exists, deprecated)
Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => []
# Rails 6.1 with rewhere to migrate to Rails 7.0's behavior
Author.where(id: david.id..mary.id).merge(Author.where(id: bob), rewhere: true) # => [bob]
# Rails 7.0 (same behavior with IN clause, mergee side condition is consistently replaced)
Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => [bob]

*Rafael Mendonça França*

Remove deprecated support to Model.reorder(nil).first to search using non-deterministic order.
Rafael Mendonça França
Remove deprecated rake tasks:
- db:schema:load_if_ruby
- db:structure:dump
- db:structure:load
- db:structure:load_if_sql
- db:structure:dump:#{name}
- db:structure:load:#{name}
- db:test:load_structure
- db:test:load_structure:#{name}
Rafael Mendonça França
Remove deprecated DatabaseConfig#config method.
Rafael Mendonça França
Rollback transactions when the block returns earlier than expected.
Before this change, when a transaction block returned early, the transaction would be committed.
The problem is that timeouts triggered inside the transaction block was also making the incomplete transaction
to be committed, so in order to avoid this mistake, the transaction block is rolled back.
Rafael Mendonça França
Add middleware for automatic shard swapping.
Provides a basic middleware to perform automatic shard swapping. Applications will provide a resolver which will determine for an individual request which shard should be used. Example:
```
config.active_record.shard_resolver = ->(request) {
  subdomain = request.subdomain
  tenant = Tenant.find_by_subdomain!(subdomain)
  tenant.shard
}
```
See guides for more details.
Eileen M. Uchitelle, John Crepezzi
Remove deprecated support to pass a column to type_cast.
Rafael Mendonça França
Remove deprecated support to type cast to database values ActiveRecord::Base objects.
Rafael Mendonça França
Remove deprecated support to quote ActiveRecord::Base objects.
Rafael Mendonça França
Remove deprecacated support to resolve connection using "primary" as connection specification name.
Rafael Mendonça França
Remove deprecation warning when using :interval column is used in PostgreSQL database.
Now, interval columns will return ActiveSupport::Duration objects instead of strings.
To keep the old behavior, you can add this line to your model:
```
attribute :column, :string
```
Rafael Mendonça França
Remove deprecated support to YAML load ActiveRecord::Base instance in the Rails 4.2 and 4.1 formats.
Rafael Mendonça França
Remove deprecated option :spec_name in the configs_for method.
Rafael Mendonça França
Remove deprecated ActiveRecord::Base.allow_unsafe_raw_sql.
Rafael Mendonça França
Fix regression bug that caused ignoring additional conditions for preloading has_many-through relations.

Fix has_many inversing recursion on models with recursive associations.
Gannon McGibbon

Add accepts_nested_attributes_for support for delegated_type

class Entry < ApplicationRecord
  delegated_type :entryable, types: %w[ Message Comment ]
  accepts_nested_attributes_for :entryable
end

entry = Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
# => #<Entry:0x00>
# id: 1
# entryable_id: 1,
# entryable_type: 'Message'
# ...>

entry.entryable
# => #<Message:0x01>
# id: 1
# content: 'Hello world'
# ...>

Previously it would raise an error:

Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
# ArgumentError: Cannot build association `entryable'. Are you trying to build a polymorphic one-to-one association?

Sjors Baltus

Use subquery for DELETE with GROUP_BY and HAVING clauses.
Prior to this change, deletes with GROUP_BY and HAVING were returning an error.
After this change, GROUP_BY and HAVING are valid clauses in DELETE queries, generating the following query:
```
DELETE FROM "posts" WHERE "posts"."id" IN (
    SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id" GROUP BY "posts"."id" HAVING (count(comments.id) >= 2))
)  [["flagged", "t"]]
```
Ignacio Chiazzo Cardarello

Use subquery for UPDATE with GROUP_BY and HAVING clauses.

Prior to this change, updates with GROUP_BY and HAVING were being ignored, generating a SQL like this:

UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
    SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
)  [["flagged", "t"]]

After this change, GROUP_BY and HAVING clauses are used as a subquery in updates, like this:

UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
    SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
    GROUP BY posts.id HAVING (count(comments.id) >= 2)
)  [["flagged", "t"]]

Ignacio Chiazzo Cardarello

Add support for setting the filename of the schema or structure dump in the database config.
Applications may now set their the filename or path of the schema / structure dump file in their database configuration.
```
production:
  primary:
    database: my_db
    schema_dump: my_schema_dump_filename.rb
  animals:
    database: animals_db
    schema_dump: false
```
The filename set in schema_dump will be used by the application. If set to false the schema will not be dumped. The database tasks are responsible for adding the database directory to the filename. If a full path is provided, the Rails tasks will use that instead of ActiveRecord::DatabaseTasks.db_dir.
Eileen M. Uchitelle, Ryan Kerr
Add ActiveRecord::Base.prohibit_shard_swapping to prevent attempts to change the shard within a block.
John Crepezzi, Eileen M. Uchitelle
Filter unchanged attributes with default function from insert query when partial_inserts is disabled.
Akshay Birajdar, Jacopo Beschi
Add support for FILTER clause (SQL:2003) to Arel.
Currently supported by PostgreSQL 9.4+ and SQLite 3.30+.
Andrey Novikov
Automatically set timestamps on record creation during bulk insert/upsert
Prior to this change, only updates during an upsert operation (e.g. upsert_all) would touch timestamps (updated_{at,on}). Now, record creations also touch timestamp columns ({created,updated}_{at,on}).
This behaviour is controlled by the <model>.record_timestamps config, matching the behaviour of create, update, etc. It can also be overridden by using the record_timestamps: keyword argument.
Note that this means upsert_all on models with record_timestamps = false will no longer touch updated_{at,on} automatically.
Sam Bostock
Don't require role when passing shard to connected_to.
connected_to can now be called with a shard only. Note that role is still inherited if connected_to calls are nested.
Eileen M. Uchitelle
Add option to lazily load the schema cache on the connection.
Previously, the only way to load the schema cache in Active Record was through the Railtie on boot. This option provides the ability to load the schema cache on the connection after it's been established. Loading the cache lazily on the connection can be beneficial for Rails applications that use multiple databases because it will load the cache at the time the connection is established. Currently Railties doesn't have access to the connections before boot.
To use the cache, set config.active_record.lazily_load_schema_cache = true in your application configuration. In addition a schema_cache_path should be set in your database configuration if you don't want to use the default "db/schema_cache.yml" path.
Eileen M. Uchitelle
Allow automatic inverse_of detection for associations with scopes.
Automatic inverse_of detection now works for associations with scopes. For
example, the comments association here now automatically detects
inverse_of: :post, so we don't need to pass that option:
```
class Post < ActiveRecord::Base
  has_many :comments, -> { visible }
end

class Comment < ActiveRecord::Base
  belongs_to :post
end
```
Note that the automatic detection still won't work if the inverse
association has a scope. In this example a scope on the post association
would still prevent Rails from finding the inverse for the comments
association.
This will be the default for new apps in Rails 7. To opt in:
```
config.active_record.automatic_scope_inversing = true
```
Daniel Colson, Chris Bloom
Accept optional transaction args to ActiveRecord::Locking::Pessimistic#with_lock
#with_lock now accepts transaction options like requires_new:,
isolation:, and joinable:
Adds support for deferrable foreign key constraints in PostgreSQL.
By default, foreign key constraints in PostgreSQL are checked after each statement. This works for most use cases,
but becomes a major limitation when creating related records before the parent record is inserted into the database.
One example of this is looking up / creating a person via one or more unique alias.
```
Person.transaction do
  alias = Alias
    .create_with(user_id: SecureRandom.uuid)
    .create_or_find_by(name: "DHH")

  person = Person
    .create_with(name: "David Heinemeier Hansson")
    .create_or_find_by(id: alias.user_id)
end
```
Using the default behavior, the transaction would fail when executing the first INSERT statement.
By passing the :deferrable option to the add_foreign_key statement in migrations, it's possible to defer this
check.
```
add_foreign_key :aliases, :person, deferrable: true
```
Passing deferrable: true doesn't change the default behavior, but allows manually deferring the check using
SET CONSTRAINTS ALL DEFERRED within a transaction. This will cause the foreign keys to be checked after the
transaction.
It's also possible to adjust the default behavior from an immediate check (after the statement), to a deferred check
(after the transaction):
```
add_foreign_key :aliases, :person, deferrable: :deferred
```
Benedikt Deicke

Allow configuring Postgres password through the socket URL.

For example:

ActiveRecord::DatabaseConfigurations::UrlConfig.new(
  :production, :production, 'postgres:///?user=user&password=secret&dbname=app', {}
).configuration_hash

will now return,

{ :user=>"user", :password=>"secret", :dbname=>"app", :adapter=>"postgresql" }

Abeid Ahmed

PostgreSQL: support custom enum types
In migrations, use create_enum to add a new enum type, and t.enum to add a column.
```
def up
  create_enum :mood, ["happy", "sad"]

  change_table :cats do |t|
    t.enum :current_mood, enum_type: "mood", default: "happy", null: false
  end
end
```
Enums will be presented correctly in schema.rb. Note that this is only supported by
the PostgreSQL adapter.
Alex Ghiculescu
Avoid COMMENT statements in PostgreSQL structure dumps
COMMENT statements are now omitted from the output of db:structure:dump when using PostgreSQL >= 11.
This allows loading the dump without a pgsql superuser account.
Fixes #36816, #43107.
Janosch Müller
Add support for generated columns in PostgreSQL adapter
Generated columns are supported since version 12.0 of PostgreSQL. This adds
support of those to the PostgreSQL adapter.
```
create_table :users do |t|
  t.string :name
  t.virtual :name_upcased, type: :string, as: 'upper(name)', stored: true
end
```

Action View

Support fields model: [@nested, @model] the same way as form_with model: [@nested, @model].
Sean Doyle

Infer HTTP verb [method] from a model or Array with model as the first
argument to button_to when combined with a block:

button_to(Workshop.find(1)){ "Update" }
#=> <form method="post" action="/workshops/1" class="button_to">
#=>   <input type="hidden" name="_method" value="patch" autocomplete="off" />
#=>   <button type="submit">Update</button>
#=> </form>

button_to([ Workshop.find(1), Session.find(1) ]) { "Update" }
#=> <form method="post" action="/workshops/1/sessions/1" class="button_to">
#=>   <input type="hidden" name="_method" value="patch" autocomplete="off" />
#=>   <button type="submit">Update</button>
#=> </form>

Sean Doyle

Support passing a Symbol as the first argument to FormBuilder#button:

form.button(:draft, value: true)
# => <button name="post[draft]" value="true" type="submit">Create post</button>

form.button(:draft, value: true) do
  content_tag(:strong, "Save as draft")
end
# =>  <button name="post[draft]" value="true" type="submit">
#       <strong>Save as draft</strong>
#     </button>

Sean Doyle

Introduce the field_name view helper, along with the
FormBuilder#field_name counterpart:

form_for @post do |f|
  f.field_tag :tag, name: f.field_name(:tag, multiple: true)
  # => <input type="text" name="post[tag][]">
end

Sean Doyle

Execute the ActionView::Base.field_error_proc within the context of the
ActionView::Base instance:

config.action_view.field_error_proc = proc { |html| content_tag(:div, html, class: "field_with_errors") }

Sean Doyle

Add support for button_to ..., authenticity_token: false

button_to "Create", Post.new, authenticity_token: false
# => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button></form>

button_to "Create", Post.new, authenticity_token: true
# => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="abc123..." autocomplete="off" /></form>

button_to "Create", Post.new, authenticity_token: "secret"
# => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="secret" autocomplete="off" /></form>

Sean Doyle

Support rendering <form> elements without [action] attributes by:
- form_with url: false or form_with ..., html: { action: false }
- form_for ..., url: false or form_for ..., html: { action: false }
- form_tag false or form_tag ..., action: false
- button_to "...", false or button_to(false) { ... }
Sean Doyle

Add :day_format option to date_select

date_select("article", "written_on", day_format: ->(day) { day.ordinalize })
# generates day options like <option value="1">1st</option>\n<option value="2">2nd</option>...

Shunichi Ikegami

Allow link_to helper to infer link name from Model#to_s when it
is used with a single argument:
```
link_to @profile
#=> <a href="/profiles/1">Eileen</a>
```
This assumes the model class implements a to_s method like this:
```
class Profile < ApplicationRecord
  # ...
  def to_s
    name
  end
end
```
Previously you had to supply a second argument even if the Profile
model implemented a #to_s method that called the name method.
```
link_to @profile, @profile.name
#=> <a href="/profiles/1">Eileen</a>
```
Olivier Lacan

Support svg unpaired tags for tag helper.

tag.svg { tag.use('href' => "#cool-icon") }
# => <svg><use href="#cool-icon"></svg>

Allow permitting numeric params.
Previously it was impossible to permit different fields on numeric parameters.
After this change you can specify different fields for each numbered parameter.
For example params like,
```
book: {
        authors_attributes: {
          '0': { name: "William Shakespeare", age_of_death: "52" },
          '1': { name: "Unattributed Assistant" },
          '2': "Not a hash",
          'new_record': { name: "Some name" }
        }
      }
```
Before you could permit name on each author with,
permit book: { authors_attributes: [ :name ] }
After this change you can permit different keys on each numbered element,
permit book: { authors_attributes: { '1': [ :name ], '0': [ :name, :age_of_death ] } }

Action Cable

The Action Cable client now ensures successful channel subscriptions:
- The client maintains a set of pending subscriptions until either
  the server confirms the subscription or the channel is torn down.
- Rectifies the race condition where an unsubscribe is rapidly followed
  by a subscribe (on the same channel identifier) and the requests are
  handled out of order by the ActionCable server, thereby ignoring the
  subscribe command.
