This was + affecting certain databases that use specific column types. + + Fixes #6763. + + *Alfred Wong* + +* rescue from all exceptions in `ConnectionManagement#call` + + Fixes #11497. + + As `ActiveRecord::ConnectionAdapters::ConnectionManagement` middleware does + not rescue from Exception (but only from StandardError), the Connection + Pool quickly runs out of connections when multiple erroneous Requests come + in right after each other. + + Rescuing from all exceptions and not just StandardError, fixes this + behaviour. + + *Vipul A M* + +* `change_column` for PostgreSQL adapter respects the `:array` option. + + *Yves Senn* + +* Remove deprecation warning from `attribute_missing` for attributes that are columns. + + *Arun Agrawal* + +* Remove extra decrement of transaction deep level. + + Fixes #4566. + + *Paul Nikitochkin* + +* Reset @column_defaults when assigning `locking_column`. + We had a potential problem. For example: + + class Post < ActiveRecord::Base + self.column_defaults # if we call this unintentionally before setting locking_column ... + self.locking_column = 'my_locking_column' + end + + Post.column_defaults["my_locking_column"] + => nil # expected value is 0 ! + + *kennyj* + +* Remove extra select and update queries on save/touch/destroy ActiveRecord model + with belongs to reflection with option `touch: true`. + + Fixes #11288. + + *Paul Nikitochkin* + +* Remove deprecated nil-passing to the following `SchemaCache` methods: + `primary_keys`, `tables`, `columns` and `columns_hash`. + + *Yves Senn* + +* Remove deprecated block filter from `ActiveRecord::Migrator#migrate`. + + *Yves Senn* + +* Remove deprecated String constructor from `ActiveRecord::Migrator`. + + *Yves Senn* + +* Remove deprecated `scope` use without passing a callable object. + + *Arun Agrawal* + +* Remove deprecated `transaction_joinable=` in favor of `begin_transaction` + with `:joinable` option. + + *Arun Agrawal* + +* Remove deprecated `decrement_open_transactions`. + + *Arun Agrawal* + +* Remove deprecated `increment_open_transactions`. + + *Arun Agrawal* + +* Remove deprecated `PostgreSQLAdapter#outside_transaction?` + method. You can use `#transaction_open?` instead. + + *Yves Senn* + +* Remove deprecated `ActiveRecord::Fixtures.find_table_name` in favor of + `ActiveRecord::Fixtures.default_fixture_model_name`. + + *Vipul A M* + +* Removed deprecated `columns_for_remove` from `SchemaStatements`. + + *Neeraj Singh* + +* Remove deprecated `SchemaStatements#distinct`. + + *Francesco Rodriguez* + +* Move deprecated `ActiveRecord::TestCase` into the rails test + suite. The class is no longer public and is only used for internal + Rails tests. + + *Yves Senn* + +* Removed support for deprecated option `:restrict` for `:dependent` + in associations. + + *Neeraj Singh* + +* Removed support for deprecated `delete_sql` in associations. + + *Neeraj Singh* + +* Removed support for deprecated `insert_sql` in associations. + + *Neeraj Singh* + +* Removed support for deprecated `finder_sql` in associations. + + *Neeraj Singh* + +* Support array as root element in JSON fields. + + *Alexey Noskov & Francesco Rodriguez* + +* Removed support for deprecated `counter_sql` in associations. + + *Neeraj Singh* + +* Do not invoke callbacks when `delete_all` is called on collection. + + Method `delete_all` should not be invoking callbacks and this + feature was deprecated in Rails 4.0. This is being removed. + `delete_all` will continue to honor the `:dependent` option. However + if `:dependent` value is `:destroy` then the default deletion + strategy for that collection will be applied. + + User can also force a deletion strategy by passing parameter to + `delete_all`. For example you can do `@post.comments.delete_all(:nullify)` . + + *Neeraj Singh* + +* Calling default_scope without a proc will now raise `ArgumentError`. + + *Neeraj Singh* + +* Removed deprecated method `type_cast_code` from Column. + + *Neeraj Singh* + +* Removed deprecated options `delete_sql` and `insert_sql` from HABTM + association. + + Removed deprecated options `finder_sql` and `counter_sql` from + collection association. + + *Neeraj Singh* + +* Remove deprecated `ActiveRecord::Base#connection` method. + Make sure to access it via the class. + + *Yves Senn* + +* Remove deprecation warning for `auto_explain_threshold_in_seconds`. + + *Yves Senn* + +* Remove deprecated `:distinct` option from `Relation#count`. + + *Yves Senn* + +* Removed deprecated methods `partial_updates`, `partial_updates?` and + `partial_updates=`. + + *Neeraj Singh* + +* Removed deprecated method `scoped` + + *Neeraj Singh* + +* Removed deprecated method `default_scopes?` + + *Neeraj Singh* + +* Remove implicit join references that were deprecated in 4.0. + + Example: + + # before with implicit joins + Comment.where('posts.author_id' => 7) + + # after + Comment.references(:posts).where('posts.author_id' => 7) + + *Yves Senn* + +* Apply default scope when joining associations. For example: + + class Post < ActiveRecord::Base + default_scope -> { where published: true } + end + + class Comment + belongs_to :post + end + + When calling `Comment.joins(:post)`, we expect to receive only + comments on published posts, since that is the default scope for + posts. + + Before this change, the default scope from `Post` was not applied, + so we'd get comments on unpublished posts. + + *Jon Leighton* + +* Remove `activerecord-deprecated_finders` as a dependency + + *Łukasz Strzałkowski* + +* Remove Oracle / Sqlserver / Firebird database tasks that were deprecated in 4.0. + + *kennyj* + +* `find_each` now returns an `Enumerator` when called without a block, so that it + can be chained with other `Enumerable` methods. + + *Ben Woosley* + +* `ActiveRecord::Result.each` now returns an `Enumerator` when called without + a block, so that it can be chained with other `Enumerable` methods. + + *Ben Woosley* + +* Flatten merged join_values before building the joins. + + While joining_values special treatment is given to string values. + By flattening the array it ensures that string values are detected + as strings and not arrays. + + Fixes #10669. + + *Neeraj Singh and iwiznia* + +* Do not load all child records for inverse case. + + currently `post.comments.find(Comment.first.id)` would load all + comments for the given post to set the inverse association. + + This has a huge performance penalty. Because if post has 100k + records and all these 100k records would be loaded in memory + even though the comment id was supplied. + + Fix is to use in-memory records only if loaded? is true. Otherwise + load the records using full sql. + + Fixes #10509. + + *Neeraj Singh* + +* `inspect` on Active Record model classes does not initiate a + new connection. This means that calling `inspect`, when the + database is missing, will no longer raise an exception. + Fixes #10936. + + Example: + + Author.inspect # => "Author(no database connection)" + + *Yves Senn* + +* Handle single quotes in PostgreSQL default column values. + Fixes #10881. + + *Dylan Markow* + +* Log the sql that is actually sent to the database. + + If I have a query that produces sql + `WHERE "users"."name" = 'a b'` then in the log all the + whitespace is being squeezed. So the sql that is printed in the + log is `WHERE "users"."name" = 'a b'`. + + Do not squeeze whitespace out of sql queries. Fixes #10982. + + *Neeraj Singh* + +* Fixture setup no longer depends on `ActiveRecord::Base.configurations`. + This is relevant when `ENV["DATABASE_URL"]` is used in place of a `database.yml`. + + *Yves Senn* + +* Fix mysql2 adapter raises the correct exception when executing a query on a + closed connection. + + *Yves Senn* + +* Ambiguous reflections are on :through relationships are no longer supported. + For example, you need to change this: + + class Author < ActiveRecord::Base + has_many :posts + has_many :taggings, :through => :posts + end + + class Post < ActiveRecord::Base + has_one :tagging + has_many :taggings + end + + class Tagging < ActiveRecord::Base + end + + To this: + + class Author < ActiveRecord::Base + has_many :posts + has_many :taggings, :through => :posts, :source => :tagging + end + + class Post < ActiveRecord::Base + has_one :tagging + has_many :taggings + end + + class Tagging < ActiveRecord::Base + end + + *Aaron Patterson* + +* Remove column restrictions for `count`, let the database raise if the SQL is + invalid. The previous behavior was untested and surprising for the user. + Fixes #5554. + + Example: + + User.select("name, username").count + # Before => SELECT count(*) FROM users + # After => ActiveRecord::StatementInvalid + + # you can still use `count(:all)` to perform a query unrelated to the + # selected columns + User.select("name, username").count(:all) # => SELECT count(*) FROM users + + *Yves Senn* + +* Rails now automatically detects inverse associations. If you do not set the + `:inverse_of` option on the association, then Active Record will guess the + inverse association based on heuristics. + + Note that automatic inverse detection only works on `has_many`, `has_one`, + and `belongs_to` associations. Extra options on the associations will + also prevent the association's inverse from being found automatically. + + The automatic guessing of the inverse association uses a heuristic based + on the name of the class, so it may not work for all associations, + especially the ones with non-standard names. + + You can turn off the automatic detection of inverse associations by setting + the `:inverse_of` option to `false` like so: + + class Taggable < ActiveRecord::Base + belongs_to :tag, inverse_of: false + end + + *John Wang* + +* Fix `add_column` with `array` option when using PostgreSQL. Fixes #10432 + + *Adam Anderson* + +* Usage of `implicit_readonly` is being removed`. Please use `readonly` method + explicitly to mark records as `readonly. + Fixes #10615. + + Example: + + user = User.joins(:todos).select("users.*, todos.title as todos_title").readonly(true).first + user.todos_title = 'clean pet' + user.save! # will raise error + + *Yves Senn* + +* Fix the `:primary_key` option for `has_many` associations. + Fixes #10693. + + *Yves Senn* + +* Fix bug where tiny types are incorrectly coerced as boolean when the length is more than 1. + + Fixes #10620. + + *Aaron Patterson* + +* Also support extensions in PostgreSQL 9.1.
