-*   Configuration item `config.filter_parameters` could also filter out sensitive value of database column when call `#inspect`.
+*   Fix `transaction` reverting for migrations.
+
+    Before: Commands inside a `transaction` in a reverted migration ran uninverted.
+    Now: This change fixes that by reverting commands inside `transaction` block.
+
+    *fatkodima*, *David Verhasselt*
+
+*   Raise an error instead of scanning the filesystem root when `fixture_path` is blank.
+
+    *Gannon McGibbon*, *Max Albrecht*
+
+*   Allow `ActiveRecord::Base.configurations=` to be set with a symbolized hash.
+
+    *Gannon McGibbon*
+
+*   Don't update counter cache unless the record is actually saved.
+
+    Fixes #31493, #33113, #33117.
+
+    *Ryuta Kamizono*
+
+*   Deprecate `ActiveRecord::Result#to_hash` in favor of `ActiveRecord::Result#to_a`.
+
+    *Gannon McGibbon*, *Kevin Cheng*
+
+*   SQLite3 adapter supports expression indexes.
+
+    ```
+    create_table :users do |t|
+      t.string :email
+    end
+
+    add_index :users, 'lower(email)', name: 'index_users_on_email', unique: true
+    ```
+
+    *Gray Kemmey*
+
+*   Allow subclasses to redefine autosave callbacks for associated records.
+
+    Fixes #33305.
+
+    *Andrey Subbota*
+
+*   Bump minimum MySQL version to 5.5.8.
+
+    *Yasuo Honda*
+
+*   Use MySQL utf8mb4 character set by default.
+
+    `utf8mb4` character set with 4-Byte encoding supports supplementary characters including emoji.
+    The previous default 3-Byte encoding character set `utf8` is not enough to support them.
+
+    *Yasuo Honda*
+
+*   Fix duplicated record creation when using nested attributes with `create_with`.
+
+    *Darwin Wu*
+
+*   Configuration item `config.filter_parameters` could also filter out
+    sensitive values of database columns when call `#inspect`.
+    We also added `ActiveRecord::Base::filter_attributes`/`=` in order to
+    specify sensitive attributes to specific model.
 
     ```
     Rails.application.config.filter_parameters += [:credit_card_number]
-    Account.last.insepct # => #<Account id: 123, credit_card_number: [FILTERED] ...>
+    Account.last.inspect # => #<Account id: 123, name: "DHH", credit_card_number: [FILTERED] ...>
+    SecureAccount.filter_attributes += [:name]
+    SecureAccount.last.inspect # => #<SecureAccount id: 42, name: [FILTERED], credit_card_number: [FILTERED] ...>
     ```
