+*   Fix query attribute method on user-defined attribute to be aware of typecasted value.
+
+    For example, the following code no longer return false as casted non-empty string:
+
+    ```
+    class Post < ActiveRecord::Base
+      attribute :user_defined_text, :text
+    end
+
+    Post.new(user_defined_text: "false").user_defined_text? # => true
+    ```
+
+    *Yuji Kamijima*
+
+*   Quote empty ranges like other empty enumerables.
+
+    *Patrick Rebsch*
+
+*   Add `insert_all`/`insert_all!`/`upsert_all` methods to `ActiveRecord::Persistence`,
+    allowing bulk inserts akin to the bulk updates provided by `update_all` and
+    bulk deletes by `delete_all`.
+
+    Supports skipping or upserting duplicates through the `ON CONFLICT` syntax
+    for Postgres (9.5+) and Sqlite (3.24+) and `ON DUPLICATE KEY UPDATE` syntax
+    for MySQL.
+
+    *Bob Lail*
+
+*   Add `rails db:seed:replant` that truncates tables of each database
+    for current environment and loads the seeds.
+
+    *bogdanvlviv*, *DHH*
+
+*   Add `ActiveRecord::Base.connection.truncate` for SQLite3 adapter.
+
+    *bogdanvlviv*
+
+*   Deprecate mismatched collation comparison for uniqueness validator.
+
+    Uniqueness validator will no longer enforce case sensitive comparison in Rails 6.1.
+    To continue case sensitive comparison on the case insensitive column,
+    pass `case_sensitive: true` option explicitly to the uniqueness validator.
+
+    *Ryuta Kamizono*
+
+*   Add `reselect` method. This is a short-hand for `unscope(:select).select(fields)`.
+
+    Fixes #27340.
+
+    *Willian Gustavo Veiga*
+
 *   Add negative scopes for all enum values.
 
     Example:
-    
+
         class Post < ActiveRecord::Base
           enum status: %i[ drafted active trashed ]
         end
-  
+
         Post.not_drafted # => where.not(status: :drafted)
         Post.not_active  # => where.not(status: :active)
         Post.not_trashed # => where.not(status: :trashed)
-    
+
     *DHH*
 
 *   Fix different `count` calculation when using `size` with manual `select` with DISTINCT.
