-*   Add `unsigned` support for numeric data types in MySQL.
+*   MySQL: support `unsigned` numeric data types.
 
     Example:
 
         create_table :foos do |t|
-          t.integer :unsigned_integer, unsigned: true
-          t.bigint  :unsigned_bigint,  unsigned: true
-          t.float   :unsigned_float,   unsigned: true
-          t.decimal :unsigned_decimal, unsigned: true, precision: 10, scale: 2
+          t.unsigned_integer :quantity
+          t.unsigned_bigint  :total
+          t.unsigned_float   :percentage
+          t.unsigned_decimal :price, precision: 10, scale: 2
         end
 
-    In the case of using `unsigned` as the type:
+    The `unsigned: true` option may be used for the primary key:
 
-        create_table :foos do |t|
-          t.unsigned_integer :unsigned_integer
-          t.unsigned_bigint  :unsigned_bigint
-          t.unsigned_float   :unsigned_float
-          t.unsigned_decimal :unsigned_decimal, precision: 10, scale: 2
+        create_table :foos, id: :bigint, unsigned: true do |t|
+          …
+        end

+*   Add `#views` and `#view_exists?` methods on connection adapters.

+
+*   Correctly dump composite primary key.
+
+    Example:
+
+        create_table :barcodes, primary_key: ["region", "code"] do |t|
+          t.string :region
+          t.integer :code
         end
