 ### Database
 
+- Schema dialects now support `CURRENT_DATE` and `CURRENT_TIME` as column
+  defaults on `date` and `time` columns. Each dialect emits its own syntax,
+  for example `DEFAULT (CURRENT_DATE)` on MySQL and
+  `DEFAULT CONVERT(DATE, GETDATE())` on SQL Server. Previously these values
+  were quoted as string literals.
 - `Cake\Database\Expression\JsonPathExpression` was added. This expression
   object provides a fluent interface for defining JSON path expressions.
