:version: 1.5.6
- :include_notes_from: unreleased
+ :released: March 5, 2021
+
+ .. change::
+ :tags: bug, mssql, operations
+ :tickets: 812
+
+ Fixed bug where the "existing_type" parameter, which the MSSQL dialect
+ requires in order to change the nullability of a column in the absence of
+ also changing the column type, would cause an ALTER COLUMN operation to
+ incorrectly render a second ALTER statement without the nullability if a
+ new type were also present, as the MSSQL-specific contract did not
+ anticipate all three of "nullability", "type_" and "existing_type" being
+ sent at the same time.
+
+
+ .. change::
+ :tags: template
+ :ticket: 805
+
+ Add async template to Alembic to bootstrap environments that use
+ async DBAPI. Updated the cookbook to include a migration guide
+ on how to adapt an existing enviroment for use with DBAPI drivers.
