SQLAlchemy 1.2.10 已发布，这是一个小版本，引入了一些针对 Core 和 ORM 的修复：
- [orm] [bug] Fixed bug in
Bundleconstruct where placing two columns of the same name would be de-duplicated, when the
Bundlewere used as part of the rendered SQL, such as in the ORDER BY or GROUP BY of the statement.
- [orm] [bug] Fixed regression in 1.2.9 due to #4287 where using a
Loadoption in conjunction with a string wildcard would result in a TypeError.
- [sql] [bug] Fixed bug where a
Sequencewould be dropped explicitly before any
Tablethat refers to it, which breaks in the case when the sequence is also involved in a server-side default for that table, when using
MetaData.drop_all(). The step which processes sequences to be dropped via non server-side column default functions is now invoked after the table itself is dropped.
