Linuxeden开源社区Release 1.4.14 includes deprecation paths for some API behaviors that had inadvertently been removed. It also includes a fix for the recently modified “empty IN” behaviors, as well as support for calling “.commit()” or “.rollback()” pre-emptively inside of transactional context managers. Finally, an adjustment to TypeDecorator will render a warning that user- defined TypeDecorator classes will want to “opt in” or “opt out” of caching by applying a flag cache_ok=[True|False] to these classes.
Thanks to our users and developers for their continued support and efforts on the project.
