Seems that way. Careful testing will as always confirm the methodology and implementation.

Thank you!

So, the following is all true?


    Recap'ing the solution (Jason's and yours combined):

    1- On `after_flush`, call `history_meta.create_version()` for each
    object that is changing so its `XYZHistory` instance is created and
    can be stored within `session.info <http://session.info/>`.
    2. On `before_commit`, do `session.add()` for each history instance
    (`XYZHistory`) in `session.info <http://session.info/>` and increase
    `version` of each object associated to each history instance.
    3. On `after_transaction_end`, if `transaction.parent` is `None`,
    clean up `session.info <http://session.info/>`.

    True?

    And, even if there was a `session rollback` and/or `soft rollback`,
    the `session.info <http://session.info/>` would have been cleaned up
    by step 3. True?
