Deprecated transaction.is_managed().
...
It's synchronized with the autocommit flag.

Deprecated transaction.commit/rollback_unless_managed.
...
Since "unless managed" now means "if database-level autocommit",
committing or rolling back doesn't have any effect.
Restored transactional integrity in a few places that relied on
automatically-started transactions with a transitory API.

Made transaction.managed a no-op and deprecated it.
...
enter_transaction_management() was nearly always followed by managed().
In three places it wasn't, but they will all be refactored eventually.
The "forced" keyword argument avoids introducing behavior changes until
then.
This is mostly backwards-compatible, except, of course, for managed
itself. There's a minor difference in _enter_transaction_management:
the top self.transaction_state now contains the new 'managed' state
rather than the previous one. Django doesn't access
self.transaction_state in _enter_transaction_management.

Send post_delete signals immediately
...
In a normal relational construct, if you're listening for an event
that signals a child was deleted, you dont expect that the parent
was deleted already.
This change ensures that post_delete signals are fired immediately
after objects are deleted in the graph.

Fixed #18676 -- Allow fast-path deletion of objects
...
Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.
Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing
the patch.
