[orm] [declarative] [bug] [regression] Fixed regression where recent changes to support Python dataclasses had the
inadvertent effect that an ORM mapped class could not successfully override
the __new__() method.
[engine] [bug] [regression] Fixed critical regression caused by the change in #5497 where the
connection pool "init" phase no longer occurred within mutexed isolation,
allowing other threads to proceed with the dialect uninitialized, which
could then impact the compilation of SQL statements.
[orm] [usecase] Altered some of the behavior repaired in #6232 where the
immediateload loader strategy no longer goes into recursive loops; the
modification is that an eager load (joinedload, selectinload, or
subqueryload) from A->bs->B which then states immediateload for a
simple manytoone B->a->A that's in the identity map will populate the B->A,
so that this attribute is back-populated when the collection of A/A.bs are
loaded. This allows the objects to be functional when detached.
[orm] [bug] Fixed bug in new _orm.with_loader_criteria() feature where using a
mixin class with _orm.declared_attr() on an attribute that were
accessed inside the custom lambda would emit a warning regarding using an
unmapped declared attr, when the lambda callable were first initialized.
This warning is now prevented using special instrumentation for this
lambda initialization step.
[orm] [bug] [regression] Fixed additional regression caused by the "eagerloaders on refresh" feature
added in #1763 where the refresh operation historically would set
populate_existing, which given the new feature now overwrites pending
