includes adjustment to setup.py to recognize __version__ correctly
Fixed bug where a :class:`.Sequence` would be dropped explicitly before any :class:`.Table` that refers to it, which breaks in the case when the sequence is also involved in a server-side default for that table, when using :meth:`.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. Change-Id: I185f2cc76d2011ad4dd3ba9bde5d8aef0ec335ae Fixes: #4300 (cherry picked from commit 532566ba1f28ff8a6afa6eacc10c59eb918501f6)
Fixed connection pool issue whereby if a disconnection error were raised during the connection pool's "reset on return" sequence in conjunction with an explicit transaction opened against the enclosing :class:`.Connection` object (such as from calling :meth:`.Session.close` without a rollback or commit, or calling :meth:`.Connection.close` without first closing a transaction declared with :meth:`.Connection.begin`), a double-checkin would result, which could then lead towards concurrent checkouts of the same connection. The double-checkin condition is now prevented overall by an assertion, as well as the specific double-checkin scenario has been fixed.

Fixed a reference leak issue where the values of the parameter dictionary used in a statement execution would remain referenced by the "compiled cache", as a result of storing the key view used by Python 3 dictionary keys().

Fixed 1.2 regression caused by :ticket:`4060` where the query used to reflect SQL Server cross-schema foreign keys was limiting the criteria incorrectly. Additionally, added some rework of the inter-schema reflection tests so that MySQL, MSSQL can be included, breaking out some of the Postgresql-specific behaviors into separate requirements. Fixes: #4234 Change-Id: I20c8e70707075f1767b79127c2c27d4b313c6515 (cherry picked from commit 9d5e117f6fcc38d8773bc943c615888dc8a3a819)
Fixed bug in connection pool where a connection could be present in the pool without all of its "connect" event handlers called, if a previous "connect" handler threw an exception; note that the dialects themselves have connect handlers that emit SQL, such as those which set transaction isolation, which can fail if the database is in a non-available state, but still allows a connection. The connection is now invalidated first if any of the connect handlers fail. Change-Id: I61d6f4827a98ab8455f1c3e1c55d046eeccec09a Fixes: #4225 (cherry picked from commit c5437296713288cbfcd323032ca48a75a97e10e5)
Fixed regression caused in 1.2.3 due to fix from :ticket:`4181` where the changes to the event system involving :class:`.Engine` and :class:`.OptionEngine` did not accommodate for event removals, which would raise an ``AttributeError`` when invoked at the class level. Change-Id: I1c9083829d74dd710716d28b0eaca4fa15e86313 Fixes: #4190
The :class:`.URL` object now allows query keys to be specified multiple times where their values will be joined into a list. This is to support the plugins feature documented at :class:`.CreateEnginePlugin` which documents that "plugin" can be passed multiple times. Additionally, the plugin names can be passed to :func:`.create_engine` outside of the URL using the new :paramref:`.create_engine.plugins` parameter.
