1.2.18:
orm

[orm] [bug] Fixed a regression in 1.2 where a wildcard/load_only loader option \ 
would not work correctly against a loader path where of_type() were used to \ 
limit to a particular subclass. The fix only works for of_type() of a simple \ 
subclass so far, not a with_polymorphic entity which will be addressed in a \ 
separate issue; it is unlikely this latter case was working previously.

[orm] [bug] Fixed fairly simple but critical issue where the \ 
SessionEvents.pending_to_persistent() event would be invoked for objects not \ 
just when they move from pending to persistent, but when they were also already \ 
persistent and just being updated, thus causing the event to be invoked for all \ 
objects on every update.

sql
[sql] [bug] Fixed issue where the JSON type had a read-only \ 
JSON.should_evaluate_none attribute, which would cause failures when making use \ 
of the TypeEngine.evaluates_none() method in conjunction with this type. Pull \ 
request courtesy Sanjana S.

mysql
[mysql] [bug] Fixed a second regression caused by 4344 (the first was 4361), \ 
which works around MySQL issue 88718, where the lower casing function used was \ 
not correct for Python 2 with OSX/Windows casing conventions, which would then \ 
raise TypeError. Full coverage has been added to this logic so that every \ 
codepath is exercised in a mock style for all three casing conventions on all \ 
versions of Python. MySQL 8.0 has meanwhile fixed issue 88718 so the workaround \ 
is only applies to a particular span of MySQL 8.0 versions.

sqlite
[sqlite] [bug] Fixed bug in SQLite DDL where using an expression as a server \ 
side default required that it be contained within parenthesis to be accepted by \ 
the sqlite parser. Pull request courtesy Bartlomiej Biernacki.

mssql
[mssql] [bug] Fixed bug where the SQL Server “IDENTITY_INSERT” logic that \ 
allows an INSERT to proceed with an explicit value on an IDENTITY column was not \ 
detecting the case where Insert.values() were used with a dictionary that \ 
contained a Column as key and a SQL expression as a value
