• Fixed .count() when a join happens (#109) (#118)

• Fixed 'unique_together' for foreign keys (#114)
• Fixed Field.to_db_value method to handle Enum (#113) (#115) (#116)

Added ability to create tables with "unique_together" meta options (#112)

Fixed concurrency isolation when attempting to do multiple concurrent operations on a single connection.

• Fixed several convenince issues with foreign relations:
  • FIXED: .all() actually returns the _query property as was documented.
  • New models with FK don't automatically fail to resolve any data. They can now be evaluated lazily.

• Some DB's don't support OFFSET without Limit, added caps to signal workaround, which is to automatically add limit of 1000000
• Pylint plugin to know about default related_name for ForeignKey fields.
• Simplified capabilities to be static, and defined at class level.

• Added basic DB driver Capabilities.

  Test runner now has the ability to skip tests conditionally, based on the DB driver Capabilities:

  @requireCapability(dialect='sqlite')
  async def test_run_sqlite_only(self):
      ...
  

• Added per-field indexes.

  When setting index=True on a field, Tortoise will now generate an index for it.

  NOTE:

  Due to MySQL limitation of not supporting conditional index creation,
  if `safe=True` (the default) is set, it won't create the index and emit a warning about it.
  
  We plan to work around this limitation in a future release.
