Full Changelog: v3.0.0...v3.0.1

3.0.0

• BREAKING: Drop Python 3.7 support.
• BREAKING: Positional arguments are now positional only, and keyword arguments
  are keyword only.
• BREAKING: Passing source_address as a string argument (deprecated in 2.0) is now an error. source_address takes a (addr, port) tuple that is used as the local_addr param of asyncio.create_connection, allowing for binding to a specific IP. The local_hostname argument takes the value to be sent to the server with the EHLO/HELO message (which is what source_address was used for prior to 2.0).
• Change: don't use timeout value passed to connect everywhere, only for the initial connection (credit @wombatonfire)
• Change: removed unnecessary connection lost callback
• Change: revised handling for 'Future exception was never retrieved' warnings in protocol

v2.0.2

• Bugfix: don't send extra EHLO/HELO before QUIT (credit @ikrivosheev)
• Change: added SMTPConnectionResponseError for invalid response on connect only (credit @ikrivosheev)

2.0.1

Changes

• Bugfix: "tests" and "docs" in the sdist should be includes, not packages, so that they do not get put in site-packages.
