v3.0.2

• Bugfix: Type of "send" is partially unknown with pyright
• Bugfix: Fix asyncio deadlock trying to reconnect after error (thanks @Voldemat)
• Change: Switched from Poetry to build/hatch/twine for packaging.

Full Changelog: v3.0.1...v3.0.2

v3.0.1

• Bugfix: 'Future exception was never retrieved' warning in SMTPProtocol after successful connection close and garbage collection.
• Cleanup: Updated FlowControlMixin logic from stdlib

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.

v2.0.0

• BREAKING: Drop Python 3.5 and 3.6 support.

• BREAKING: On connect, if the server supports STARTTLS, automatically try
  to upgrade the connection. STARTTLS after connect can be turned on or off
  explicitly by passing start_tls=True or start_tls=False respectively.

• BREAKING: Remove deprecated loop keyword argument for the SMTP class.

• Change: The source_address argument now takes a (addr, port) tuple that is
  passed as the local_addr param to asyncio.create_connection, allowing
  for binding to a specific IP. The new local_hostname argument that takes
  the value to be sent to the server with the EHLO/HELO message. This behaviour
  more closely matches smtplib.

  In order to not break existing usage, passing a string instead of a tuple to
  source_address will give a DeprecationWarning, and use the value as it if
  had been passed for local_hostname.

  Thanks @rafaelrds and @davidmcnabnz for raising and contributing work on this
  issue.

• Bugfix: the mail_options and rcpt_options arguments to the send
  coroutine no longer cause errors

• Cleanup: Refactored SMTP parent classes to remove complex inheritance
  structure.

• Cleanup: Switched to asyncio.run for sync client methods.

• Cleanup: Don't use private email.message.Message policy attribute (instead,
  set an appropriate policy based on message class)

v1.1.7

What's Changed

• Security: Fix a possible injection vulnerability (a variant of
  https://consensys.net/diligence/vulnerabilities/python-smtplib-multiple-crlf-injection/)

  Note that in order to exploit this vulnerability in aiosmtplib, the attacker would need
  control of the hostname or source_address parameters. Thanks Sam Sanoop @ Snyk
  for bringing this to my attention.

• Bugfix: include CHANGLOG in sdist release

• Type hints: fix type hints for async context exit (credit @JelleZijlstra)
  Full Changelog: v1.1.6...v1.1.7

v1.1.5

• Bugfix: allow UTF-8 chars in usernames and password strings
• Feature: allow bytes type args for login usernames and passwords
