certbot 2.7.0

Certbot 2.7.0

on Python PyPI

Added

• Add certbot.util.LooseVersion class. See GH #9489.
• Add a new base class certbot.plugins.dns_common_lexicon.LexiconDNSAuthenticator to implement a DNS
  authenticator plugin backed by Lexicon to communicate with the provider DNS API. This approach relies
  heavily on conventions to reduce the implementation complexity of a new plugin.
• Add a new test base class certbot.plugins.dns_test_common_lexicon.BaseLexiconDNSAuthenticatorTest to
  help testing DNS plugins implemented on top of LexiconDNSAuthenticator.

Changed

• NamespaceConfig now tracks how its arguments were set via a dictionary, allowing us to remove a bunch
  of global state previously needed to inspect whether a user set an argument or not.
• Support for Python 3.7 was deprecated and will be removed in our next planned release.
• Added RENEWED_DOMAINS and FAILED_DOMAINS environment variables for consumption by post renewal hooks.
• Deprecates LexiconClient base class and build_lexicon_config function in
  certbot.plugins.dns_common_lexicon module in favor of LexiconDNSAuthenticator.
• Deprecates BaseLexiconAuthenticatorTest and BaseLexiconClientTest test base classes of
  certbot.plugins.dns_test_common_lexicon module in favor of BaseLexiconDNSAuthenticatorTest.

Fixed

• Do not call deprecated datetime.utcnow() and datetime.utcfromtimestamp()
• Filter zones in certbot-dns-google to avoid usage of private DNS zones to create records
