certbot/certbot v1.6.0

Certbot 1.6.0

on GitHub

Added

• Certbot snaps are now available for the arm64 and armhf architectures.
• Add minimal code to run Nginx plugin on NetBSD.
• Make Certbot snap find externally snapped plugins
• Function certbot.compat.filesystem.umask is a drop-in replacement for os.umask
  implementing umask for both UNIX and Windows systems.
• Support for alternative certificate chains in the acme module.
• Added --preferred-chain <issuer CN>. If a CA offers multiple certificate chains,
  it may be used to indicate to Certbot which chain should be preferred.
  • e.g. --preferred-chain "DST Root CA X3"

Changed

• Allow session tickets to be disabled in Apache when mod_ssl is statically linked.
• Generalize UI warning message on renewal rate limits
• Certbot behaves similarly on Windows to on UNIX systems regarding umask, and
  the umask 022 is applied by default: all files/directories are not writable by anyone
  other than the user running Certbot and the system/admin users.
• Read acmev1 Let's Encrypt server URL from renewal config as acmev2 URL to prepare
  for impending acmev1 deprecation.

Fixed

• Cloudflare API Tokens may now be restricted to individual zones.
• Don't use StrictVersion, but LooseVersion to check version requirements with setuptools,
  to fix some packaging issues with libraries respecting PEP404 for version string,
  with doesn't match StrictVersion requirements.
• Certbot output doesn't refer to SSL Labs due to confusing scoring behavior.
• Fix paths when calling to programs outside of the Certbot Snap, fixing the apache and nginx
  plugins on, e.g., CentOS 7.
