• Officially support Python 3.11 (#3020)

  Note: Simply upgrading to Python 3.11 can cut off 10-15% of your site's build time.

• Support multiple instances of the same plugin (#3027)

  If a plugin is specified multiple times in the list under the plugins: config, that will create 2 (or more) instances of the plugin with their own config each.

  Previously this case was unforeseen and, as such, bugged.

  Now even though this works, by default a warning will appear from MkDocs anyway, unless the plugin adds a class variable supports_multiple_instances = True.

• Bugfix (regression in 1.4.1): Don't error when a plugin puts a plain string into warnings (#3016)

• Bugfix: Relative links will always render with a trailing slash (#3022)

  Previously under use_directory_urls, links from a sub-page to the main index page rendered as e.g. <a href="../.."> even though in all other cases the links look like <a href="../../">. This caused unwanted behavior on some combinations of Web browsers and servers. Now this special-case bug was removed.

• Built-in "mkdocs" theme now also supports Norwegian language (#3024)

• Plugin-related warnings look more readable (#3016)
