Release notes

Sourced from mkdocs's releases.

1.2.2

MkDocs 1.2.2 is a bugfix release for MkDocs 1.2 -- make sure you've seen the "major" release notes as well.

• Bugfix (regression in 1.2): Fix serving files/paths with Unicode characters (#2464)

• Bugfix (regression in 1.2): Revert livereload file watching to use polling observer (#2477)

  This had to be done to reasonably support usages that span virtual filesystems such as non-native Docker and network mounts.

  This goes back to the polling approach, very similar to that was always used prior, meaning most of the same downsides with latency and CPU usage.

• Revert from 1.2: Remove the requirement of a site_url config and the restriction on use_directory_urls (#2490)

• Bugfix (regression in 1.2): Don't require trailing slash in the URL when serving a directory index in mkdocs serve server (#2507)

  Instead of showing a 404 error, detect if it's a directory and redirect to a path with a trailing slash added, like before.

• Bugfix: Fix gh_deploy with config-file in the current directory (#2481)

• Bugfix: Fix reversed breadcrumbs in "readthedocs" theme (#2179)

• Allow "mkdocs.yaml" as the file name when '--config' is not passed (#2478)

• Stop treating ";" as a special character in URLs: urlparse -> urlsplit (#2502)

• Improve build performance for sites with many pages (partly already done in 1.2) (#2407)
