Release Notes

mkdocs/mkdocs (mkdocs)

v1.5.3

Compare Source

• Fix mkdocs serve sometimes locking up all browser tabs when navigating quickly (#​3390)

• Add many new supported languages for "search" plugin - update lunr-languages to 1.12.0 (#​3334)

• Bugfix (regression in 1.5.0): In "readthedocs" theme the styling of "breadcrumb navigation" was broken for nested pages (#​3383)

• Built-in themes now also support Chinese (Traditional, Taiwan) language (#​3370)

• Plugins can now set File.page to their own subclass of Page. There is also now a warning if File.page is set to anything other than a strict subclass of Page. (#​3367, #​3381)

  Note that just instantiating a Page sets the file automatically, so care needs to be taken not to create an unneeded Page.

Other small improvements; see commit log.
