• Improved sidebar and breadcrumbs navigation (@panglesd, @gpetiot). The documentation pages and the libraries of the entire package are shown on the left sidebar.
• Added support for images, videos, audio and other assets. The syntax is {image!/reference/to/asset} or {image:URL} for images. The syntax for {video...} and {audio...} is the same. (@panglesd, @EmileTrotignon, #1170, #1171, #1184, #1185)
• Search using Sherlodoc (@panglesd, @EmileTrotignon, @Julow). A new search bar that supports full-text and type-based search.

Added

  • Hierarchy: odoc compile now outputs .odoc in the directory tree specified with --output-dir=DIR and the parent identifier must be specified with --parent-id=PARENT. The option --source-parent-file is removed.
  • Source code: Implementations are compiled with compile-impl instead of with compile. The options --cmt=.. and --source-name=.. are removed. Source code pages are generated with html-generate-source.
  • Assets: The commands compile-asset, html-generate-asset are added. The option html-generate --asset is removed.
