Release Notes

ruby/rdoc (rdoc)

v8.0.0

Compare Source

RDoc 8.0.0 is the biggest RDoc release in years. It brings together the work we have been doing to modernize Ruby's documentation experience: a Prism-based parser, RBS signatures in generated documentation, .rbs files as documentation input, a live preview server, theme polish, and many long-standing bug fixes.

For users, the biggest visible change is that RDoc can now show type information next to method documentation. RBS signatures are rendered in both HTML and ri, and the Aliki theme now presents method entries as signature cards. This should make generated documentation more useful for both human readers and tools that consume Ruby documentation.

For documentation authors, RDoc 8.0.0 adds rdoc --server and rake rdoc:server, giving you a local preview server with live reload. This release also includes many fixes around Markdown, cross-references, page links, C source handling, server mode, and generated HTML structure. The goal is to make writing and checking documentation less tedious.

Internally, RDoc has migrated to the Prism-based parser and removed the old Ripper-based parser. This saves RDoc from re-implementing new Ruby syntax support manually going forward. The release also includes a refreshed coverage report, a new user-facing configuration reference, more Aliki polish, and finally, an RDoc logo.

There are breaking changes in this release, so please read the details below before upgrading. But overall, RDoc 8.0.0 is a big step toward making Ruby's documentation tooling feel actively maintained again.
