This enables the admonitions support from pulldown-cmark. This includes
a config option in case it causes problems with existing books.
I would like to make this extensible in the future, though I'm not sure
what that would look like. There's also some concerns with how this will
affect translations like mdbook-i18n-helpers, which we may need to work
out in a different way.

This adds dynamic navigation of headers of the current page in the
sidebar. This is intended to help the user see what is on the current
page, and to be able to more easily navigate it. The "current" header is
tracked based on the scrolling behavior of the user, and is marked with
a small circle. This includes automatic folding to help keep it from
being too unwieldy on a page with a lot of nested headers.
This includes the `output.html.sidebar-header-nav` option to disable it.
I'm sure there are tweaks, fixes, and improvements that can be made. I'd
like to get this out now, and iterate on it over time to make
improvements.
This enables the hash-files setting by default. We have been running it
for a while, and it seems most of the issues have been resolved. This
should help with more reliably loading content like the toc contents.
This enables the smart-punctuation setting by default. The long term
plan is to continue to enable more markdown extensions by default across
semver breaking releases.
This adds the `optional` field to the preprocessor configuration to
mirror the same option for the `output` table. Missing preprocessors are
now an error unless the `optional` field is set. This should help with
inadvertently building a book when a missing preprocessor that you
expect to be installed.
This replaces the `{{#previous}}` and `{{#next}}` handelbars helpers
with simple objects that contain the previous and next values. These
helpers have been a bit fussy to work with and have caused issues in the
past. This drops a large amount of somewhat fragile code with something
that is a bit simpler.
Additionally, this switches the previous/next arrows to use an `{{#if}}`
instead CSS trickery which may help with upcoming changes to
font-awesome.
This removes the deprecated `output.html.copy-fonts` option. This was
deprecated in https://github.com/rust-lang/mdBook/pull/1987. The
behavior now is that the default fonts are copied over unless there is a
custom `theme/fonts/fonts.css` file.
This adds the ability to redirect URLs with `#` fragments. This is
useful when section headers get renamed or moved to other pages.
This works both for deleted pages and existing pages.
The implementation requires the use of JavaScript in order to manipulate
the location. (Ideally this would be handled on the server side.)
This also makes it so that deleted page redirects preserve the fragment
ID. Previously if you had a deleted page redirect, and the user went to
something like `page.html#foo`, it would redirect to `bar.html` without
the fragment. I think preserving the fragment is probably a better
behavior. If the new page doesn't have the fragment ID, then no harm is
really done. This is technically an open redirect, but I don't think
that there is too much danger with preserving a fragment ID?
This config setting provides the ability to disable search indexing on a
per-chapter (or sub-path) basis.
This is structured to possibly add additional settings, such as perhaps
a score multiplier or other settings.
Nim is a systems programming language (included in the highlight.js
`system` group), and we're quite happily using `mdBook` in several of
our documentation projects starting with our [style
guide](https://status-im.github.io/nim-style-guide/).
While we can maintain our own highlight.js, including `Nim` in the
default distribution would allow us to promote more mdBook usage in the
Nim community at the cost of a ~2kb increase in the `highlight.js` size.
