mdbook test
. #1986
- Fixed regression in 0.4.26 that prevented the title bar from scrolling properly on smaller screens. #2039

- Pressing Escape will remove the
?highlight
argument from the URL. #1427 mdbook init --theme
will now place the theme in the root of the book directory instead of in thesrc
directory. #1432- A custom renderer that sets the
command
to a relative path now interprets the relative path relative to the book root. Previously it was inconsistent based on the platform (either relative to the current directory, or relative to the renderer output directory). Paths relative to the output directory are still supported with a deprecation warning. #1418 - The
theme
directory in the config is now interpreted as relative to the book root, instead of the current directory. #1405 - Handle UTF-8 BOM for chapter sources. #1285

local
font source for Source Code Pro, as the locally installed font may not render properly on FireFox on macOS. #1307

.nojekyll
file. #1310 - Fixed missing space before draft chapter titles. #1309
- The "show hidden lines" icon has changed from the "expand" icon to an "eye". #1281

- Fixed SUMMARY links that contained newlines. #1291
- Fixed SUMMARY links that contain
%20
spaces. #1293 - Fixed favicon so that if only the png or svg is overridden, the other is not
automatically included in the
<link>
tag. #1272

- Many dependencies have been updated or replaced.
This also removes the
--websocket-hostname
and--websocket-port
from theserve
command. #1211 - A new "404" page is now automatically rendered. This requires knowledge of
the base URL of your site to work properly. If you decide to use this as
your 404 page, you should set the
site-url
setting in the book configuration so mdbook can generate the links correctly. Alternatively you can disable the 404 page generation, or set up your own 404 handling in your web server. #1221 - The
debug
andoutput
features have been removed as they were unused. #1211 - If you are using customized themes, you may want to consider setting the
preferred-dark-theme
config setting, as it now defaults to "navy". #1199 - "Playpen" has been renamed to "playground". This is generally backwards
compatible for users, but
{{#playpen}}
will now display warnings. This may impact books that have modified the "playpen" elements in the theme. #1241 - If a renderer is not installed, it is now treated as an error. If you want
the old behavior of ignoring missing renderers, set the
optional
setting for that renderer. #1122 - If you have a custom favicon, you may need to look into adding an SVG version, otherwise the default SVG icon will be displayed. #1230
- Added a new
[rust]
configuration section tobook.toml
, which allows setting the default edition withedition = "2018"
. #1163 - Renderers can now be marked as
optional
, so that they will be ignored if the renderer is not installed. #1122 - Added
head.hbs
to allow adding content to the<head>
section in HTML. #1206 - Added "draft chapters". These are chapters listed without a link to indicate content yet to be written. #1153

to
SUMMARY.md
to signify different sections. #1171 - Added generation of a "404" page for handling missing pages and broken links. #1221
- Added configuration section for specifying URL redirects. #1237
- Added an SVG favicon that works with light and dark colors schemes. #1230
- Changed default Rust attribute of
allow(unused_variables)
toallow(unused)
. #1195 - Fonts are now served locally instead of from the Google Fonts CDN. The
copy-fonts
option was added to disable this if you want to supply your own fonts. #1188 - Switched the built-in webserver for the
serve
command to a new implementation. This results in some internal differences in how websockets are handled, which removes the separate websocket options. This should also make it easier to serve multiple books at once. #1211 - The default dark theme is now "navy". #1199
- "Playpen" has been renamed to "playground", matching the actual name of the service which was renamed many years ago. #1241
- Links with the
+
symbol should now work. #1208 - The
MDBOOK_BOOK
environment variable now correctly allows overriding the entire book configuration. #1207 - The sidebar can no longer be dragged outside of the window. #1229
- Hide the Rust Playground "play" button for
no_run
code samples. #1249 - Fixed the
--dest-dir
command-line option for theserve
andwatch
commands. #1228 - Hotkey handlers are now disabled in
text
input fields (for example, typingS
in a custom text input field). #1244
- Code spans in headers are no longer highlighted as code. #1162
- The sidebar will now scroll the activate page to the middle instead of the top. #1161
- Reverted change to reject build output within the
src
directory, and instead add a check that prevents infinite copies. #1181 #1026
MDBook::execute_build_process
is now publicly accessible in the API so that plugins can more easily initiate the build process. #1099
- Use a different color for Ayu theme's highlighting for Rust attributes (uses a bright color instead of the comment color). #1133
- Adjusted spacing of sidebar entries. #1137
- Slightly adjusted line-height of
<p>
,<ul>
, and<ol>
. #1136 - Handlebars updated to 3.0. #1130
- Fix an issue with sidebar scroll position on reload. #1108
mdbook serve
will retain the current scroll position when the page is reloaded. #1097- Fixed the page name if the book didn't have a title to not be prefixed with
-
. #1145 - HTML attributes
rel=next
andrel=previous
are now supported in "wide" mode (previously they were only set in narrow mode). #1150 - Prevent recursive copies when the destination directory is contained in the source directory. #1135
- Adjusted the menu bar animation to not immediately obscure the top content. #989
- Fix for comments in SUMMARY.md that appear between items. #1167

- Added a markdown renderer, which is off by default. This may be useful for debugging preprocessors. #1018
- Code samples may now include line numbers with the
output.html.playpen.line-numbers
configuration value. #1035 - The
watch
andserve
commands will now ignore files listed in.gitignore
. #1044 - Added automatic dark-theme detection based on the CSS
prefers-color-scheme
feature. This may be enabled by settingoutput.html.preferred-dark-theme
to your preferred dark theme. #1037 - Added
rustdoc_include
preprocessor. This makes it easier to include portions of an external Rust source file. The rest of the file is hidden, but the user may expand it to see the entire file, and will continue to work withmdbook test
. #1003 - Added Ctrl-Enter shortcut to the playpen editor to automatically run the sample. #1066
- Added
output.html.playpen.copyable
configuration option to disable the copy button. #1050 - Added ability to dynamically expand and fold sections within the sidebar.
See the
output.html.fold
configuration to enable this feature. #1027

💥 This release changes how links are handled in mdBook. Previously, relative links were interpreted relative to the book's root. In
0.2.0
+ links are relative to the page they are in, and use the.md
extension. This has several advantages, such as making links work in other markdown viewers like GitHub. You will likely have to change links in your book to accommodate this change. For example, a book with this layout:chapter_1/ section_1.md section_2.md SUMMARY.md
Previously a link in
section_1.md
tosection_2.md
would look like this:[section_2](chapter_1/section_2.html)
Now it must be changed to this:
[section_2](section_2.md)
-
💥
mdbook test --library-path
now accepts a comma-delimited list of arguments rather than taking all following arguments. This makes it easier to handle the trailing book directory argument without always needing to put--
before it. Multiple instances of the option continue to be accepted:mdbook test -L foo -L bar
. -
💥
mdbook serve
has some of its options renamed for clarity. Seemdbook help serve
for details. -
Embedded rust playpens now use the "stable" playground API. #754
