 383
 384 ### Changed
 385 - The "show hidden lines" icon has changed from the "expand" icon to an "eye".
 386   [#1281](https://github.com/rust-lang/mdBook/pull/1281)
 387 - Updated highlight.js. This adds several languages: c, c-like (effectively
 388   cpp), csharp (replaces cs), kotlin, less, lua, php-template, plaintext,
 389   python-repl, r, scss, typescript.
 390   [#1277](https://github.com/rust-lang/mdBook/pull/1277)

 415 [99ecd4f...d4df7e7](https://github.com/rust-lang/mdBook/compare/99ecd4f...d4df7e7)
 416
 417 ### Breaking Changes
 418 - Several of the changes in the release have altered the public API of the
 419   mdbook library.
 420 - Many dependencies have been updated or replaced.
 421   This also removes the `--websocket-hostname` and `--websocket-port` from
 422   the `serve` command.
 423   [#1211](https://github.com/rust-lang/mdBook/pull/1211)
 424 - A new "404" page is now automatically rendered. This requires knowledge of
 425   the base URL of your site to work properly. If you decide to use this as
 426   your 404 page, you should set the `site-url` setting in the book
 427   configuration so mdbook can generate the links correctly. Alternatively you
 428   can disable the 404 page generation, or set up your own 404 handling in your
 429   web server.
 430   [#1221](https://github.com/rust-lang/mdBook/pull/1221)
 431 - The `debug` and `output` features have been removed as they were unused.
 432   [#1211](https://github.com/rust-lang/mdBook/pull/1211)
 433 - If you are using customized themes, you may want to consider setting the
 434   `preferred-dark-theme` config setting, as it now defaults to "navy".
 435   [#1199](https://github.com/rust-lang/mdBook/pull/1199)
 436 - "Playpen" has been renamed to "playground". This is generally backwards
 437   compatible for users, but `{{#playpen}}` will now display warnings. This may
 438   impact books that have modified the "playpen" elements in the theme.
 439   [#1241](https://github.com/rust-lang/mdBook/pull/1241)
 440 - If a renderer is not installed, it is now treated as an error. If you want
 441   the old behavior of ignoring missing renderers, set the `optional` setting
 442   for that renderer.
 443   [#1122](https://github.com/rust-lang/mdBook/pull/1122)
 444 - If you have a custom favicon, you may need to look into adding an SVG
 445   version, otherwise the default SVG icon will be displayed.
 446   [#1230](https://github.com/rust-lang/mdBook/pull/1230)
 447
 448 ### Added
 449 - Added a new `[rust]` configuration section to `book.toml`, which allows
 450   setting the default edition with `edition = "2018"`.
 451   [#1163](https://github.com/rust-lang/mdBook/pull/1163)
 452 - Renderers can now be marked as `optional`, so that they will be ignored if
 453   the renderer is not installed.
 454   [#1122](https://github.com/rust-lang/mdBook/pull/1122)
 455 - Added `head.hbs` to allow adding content to the `<head>` section in HTML.
 456   [#1206](https://github.com/rust-lang/mdBook/pull/1206)
 457 - Added "draft chapters". These are chapters listed without a link to indicate
 458   content yet to be written.
 459   [#1153](https://github.com/rust-lang/mdBook/pull/1153)
 460 - Added "parts" to split a book into different sections. Headers can be added
 461   to `SUMMARY.md` to signify different sections.
 462   [#1171](https://github.com/rust-lang/mdBook/pull/1171)
 463 - Added generation of a "404" page for handling missing pages and broken links.
 464   [#1221](https://github.com/rust-lang/mdBook/pull/1221)
 465 - Added configuration section for specifying URL redirects.
 466   [#1237](https://github.com/rust-lang/mdBook/pull/1237)
 467 - Added an SVG favicon that works with light and dark colors schemes.
 468   [#1230](https://github.com/rust-lang/mdBook/pull/1230)
 469
 470 ### Changed
 471 - Changed default Rust attribute of `allow(unused_variables)` to `allow(unused)`.
 472   [#1195](https://github.com/rust-lang/mdBook/pull/1195)
 473 - Fonts are now served locally instead of from the Google Fonts CDN. The
 474   `copy-fonts` option was added to disable this if you want to supply your own
 475   fonts.
 476   [#1188](https://github.com/rust-lang/mdBook/pull/1188)
 477 - Switched the built-in webserver for the `serve` command to a new
 478   implementation. This results in some internal differences in how websockets
 479   are handled, which removes the separate websocket options. This should also
 480   make it easier to serve multiple books at once.
 481   [#1211](https://github.com/rust-lang/mdBook/pull/1211)
 482 - The default dark theme is now "navy".
 483   [#1199](https://github.com/rust-lang/mdBook/pull/1199)
 484 - "Playpen" has been renamed to "playground", matching the actual name of the
 485   service which was renamed many years ago.
 486   [#1241](https://github.com/rust-lang/mdBook/pull/1241)
 487
 488 ### Fixed
 489 - Links with the `+` symbol should now work.
 490   [#1208](https://github.com/rust-lang/mdBook/pull/1208)
 491 - The `MDBOOK_BOOK` environment variable now correctly allows overriding the
 492   entire book configuration.
 493   [#1207](https://github.com/rust-lang/mdBook/pull/1207)
 494 - The sidebar can no longer be dragged outside of the window.
 495   [#1229](https://github.com/rust-lang/mdBook/pull/1229)
 496 - Hide the Rust Playground "play" button for `no_run` code samples.
 497   [#1249](https://github.com/rust-lang/mdBook/pull/1249)
 498 - Fixed the `--dest-dir` command-line option for the `serve` and `watch`
 499   commands.
 500   [#1228](https://github.com/rust-lang/mdBook/pull/1228)
 501 - Hotkey handlers are now disabled in `text` input fields (for example, typing
 502   `S` in a custom text input field).

 509 - Code spans in headers are no longer highlighted as code.
 510   [#1162](https://github.com/rust-lang/mdBook/pull/1162)
 511 - The sidebar will now scroll the activate page to the middle instead of the top.
 512   [#1161](https://github.com/rust-lang/mdBook/pull/1161)
 513 - Reverted change to reject build output within the `src` directory, and
 514   instead add a check that prevents infinite copies.
 515   [#1181](https://github.com/rust-lang/mdBook/pull/1181)
 516   [#1026](https://github.com/rust-lang/mdBook/pull/1026)

 526
 527 ### Added
 528 - `MDBook::execute_build_process` is now publicly accessible in the API so
 529   that plugins can more easily initiate the build process.
 530   [#1099](https://github.com/rust-lang/mdBook/pull/1099)
 531
 532 ### Changed
 533 - Use a different color for Ayu theme's highlighting for Rust attributes (uses
 534   a bright color instead of the comment color).

 536 - Adjusted spacing of sidebar entries.
 537   [#1137](https://github.com/rust-lang/mdBook/pull/1137)

 543 ### Fixed
 544 - Fix an issue with sidebar scroll position on reload.
 545   [#1108](https://github.com/rust-lang/mdBook/pull/1108)
 546 - `mdbook serve` will retain the current scroll position when the page is reloaded.
 547   [#1097](https://github.com/rust-lang/mdBook/pull/1097)
 548 - Fixed the page name if the book didn't have a title to not be prefixed with ` - `.
 549   [#1145](https://github.com/rust-lang/mdBook/pull/1145)
 550 - HTML attributes `rel=next` and `rel=previous` are now supported in "wide"

 599
 600 ### Added
 601 - Added a markdown renderer, which is off by default. This may be useful for
 602   debugging preprocessors.
 603   [#1018](https://github.com/rust-lang/mdBook/pull/1018)
 604 - Code samples may now include line numbers with the
 605   `output.html.playpen.line-numbers` configuration value.
 606   [#1035](https://github.com/rust-lang/mdBook/pull/1035)
 607 - The `watch` and `serve` commands will now ignore files listed in
 608   `.gitignore`.
 609   [#1044](https://github.com/rust-lang/mdBook/pull/1044)
 610 - Added automatic dark-theme detection based on the CSS `prefers-color-scheme`
 611   feature. This may be enabled by setting `output.html.preferred-dark-theme`
 612   to your preferred dark theme.
 613   [#1037](https://github.com/rust-lang/mdBook/pull/1037)
 614 - Added `rustdoc_include` preprocessor. This makes it easier to include
 615   portions of an external Rust source file. The rest of the file is hidden,
 616   but the user may expand it to see the entire file, and will continue to work
 617   with `mdbook test`.
 618   [#1003](https://github.com/rust-lang/mdBook/pull/1003)
 619 - Added Ctrl-Enter shortcut to the playpen editor to automatically run the
 620   sample.

 628
 629 ### Changed
 630 - Use standard `scrollbar-color` CSS along with webkit extension
 631   [#816](https://github.com/rust-lang/mdBook/pull/816)
 632 - The renderer build directory is no longer deleted before the renderer is
 633   run. This allows a backend to cache results between runs.
 634   [#985](https://github.com/rust-lang/mdBook/pull/985)
 635 - Next/prev links now highlight on hover to indicate it is clickable.
 636   [#994](https://github.com/rust-lang/mdBook/pull/994)
 637 - Increase padding of table headers.
 638   [#824](https://github.com/rust-lang/mdBook/pull/824)

 640   [#1033](https://github.com/rust-lang/mdBook/pull/1033)
 641 - Updated highlight.js for syntax highlighting updates (primarily to add
 642   async/await to Rust highlighting).
 643   [#1041](https://github.com/rust-lang/mdBook/pull/1041)
 644 - Raised minimum supported rust version to 1.35.
 645   [#1003](https://github.com/rust-lang/mdBook/pull/1003)
 646 - Hidden code lines are no longer dynamically removed via JavaScript, but
 647   instead managed with CSS.
 648   [#846](https://github.com/rust-lang/mdBook/pull/846)
 649   [#1065](https://github.com/rust-lang/mdBook/pull/1065)
 650 - Changed the default font set for the ACE editor, giving preference to
 651   "Source Code Pro".
 652   [#1062](https://github.com/rust-lang/mdBook/pull/1062)
 653 - Windows 32-bit releases are no longer published.
 654   [#1071](https://github.com/rust-lang/mdBook/pull/1071)
 655
 656 ### Fixed
 657 - Fixed sidebar auto-scrolling.
 658   [#1052](https://github.com/rust-lang/mdBook/pull/1052)
 659 - Fixed error message when running `clean` multiple times.
 660   [#1055](https://github.com/rust-lang/mdBook/pull/1055)

 662   [#1005](https://github.com/rust-lang/mdBook/pull/1005)
 663 - Stop using `inline-block` for `inline code`, fixing selection highlighting
 664   and some rendering issues.
 665   [#1058](https://github.com/rust-lang/mdBook/pull/1058)
 666 - Fix header auto-hide on browsers with momentum scrolling that allows
 667   negative `scrollTop`.

 675   [#851](https://github.com/rust-lang/mdBook/pull/851)
 676 - Added `language` configuration value to set the language of the book, which
 677   will affect things like the `<html lang="en">` tag.

 721 - Highlight.js has been updated. This fixes some TOML highlighting, and adds
 722   Julia support.
 723   [#942](https://github.com/rust-lang/mdBook/pull/942)
 724 - 🔥 Updated to pulldown-cmark 0.5. This may have significant changes to the
 725   formatting of existing books, as the newer version has more accurate
 726   interpretation of the CommonMark spec and a large number of bug fixes and
 727   changes.
 728   [#898](https://github.com/rust-lang/mdBook/pull/898)
 729 - The `diff` language should now highlight correctly.

 763 [2c20c99...6cbc41d](https://github.com/rust-lang/mdBook/compare/2c20c99...6cbc41d)
 764
 765 ### Added
 766 - Added an optional button to the top of the page which will link to a git
 767   repository. Use the `git-repository-url` and `git-repository-icon` options
 768   in the `[output.html]` section to enable it and set its appearance.
 769   [#802](https://github.com/rust-lang/mdBook/pull/802)
 770 - Added a `default-theme` option to the `[output.html]` section.
 771   [#804](https://github.com/rust-lang/mdBook/pull/804)
 772
 773 ### Changed
 774 - 💥 Header ID anchors no longer add an arbitrary `a` character for headers
 775   that start with a non-ascii-alphabetic character.
 776   [#788](https://github.com/rust-lang/mdBook/pull/788)
 777
 778 ### Fixed

 784 ## mdBook 0.2.2 (2018-10-19)
 785 [7e2e095...2c20c99](https://github.com/rust-lang/mdBook/compare/7e2e095...2c20c99)
 786
 787 ### Added
 788 - 🎉 Process-based custom preprocessors. See [the
 789   docs](https://rust-lang.github.io/mdBook/for_developers/preprocessors.html)
 790   for more.
 791   [#792](https://github.com/rust-lang/mdBook/pull/792)
 792
 793 - 🎉 Configurable preprocessors.
 794
 795   Added `build.use-default-preprocessors` boolean TOML key to allow disabling
 796   the built-in `links` and `index` preprocessors.
 797
 798   Added `[preprocessor]` TOML tables to configure each preprocessor.
 799
 800   Specifying `[preprocessor.links]` or `[preprocessor.index]` will enable the
 801   respective built-in preprocessor if `build.use-default-preprocessors` is
 802   `false`.
 803
 804   Added `fn supports_renderer(&self, renderer: &str) -> bool` to the
 805   `Preprocessor` trait to specify if the preprocessor supports the given
 806   renderer. The default implementation always returns `true`.
 807
 808   `Preprocessor::run` now takes a book by value instead of a mutable
 809   reference. It should return a `Book` value with the intended modifications.
 810
 811   Added `PreprocessorContext::renderer` to indicate the renderer being used.

 823 ## mdBook 0.2.1 (2018-08-22)
 824 [91ffca1...7e2e095](https://github.com/rust-lang/mdBook/compare/91ffca1...7e2e095)
 825

 832   [#765](https://github.com/rust-lang/mdBook/pull/765)
 833
 834 ## mdBook 0.2.0 (2018-08-02)
 835
 836 ### Changed
 837 - 💥 This release changes how links are handled in mdBook. Previously, relative
 838   links were interpreted relative to the book's root. In `0.2.0`+ links are
 839   relative to the page they are in, and use the `.md` extension. This has [several
 840   advantages](https://github.com/rust-lang/mdBook/pull/603#issue-166701447),
 841   such as making links work in other markdown viewers like GitHub. You will
 842   likely have to change links in your book to accommodate this change. For
 843   example, a book with this layout:
 844
 845   ```
 846   chapter_1/
 847       section_1.md
 848       section_2.md
 849   SUMMARY.md
 850   ```
 851
 852   Previously a link in `section_1.md` to `section_2.md` would look like this:
 853   ```markdown
 854   [section_2](chapter_1/section_2.html)
 855   ```
 856
 857   Now it must be changed to this:
 858   ```markdown
 859   [section_2](section_2.md)
 860   ```
 861
 862 - 💥 `mdbook test --library-path` now accepts a comma-delimited list of
 863   arguments rather than taking all following arguments. This makes it easier
 864   to handle the trailing book directory argument without always needing to put
 865   ` -- ` before it. Multiple instances of the option continue to be accepted:
 866   `mdbook test -L foo -L bar`.
 867
 868 - 💥 `mdbook serve` has some of its options renamed for clarity. See `mdbook
 869   help serve` for details.
 870
 871 - Embedded rust playpens now use the "stable" playground API.
 872   [#754](https://github.com/rust-lang/mdBook/pull/754)
 873
 874 ### Fixed
 875 - Escaped includes (`\{{#include file.rs}}`) will now render correctly.
 876   [f30ce01](https://github.com/rust-lang/mdBook/commit/f30ce0184d71e342141145472bf816419d30a2c5)
 877 - `index.html` will now render correctly when the book's first section is
 878   inside a subdirectory.
