ChangeLog
=========

0.4.0 (2016-03-01)
------------------
* Crowbook now internally uses a true YAML parser, `yaml_rust`, for its
  options. Since the "old" Crowbooks's config format was similar, but
  had some subtle differences, this is somewhat of a breaking change:
    * strings should now be escaped with "" in some cases (e.g. if it
      contains special characters). On the other hand, it *allows* to
      optionally escape a string with these quotes, which wasn't
      possible until then and might be useful in some cases.
    * multiline strings now follow the YAML format, instead of the
      previous "YAML-ish" format. This can impact the way newlines are
      added at the end of a multiline string. See
      e.g. [this link](http://stackoverflow.com/questions/3790454/in-yaml-how-do-i-break-a-string-over-multiple-lines)
      for the various ways to include mulitiline strings in Yaml.
* Crowbook now parses YAML blocks (delimited by two lines with "---")
  in Markdown files, ignoring keys that it doesn't recognize. This
  allows crowbook to be compatible(-ish) with Markdown that contains
  YAML blocks for Jekyll or Pandoc.
* New option `--single` allows to give Crowbook a single Markdown file
  (which can contain options within an inline YAML block) instead of a
  book configuration file. This is useful for e.g. short stories.
* Enhanced the way debugging/warning/info messages are handled and
displayed:
    * Added a `--debug` option to the binary.
    * Internal: added a `Logger` struct.
    * Different levels of information (debug/warning/info/error) get
      different colours.
* Bugfixes:
    * Crowbook no longer crashes when called with the `--to` argument
      if it can't create a file. 


0.3.0 (2016-02-27)
------------------
* Crowbook now tries to convert local links. That is, if you link to a
  Markdown file that is used in the book.
  (e.g. [README.md](README.md)), it *should* link to an appropriate
  inner reference inside the book.
* Latex renderer now supports (local) images.
* Epub renderer now embed (local) images in the EPUB file.
* Some changes to the HTML/Epub stylesheets.
* Internal (or usage as a library):
    * Crowbook no longer changes current directory, which worked in
      the binary but could cause problem if library was used in
      multithreaded environment (e.g. in `cargo test`).
    * More modules and methods are now private.
    * Improved documentation.
    * Added more unit tests.
* Bugfixes: 
    * Epub renderer now correctly renders unnumbered chapter without a
      number in its toc.ncx file



0.2.2 (2016-02-25)
------------------
* Bugfixes:
    * French cleaner now correctly replaces space after — (in
      e.g. dialogs) with "em space".


0.2.1 (2016-02-25)
------------------
* Bugfixes:
    * HTML/Epub rendering no longer incorrectly increment chapter
      count for unnumbered chapters.
    * Latex: makes what is possible to avoid orverflowing the page.
* Minor changes:
    * Latex: improvement of the default way URLs are displayed.
      

0.2.0 (2016-02-25) 
------------------
* Command line arguments:
    * New argument `--print-template` now allows to print a built-in
      template to stdout. 
    * New argument `--list-options` prints out all valid
      options in a config file (or in `set`), their type and default
      value.
    * New argument `--set` allows to define or override whatever
      option set in a book configuration.
    * `--create` can now be used without specifying a `BOOK`, printing
      its result on `stdout`.
* Configuration file:
    * Added support for multiline strings in `.book` files, with
      either '|' (preserving line returns) or '>' (transforming line
      returns in spaces) 
    * New option `display_toc` allows to display the table of contents
      (whose name, at least for HTML, is specified by `toc_name`) in
      HTML and PDF documents.
    * Option `numbering` now takes an int instead of a boolean,
      allowing to specify the maximum level to number (e.g. `1`:
      chapters only, `2`: chapters and sectino, ..., `6`: everything).
* Rendering: 
    * Added support for numbering all headers, not just level-1 (e.g.,
      having a subsection numbered `2.3.1`).
    * Tables and Footnotes are now implemented for HTML/Epub and LaTeX
    output.
* Internal:
    * Refactored `Book` to use an HashMap of `BookOption`s instead of
      having like 42 fields.
