Hello Jekyllers!

It’s time for yet another release that includes enhancements, optimizations and bug-fixes. Highlights of this release are:

• Jekyll now supports rendering excerpts for pages in addition to documents and posts.
• The where_exp filter got enhanced. Earlier, one could just use either and or or once per expression. Now, one may use those binary operators multiple times in the filter’s expression.
• Jekyll has a new set of filters based on its flavor of the where and where_exp filters. Named find and find_exp filters respectively, they work similar to their ancestors except that they return the first object that satisfies the given conditions.
• Jekyll’s number_of_words filter can now take an optional argument to better count words of text containing Chinese, Japanese or Korean characters.
• One may now use :slugified_categories in their permalink configurations to generate a more apt URL (categories are downcased and non-alphanumeric characters replaced by dashes) for their for posts and documents.
• The logic for slugifying a given string has been enhanced to support more Unicode characters.
• If you face issues from Jekyll importing a config file bundled within a theme, you can now disable the import entirely by setting ignore_theme_config: true in your site’s configuration file.
• If you face issues from Jekyll’s disk-caching feature, you can now disable the mechanism without opting to build in safe mode, by either setting disable_disk_cache: true in your configuration file or by passing the CLI switch --disable-disk-cache to jekyll build or jekyll serve commands.
• When you build a site with the --profile switch, Jekyll will now additionally output a small table showing the amount of time taken during various stages of the build process.
• Jekyll’s development server now supports certificates based on Elliptic-curve cryptography.

For the interest of plugin authors:

• Jekyll::Page now uses a Liquid Drop to expose attributes for Liquid templates. However, its subclasses will continue using the legacy ATTRIBUTES_FOR_LIQUID hash by default. More details in the associated documentation
• Excerpts won’t be generated for Jekyll::Page subclasses automatically unless such instances have an excerpt key in their data hash.

For the interest of gem-based theme authors:

• From v4.1.0 onwards, a newly generated theme workspace (via jekyll new-theme ...) will have the gemspec configured to bundle a _config.yml at the root of the workspace. If you don’t wish to include the configuration file in the released gem, please remove |_config\.yml from the regular expression in the gemspec.
