Hello Jekyllers!
 | 
						|
 | 
						|
The Jekyll team is happy to announce the release of `v4.2.1` which fixes a couple of
 | 
						|
regressions introduced in `v4.2.0` and another bug inherited from Jekyll 3.
 | 
						|
 | 
						|
In `v4.2.0`, we decided to stop overriding {% raw %}`{{ site.url }}`{% endraw %} with
 | 
						|
the *localhost* address when running the command `jekyll serve` with the default
 | 
						|
*development* mode. While the intent behind the change was to avoid forcing users to
 | 
						|
generate a *production build* separately by invoking `jekyll build`, it however had an
 | 
						|
unforeseen consequence — absolute URLs for assets now pointed to
 | 
						|
resources that were at times not yet been deployed to the configured `site.url`. That
 | 
						|
broke the users' local development workflow.
 | 
						|
 | 
						|
`v4.2.0` also added a series of optimizations surrounding the generation of Liquid
 | 
						|
representation for a site's standalone pages and layouts. However, that prevented
 | 
						|
{% raw %}`{{ page.content }}`{% endraw %} and other mutable attributes from reflecting
 | 
						|
the latest state of the requested attribute, thereby breaking the render of all resources
 | 
						|
that were dependent on such mutable attributes.
 | 
						|
 | 
						|
The last fix included in this release addresses the issue where incremental regeneration
 | 
						|
ignored changes to documents in collections when the site is configured to use a custom
 | 
						|
`collections_dir` for all collections.
 | 
						|
 | 
						|
Special thanks to @benik for helping us understand the regression caused by the decision
 | 
						|
to stop overriding `site.url` and proposing to revert the change. Another special thanks
 | 
						|
to @pdmosses for helping us discover the regression surrounding Liquid representation of
 | 
						|
pages by providing with a test repository.
