In particular, using the "all" package (which includes source) allows
IntelliJ IDEA to provide autocompletion and other nice features that
are unavailable when using the "bin" package.
This follows an IntelliJ IDEA recommendation. Having the full
distribution allows IntelliJ IDEA to provide contextual help,
autocompletion, etc. for Gradle build scripts. The disadvantage, I
suppose, is that it imposes a larger download time on first use of
"gradlew".
New features that I like from this release: (1) better output grouping
when building in parallel, and (2) automatic test ordering to try
previously-failing tests first.
