Ruby 2.6.6 has reached the end-of-life and I had some trouble
installing the dependencies locally as a result. I've updated to the
latest version of ruby and regenerated the Gemfile.lock with the
latest versions of the two gems we depend on, and their dependencies.
Everything looks to still be working in terms of site generation.
This fixes the deprecation warning (see below) which appears on running
a fresh `bundle install`. This branch contains the changes described in
this PR [1]. The only outstanding problems seem to be Windows-related,
so I think it's safe to use it.
We should be able to switch back to the release version (required by
default by the jekyll gem) when this PR is merged and released.
Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.
* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
primary implementation: https://sass-lang.com/install
* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
sassc gem: https://github.com/sass/sassc-ruby#readme
* For more details, please refer to the Sass blog:
