This commit adds a skeleton of "Ruby on Rails 6.0 Release Notes". It isn't a good time to add changelogs' entries to this guide since we can redo/revert some things till the final release 6.0. It would be better to do it close to the release. But we already can add mentions about major features that have been added to 6.0. I added mention about "Parallel Testing".

Upgrading to Rails 6.0
|
|
----------------------
|
|
|
|
If you're upgrading an existing application, it's a great idea to have good test
|
|
coverage before going in. You should also first upgrade to Rails 5.2 in case you
|
|
haven't and make sure your application still runs as expected before attempting
|
|
an update to Rails 6.0. A list of things to watch out for when upgrading is
|
|
available in the
|
|
[Upgrading Ruby on Rails](upgrading_ruby_on_rails.html#upgrading-from-rails-5-2-to-rails-6-0)
|
|
guide.
|
|
|
|
Major Features
|
|
--------------
|
|
|
|
### Parallel Testing
|
|
|
|
[Pull Request](https://github.com/rails/rails/pull/31900)
|
|
|
|
[Parallel Testing](testing.html#parallel-testing) allows you to parallelize your
|
|
test suite. While forking processes is the default method, threading is
|
|
supported as well. Running tests in parallel reduces the time it takes
|
|
your entire test suite to run.
