"somebody remind me to update this date every year so the docs appear current"

This is for a yearly update as it broke some tests for a totally unrelated issue few packages down the chain:

• https://github.com/gruntjs/grunt-contrib-pug/pull/173

Note: to be fair, that's the doc with a notice which should have given a clue to the maintainer of grunt-contrib-pug as not to use it for testing.
