It's been two years since we moved to a regular deprecation schedule. And thanks to developers like you, we've been able to regularly release new versions and features while maintaining code health.
To continue this trend, we'll be simplifying the sunset schedule by tightening our belts a little. Starting with v201511, versions will be sunset one year after release. This will help us reduce the number of out-of-band deprecations. A shorter lifecycle means dated features can ride off into the sunset as intended. Plus, it's easy to remember when the version you're using is about to bite the dust, even if you're not signed up for deprecation announcements or don't obsessively check our deprecation schedule.
We strive to make upgrades easy. If you think they're not, please tell us why on our developer forum so we can make it better.
