  +## News

  +While you're away for the holiday season, we're going to be making a few improvements to the Azure REST API Specs repository:
  +
  + - We will stop merging PRs until the new year starting on **6:00 p.m. December 20th, 2017**.
  + - Starting on **December 21st, 2017**, we will be restoring `master` as the default branch for this repository.
  + - All open PRs will automatically be updated to target `master` instead of `current`.
  + - We will stop accepting contributions to the `current` branch.
  + - On **December 21st, 2017**, we will merge a refactoring of this repository where we introduce `preview` and `stable` directories to differentiate Swaggers and services that are ready for General Availability and those that are not yet.
  + - Beginning **December 21st, 2017**, the `master` branch in the private repository will become a read-only copy of the `master` branch in the public repository.
