We just published ConstraintLayout 1.1.0 beta 5. We consider it the release candidate for 1.1.0 stable. It’s available from the google maven repository:

dependencies {
    compile 'com.android.support.constraint:constraint-layout:1.1.0-beta5'
}

Documentation is available on https://developer.android.com/reference/android/support/constraint/ConstraintLayout.html

Changes:

  • Fix barrier issues (wrap_content behavior)
  • Added missing ConstraintSet.constrainCircle() method
  • Chain RTL behavior fix
