ARCore SDK for iOS v1.6.0

Added the ability to target iOS versions prior to 11.0. The binary now contains
32-bit architectures, and the README documents three version numbers: minimum
deployment target, minimum base SDK, and minimum version for runtime support.

• Added support for devices:
  • iPhone: XS, XS Max, XR.
  • iPad Pro: 11 inch, 12.9 inch (3rd gen).

ARCore SDK for iOS v1.5.0

Added the ability for new devices to be supported without an SDK update.

Resolved Issues:

• Fixed an issue where ARCore would not compile if used with Firebase
  Firestore.

ARCore SDK for iOS v1.4.0

Resolved Issues:

• Fixed an issue where hosting and resolving Cloud Anchors would fail on
  iOS 12 with the new 4:3 aspect ratio.

ARCore SDK for iOS v1.3.0

Adds support for ARKit-compatible iPads. These include:

• iPad: 5th and 6th generation
• iPad Pro: 12.9 inch (1st and 2nd gen), 10.5 inch, 9.7 inch

Resolved Issues:

• Fixed an issue where an invalid API key for the ARCore Cloud Anchor Service
  would result in a cloud anchor state of GARCloudAnchorStateErrorInternal.
  The error state will now be GARCloudAnchorStateErrorNotAuthorized.

ARCore SDK for iOS v1.2.1

Resolved Issues:

• Removed SDK references to ARFaceAnchor. The hostCloudAnchor:
  implementation no longer checks that the passed in ARAnchor is not an
  ARFaceAnchor, and no longer forcibly exits with
  GARSessionErrorCodeAnchorNotSupportedForHosting. However, use of
  ARFaceAnchors remains unsupported in this release.

ARCore SDK for iOS v1.2.0

Initial release alongside ARCore 1.2 on Android.

• Support for Cloud Anchors.
• Supported devices: iPhone X, 8, 8+, 7, 7+, 6S, 6S+, SE.

Known Issues:

• An invalid API key for the ARCore Cloud Anchor Service will result in a
  Cloud Anchor state of GARCloudAnchorStateErrorInternal instead of
  GARCloudAnchorStateErrorNotAuthorized. This is a known issue and will be
  fixed in an upcoming release.
