Critical Update for iOS 14.0 users

New:
- Support for iOS 14.0

Fixed:
- Bug causing the app to crash
- Functionality with ST02A while using iOS 14 that resulted in camera preview not behaving as expected

Scanner v2.0

- Battery depleted events are no longer sent when the device hits 10% if the user started scanning above 10% battery charge remaining.

- Resolved an issue with exporting textured meshes as OBJ. The resulting texture JPG will no longer contain a numerical suffix.

Scanner v1.12

- Structure Sensor (Mark II) Firmware 1.0 support

- Fixed misc. crashing related to background and foreground app transitions (using Structure Sensor (Mark II) with Firmware 1.0)

- Fixed misc. crashing and failures related to starting and stopping streaming (using Structure Sensor (Mark II) with Firmware 1.0)

- Low battery notifications will now be sent during scanning (using Structure Sensor (Mark II) with Firmware 1.0)

Scanner v1.11.2:

- Fixed a bug where Structure Sensor (Mark II) would either fail to stream after restarting or switching streams several times, or the frame rate would slow down every time streaming would restart.

Scanner v1.11:

- Structure Sensor (Mark II) connection and stability have been greatly improved
- An in-app notification has been added to inform you when a firmware update is available for your Mark II sensor
- Resolved a crash that would happen when the camera permissions dialog box appears for the first time
- Fixed a bug where apps would crash when backgrounded by the OS
- Fixed a bug where Structure Sensor (Mark II) would not reconnect after an app was backgrounded
- Fixed a bug where unplugging and replugging Structure Sensor (Mark II) would crash the application

Scanner 1.10.2:

- Improved Structure Sensor (Mark II) battery state checking - apps no longer report that Mark II requires charging when the battery level is at 60% or below.
- Improved handling of Structure Sensor (Mark II) disconnection events - apps no longer freeze when Mark II is disconnected due to being unplugged or battery depletion.

Release Version 1.10

- A new settings menu has been introduced. It can be found by pressing the settings gear icon in the top left corner. Examples of this are changing the exposure and gain settings on the IR camera, to better adjust to different lighting conditions in your scans.
- Some UI elements have been shifted or resized to better fit in iPhone layouts.- Some UI buttons have been given updated graphics. We hope you like our new icons!
- We have also introduced the concept of sensor depth stream presets. These presets are a work-in-progress, but should provide better depth coverage when doing body-scanning or scanning outdoors. Select these options (i.e. Default, Body-Scanning, Outdoors) from the settings gear in the top left corner of the app.
- A new calibration overlay has been added to the Scanner sample that provides better instructions for calibrating when approximate calibrations are not available, e.g. when using custom iPhone cases.
- A bug has been fixed where backgrounding the app or receiving a notification could crash the app.

Version 1.9.1 - Now with approximate default calibration for 2018 iPad Pro devices, allowing quick usage prior to running Calibrator. - Fixed a bug on iPhone devices where calibration overlay would not disappear even after calibrating. - Fixed a bug where OCC files would be written to the app documents directory after every scan.
