I've uploaded a new version to Steam and the TGC downloads area with the following changes
* Added clipboard support to the Linux version
* Increase max local notifications to 100
* Fixed CopyNetworkMessage failing to copy messages that were not fully read
* Copied network messages can now be read and added to
* Added AddNetworkMessageBye and GetNetworkMessageByte
* Deprecated SetScreenResolution due to lack of support in newer renderers
* Added an error if the Mod command is used with a divisor of 0 to avoid a crash
* iOS now defaults to allowing audio from background apps to continue
* iOS Tier 2 projects have been updated to use launch storyboards instead of images
* iOS export has been updated to use a launch logo instead of a splash image, the logo will be centered on screen in any orientation
* Added Vulkan support to iOS
* Added Vulkan support to Mac
* Added Vulkan support to Linux
* Added partial Vulkan support to Android, PlayVideoToImage, SetDeviceCameraToImage, and AR are not supported with Vulkan
* The Android player will always use OpenGL ES for maximum compatibility, exported apps can choose to use Vulkan by using #renderer "Advanced"
* On all platforms, any device that does not support Vulkan will drop back to OpenGL automatically
* Fixed shadows not working on the Windows Vulkan renderer if depth clamping is not available
* Fixed SetShadowCascades not applying the given values
* Modified shadow algorithm so that the shadow bias can now be set much lower for cascade shadow maps, reducing the gap between objects and shadows
* Improved Android background behaviour so apps will pause and resume faster when sent to background
* Updated Android to target API 29 as required by Google
* Added FixCameraToObject command
* Added GetCameraWorldX/Y/Z commands to get the world coordinates of cameras attached to objects
* IDE: Fixed an error where the Android APK export feature would lock up from time to time
* IDE: Fixed export of APK or IPA. Could hang on second and subsequent attempts
* IDE: Fixed unzipping issue - 64-bit unzip with passwords
* IDE: Added undo to rotations actions
* IDE: Fixed Undo/Redo when using properties widgets
* IDE: Improved performance when using event based rendering
* IDE: Make sure all properties changes are saved
* IDE: Pressing Control+D in the IDE can sometimes cause a crash in the IDE
* IDE: Fixed a random crash when right clicking on an item and then choosing go to definition
* IDE: Now display the normal mouse pointer when over scrollbars
* IDE: Reset the cursor position when closing/opening a agc file
* IDE: Make sure code properties parameters entries are correct before opening the code properties window
* IDE: Created a larger area to select line text, when mouse over line numbers. margin moved a little bit.
* IDE: Fixed - Goto Definition search order, current file - open files in current project - open files all projects - all files current project - all files.
* IDE: Fixed - Sometimes CTRL-Tab didn't work as it should, this has been recoded and should much better now.
* IDE: Auto complete would sometimes hide the line you are typing
* IDE: Fixed an issue where Close Source File would not work on a new Source File
* IDE: Added - "Go To Definition" Scan for same files already opened in a tab, even if not in same project.
* IDE: Fixed - Pasting code at end of file caused the editor to jump to the first line
* IDE: Fixed multiple issues with scene editor (https://github.com/TheGameCreators/AGK-Studio/issues/619)
The biggest change is that iOS, Mac, Linux, and Android all now have a Vulkan renderer in addition to the OpenGL renderer as a fallback. Android doesn't have full support for it as PlayVideoToImage, SetDeviceCameraToImage, and AR don't work with Vulkan, so the Android player will default to OpenGL for now. But you can use Vulkan in your exported apps by using #renderer "Advanced" in your Tier 1 code if you don't need any of these commands. On Android using #renderer "Advanced" will still fall back to OpenGL if Vulkan isn't supported.
Also Apple have made this release very difficult for us as they have introduced new notarization requirements that mean we currently cannot do Android export in the Mac version. We've also seen at least one machine force the IDE to run in a sandbox which breaks local app running, so if you experience any issues please let us know.
Edit (14/04/2020): I've uploaded a new version for Mac that should fix the sandbox issue, and restore Android export by downloading the Android export files separately. The download will begin when you open the Android Export dialog for the first time.
