556 //
557 // 1.0.0 - initial release
558 // 1.0.1 - Bugfix: IsFrameCapturing() was returning false for captures that were triggered
559 //         by keypress or TriggerCapture, instead of Start/EndFrameCapture.
560 // 1.0.2 - Refactor: Renamed eRENDERDOC_Option_DebugDeviceMode to eRENDERDOC_Option_APIValidation
561 // 1.1.0 - Add feature: TriggerMultiFrameCapture(). Backwards compatible with 1.0.x since the new
562 //         function pointer is added to the end of the struct, the original layout is identical
563 // 1.1.1 - Refactor: Renamed remote access to target control (to better disambiguate from remote
564 //         replay/remote server concept in replay UI)
565 // 1.1.2 - Refactor: Renamed "log file" in function names to just capture, to clarify that these
566 //         are captures and not debug logging files. This is the first API version in the v1.0
567 //         branch.
568 // 1.2.0 - Added feature: SetCaptureFileComments() to add comments to a capture file that will be
569 //         displayed in the UI program on load.
570 // 1.3.0 - Added feature: New capture option eRENDERDOC_Option_AllowUnsupportedVendorExtensions
571 //         which allows users to opt-in to allowing unsupported vendor extensions to function.
572 //         Should be used at the user's own risk.
573 //         Refactor: Renamed eRENDERDOC_Option_VerifyMapWrites to
574 //         eRENDERDOC_Option_VerifyBufferAccess, which now also controls initialisation to
575 //         0xdddddddd of uninitialised buffer contents.
576 // 1.4.0 - Added feature: DiscardFrameCapture() to discard a frame capture in progress and stop
577 //         capturing without saving anything to disk.
578 // 1.4.1 - Refactor: Renamed Shutdown to RemoveHooks to better clarify what is happening
579 // 1.4.2 - Refactor: Renamed 'draws' to 'actions' in callstack capture option.
