 // -Reintroduction of RAII bindings to help protect the host's context state.
 // -Added file parameters
 //
+// FFGL 2.2 by Menno Vink (menno@resolume.com)
+// www.resolume.com
+// -Added context state validation in debug builds. This provides plugin developers hints on which context state they need to restore.
+// -Removed default DllMain implementation so that plugins may implement it without changing the ffgl library.
+// -File parameters now accept an initial value just like text parameters.
+//  (This requires Resolume 7.2 for it to be picked up)
+// -Added support for grouping parameters together. Set a parameter's group with SetParamGroup,
+//  any cosecutive params with the same group will be listed under the same collapsable region
+//  (This requires Resolume 7.3.0 for it to be picked up)
+// -Added support for top-left texture orientation. Hosts that are rendering with the top-left texture orientation currently need to flip
+//  both inputs and the output every frame. A plugin can now inform the host that it supports the top-left orientation by setting supportTopLeftTextureOrientation to true.
+//  If the host wants to use it then it'll inform the plugin, which can query if it should use top-left or bottom-left using the GetTextureOrientation function.
+//  (This requires Resolume 7.3.1 for it to be picked up)
+// -Added support for hooking into the host's logging system from the plugin, enabling a plugin's log messages to be interleaved with the host's messages in the host's log file.
+//  (This requires Resolume 7.3.1 for it to be picked up)
