 - Process : Removed non-const variant of the `handleException()` method.
 - StringPlug : Removed deprecated `precomputedHash` argument from `getValue()` method.
 - OpenColorIOContext : Removed `configEnabledPlug()`, `configValuePlug()`, `workingSpaceEnabledPlug()` and `workingSpaceValuePlug()` methods. Use the OptionalValuePlug child accessors instead.
+- Windows launch script : Removed the hardcoded `/debugexe` switch used when `GAFFER_DEBUG` is enabled, making it possible to use debuggers other than Visual Studio. Debug switches can be added to the `GAFFER_DEBUGGER` environment variable instead.
