Regarding webglcontext, it looks like HandleWebGLContextLoss() has been removed from construct.net/en/make-games/manuals/addon-sdk/runtime-reference/base-classes/sdkworldinstancebase
Is there a new way to enable the custom options for handling webgl context loss / restore (the spine addon may need this)?
It should keep working - if any breaking changes happen that aren't clearly noted please file an issue for them as they are probably accidental.
