In today's release, we've updated Flash Player to address a bug that was impacting some Flash content. If you are having problems interacting with mouse button presses or drag and drop actions, we recommend you update to today's release.
The Adobe - Flash Player page is always updated with the latest version whenever a new version is released. Based on this information, Microsoft is sticking with 26.0.0.120.
