The PageThumbs deprecation warning says: PageThumbs.getFileForURL is deprecated. Please use PageThumbs.getFilePathForURL and OS.File This is incorrect. It should be: PageThumbsStorage.getFileForURL is deprecated. Please use PageThumbsStorage.getFilePathForURL and OS.File I realize this is only for one release, but it is quite confusing.
This has been deprecated (and documented wrong) for 23 releases now. At what point do we remove deprecated things?
