No there is no up-to-date package, but the "old" one works fine just doesn't support syntax highlight for the newer functions and snippets.
I might work on an updated version of it it is quite easy to do.
Edit: I recommend adjusting the papyrus.sublime-build file to allow building your source files directly from sublime
here is the one i use currently:
Spoiler {"cmd": [ "D:\\Spiele\\Steam\\SteamApps\\common\\Skyrim\\Papyrus Compiler\\PapyrusCompiler.exe","$file","-i=D:\\Spiele\\Steam\\SteamApps\\common\\Skyrim\\Data\\Scripts\\Source;$file_path","-o=D:\\Spiele\\Steam\\SteamApps\\common\\Skyrim\\Data\\Scripts","-f=TESV_Papyrus_Flags.flg"],"file_regex": "(^.*\\.psc)\\(([0-9]*),([0-9]*)\\)","selector": "source.papyrus"}
With this build file you can store your source files outside of the Skyrim/Data folder
