Latest Ogg Vorbis dll does not include delete ogg vorbis command anymore. I checked the dll file with the tool that displays all functions within specified dll and it did not found this command too.
How can we delete ogg vorbis now? There is a load command but there is no delete command, now that is a shame.
I also noticed that encode to ogg vorbis have some problems too. Please check my earlier bug report on this specific command.
Enhancements Expansion pack now is totally useless, probably, the only command set which is working quite okay is the file block commands, rest of the command groups have a lot of problems.
