Re: so....
Yes!
UDF support was first included in v4.59 beta (released in 2008) and hence would have been included in formal releases 4.63 and later, specifically the long-term stable release and hence widely used v9.20 (released in 2010).
However, what is going to be problemmatic, isn't upgrading the standalone installed version (ie. the version in folder c:\program files\7-zip\ ), but all those versions that vendors have bundled with their applications, for example:
C:\Program Files (x86)\Trend Micro\Client Server Security Agent\7z.*
