"UPD" suggests you’ve found the updated 2022-2023 patch. Early vinyl pressings of the 2022 set had a defect on "She Said She Said" (a missing high-frequency harmonic). The digital "UPD" (Update) corrects this, incorporates slight phase adjustments on "Here, There and Everywhere," and repackages the FLACs with proper metadata.
This is the main event. Using MAL (Machine Audio Learning) technology—the same source separation used for the Get Back documentary—Martin and Okell extracted individual instruments from the mono master. Listen to the 88.2 FLAC of Taxman: Paul McCartney’s bass growls with a subsonic punch that the 1966 stereo mix buried. Eleanor Rigby’s strings are no longer a murky wash; you hear the rosin on the bows. Yellow Submarine has sound effects ping-ponging in true stereo space.

Ideally, the studio masters for recordings from 1966 were recorded on 4-track tape. While tape has infinite frequency response, the transfer to 88.2 kHz ensures that no digital artifacts interfere with the analog warmth.
