I was puzzled by this as well. He seems to have overhauled the 5th in 1995, but I don't know quite to what extent.
I really hope Mode Records will complete their Rădulescu cycles with Stephen Clarke and the JACK Quartet. I did find it worrying that the composer's widow, the cellist Catherine Marie Tunnell, had to Kickstart The Complete Cello Works, which came out last year with Mode as vol. 3 of the Rădulescu Edition.
