"A compatible version of Wireshark" would either be "a version of Wireshark that can read pcap-NG files" or "a version of Wireshark that, when capturing, can capture into a pcap-NG file", depending on what you mean by "using PCAP-NG".

1.6.5 can read pcap-NG files (the first release of Wireshark with pcap-NG support, including support for capturing into a pcap-NG file, was 1.2.0), and there is a binary release of 1.6.5.

There might not have been many requests for additions to the pcap-NG format, although I did send some mail noting that the spec needs to clarify whether the UTF-8 strings in various options are supposed to be null-terminated as well as counted, and haven't received a reply yet.

If by "upgrading PCAP to PCAP-NG" - "PCAP" and "PCAP-NG" aren't pieces of software that you'd update in that sense, they're file formats - you mean "selecting pcap-NG format when you're capturing", that should work.
