Package: ulogd2
Version: 2.0.8-3
Severity: normal

Dear Maintainer,

- I'm using ulogd2 for NFCT (conntrack) event logging on a NAT gateway, which
  logs all new connections for abuse reporting reasons.

- When using GPRINT (key=value) output format, IPv6 addresses are completely
  absent. This makes the logs rather incomplete. (IPv4 events still work
  correctly.)

- This was fixed upstream in ulogd2 commit f04bf6794d11 and several following
  commits, in 2023, which appear to be present in upstream release 2.0.9
  (released in May).

- I've been running a local build from git, as workaround, for the last year.
