Comment 1 Bernhard Rosenkraenzer 2002-01-18 13:23:32 EST
Not quite.

7.1 shipped with bind 9.1.0
7.2 shipped with bind 9.1.3

7.0 is still at 8.2.3 though.
Comment 2 Bernhard Rosenkraenzer 2002-01-18 13:26:32 EST
And (just checked) 8.2.3 does NOT have this bug. The last version with this
problem was 8.2.2p7, according to the page you mentioned yourself.
Comment 3 Landon Curt Noll 2002-01-18 13:58:13 EST
The page does mention 8.2.3-betas, which is later than 8.2.2p7.

Is 8.2.3-1 based on one of the 8.2.3-betas?
Comment 4 Bernhard Rosenkraenzer 2002-01-18 14:00:35 EST
No, it's based on 8.2.3-RELEASE.
