What is P6?

Hi,

P6 was an internal release generated for a particular ISC support customer
(which OpenBSD is not).  As P6 was generated around Y2K time, we decided to
defer the public release.  We have since been accumulating some additional
patches and will be releasing 8.2.3 ASAP but have been resource limited as
BINDv9 beta 1 is due out this week.  
BTW: if anyone is looking for a DNS related job, please contact me... :-)

The major issues addressed in P6 were a possible denial of service problem
that could exist when querying for SIG records from a secure zone and a bug
that, under very heavy load, could result in a flood of notifies.  If we were
aware of any significant security related issues, we would have released P6
long before now.
