If everyone updated to 4.2.8 right after it was released, a large
fraction of the pool servers would likely be down. There were (and
apparently still are) some bugs that caused ntpd to crash on busy
servers.

If the 4.2.6-4.2.8 diff was just bug fixes and nothing else, I think
the downstream packagers would be quicker in rebasing to the new
version. But there are incompatibilies and new bugs, known and
unknown. Trying to force downstream packagers to rebase is not likely
going to work.

How many of those >1000 bugs are actually in 4.2.6 and how many of
them are important? To me it looks like a lot of them were bugs
introduced in the 4.2.7 development. There are commits with unrelated
changes mixed together, with no comments, so it may not be easy to
determine whether something is actually a bug fix.
