Hopefully the final update before 11.0-BETA2 is rolled, there have been
a number of commits, reverts, commits, reverts, etc., to the callout(9)
code recently.

What we think will be the final update to the TCP panic issue has been
committed as r303098, and numerous iterations of the final change tested
by Larry Rosenman (and thank you, Larry!).

Given the timeframe over which this change has been tested, the plan is
to merge r303098 to stable/11 tomorrow, and finally roll 11.0-BETA2,
provided none of our many "canaries" report issues in the meantime (and
thank you to those "canaries" for continuously testing!).

I am confident the testing is conclusive on resolving the issues.
I hope I am not wrong.

However, another issue has been brought to re_at_ attention, that could
potentially affect the ABI.  The details are still being investigated,
however this is not a blocker for BETA2 as it stands now.

The schedule on the website has intentionally not been updated yet, but
I hope to expect to kick the 11.0-BETA2 builds at 00:00 UTC July 22.

Again, thank you all for your patience, as the issues blocking BETA2 are
non-trivial, and after the final release is rolled, more difficult to
resolve.
