OpenSSL in Debian Unstable drops TLS 1.0/1.1 support (

Kurt just uploaded a version of OpenSSL to unstable that disables
the TLS 1.0 and 1.1 protocol. This currently leaves TLS 1.2 as the
only supported SSL/TLS protocol version.

This will likely break certain things that for whatever reason
still don’t support TLS 1.2. I strongly suggest that if it’s not
supported that you add support for it, or get the other side to
add support for it.

OpenSSL made a release 5 years ago that supported TLS 1.2. The
current support of the server side seems to be around 90%. I hope
that by the time Buster releases the support for TLS 1.2 will be
high enough that I don’t need to enable them again.

WASHINGTON — A week ago, the White House declared that ordering an American aircraft carrier into the Sea of Japan would send a powerful deterrent signal to North Korea and give President Trump more options in responding to the North’s provocative behavior. “We’re sending an armada,” Mr. Trump said to Fox News that afternoon.

The problem was that the carrier, the Carl Vinson, and the three other warships in its strike force were that very moment sailing in the opposite direction, to take part in joint exercises with the Australian Navy in the Indian Ocean, 3,500 miles southwest of the Korean Peninsula.
