"Our TLBleed exploit successfully leaks a 256-bit EdDSA key from libgcrypt (used in e.g. GPG) with a
98% success rate after just a single observation of signing operation on a co-resident hyperthread and just 17 seconds of analysis time."

"Add support for simple one-off internal rewrites.

For example:

location match "/page/(%d+)/.*" {
request rewrite "/static/index.php?id=%1&$QUERY_STRING"
}

Requested by many."

Woot. The diff to disable SMT (aka Hyperthreading) just landed in #OpenBSD -current.

You can now disable SMT via a sysctl. The default is disabled.
