My list of patches so far for the SRU can be seen at this address:

  https://bugs.launchpad.net/ubuntu/jammy/+source/openssl

It's likely that the list will be frozen before the end of next weeek.

There's only one thing I'd like to also SRU and which is about removing
dead code that also unecessarily sources debconf in the postinst and
which tends to trigger the infamous bug with thousands of duplicates on
launchpad. Unfortunately I'm not sure I can do that without delaying
this SRU and I might have to leave it for a subsequent one.
