Update announcements

[rws]

Please accompany every software update with an announcement somewhere.
Today I received an update and, since I couldn't find any info about it,
I'm still suspicious as to how this came up: I cannot rule out an intrusion.

Note I did not ask for a changelist, that would be a bonus.

Regards,
rws
