You already get emails if upgrades are available for your server, at least
if you correctly configured an email address during installation, or after
installation for the root at pam user in DC -> Users tab.

We provide the channels to get this information, even notice actively on new
updates available, on grave issues, which affect all, or most user we also
make additional posts over our various channels (e.g., the apt transport bug,
meltdown/spectre, ...).

So no, it wasn't unannounced, it's documented publicly in our changelog and
bugzilla, as Alwin mentioned, and if you configured the servers correctly
you got an email about pending updates.

Looking a our full stack as a complex Linux Distribution there are coming
multiple bugs (including security and logic flaws) to light per week,
depending on your setup, what specific technologies you use, and the
environment your servers are exposed (e.g., public internet, vs. contained
LAN) a lot of them may be possible server destroying if you include take-over
possibilities, or the fact that not all admins can trust  their VMs and CTs
running on their system, and simple logic flaws, be it in our own stack, or
an upstream component we use. 

Making a separate announcement would then be effectively a mirror of the
changelog (which is already there), as quite some package releases may
include a fix which is relevant for a certain set of setups. And there would
be many that one would do hard to read them all, and remember them all, also
the real big fish would then have a higher chance to go unnoticed. Easier to
just upgrade once packages are released, on which event you get already
notified about..

So while I understand your pain here, I'd rather have users update frequently,
as all updates are important, and us using the time to fix more bugs and add
features, than to write announcements for every update, which is indirectly
already available to read.
