Dollar signs in options under <option>services.postfix</option> are
|
|
passed verbatim to Postfix, which will interpret them as the beginning of
|
|
a parameter expression. This was already true for string-valued options
|
|
in the previous release, but not for list-valued options. If you need to
|
|
pass literal dollar signs through Postfix, double them.

The OpenSSH service no longer enables support for DSA keys by default,

which could cause a system lock out. Update your keys or, unfavorably,

re-enable DSA support manually.

DSA support was

<link xlink:href="https://www.openssh.com/legacy.html">deprecated in OpenSSH 7.0</link>,
|

due to it being too weak. To re-enable support, add

After updating the keys to be stronger, anyone still on a pre-17.03

version is safe to jump to 17.03, as vetted
