The <varname>hardware.amdHybridGraphics.disable</varname> option was removed for lack of a maintainer. If you still need this module, you may wish to include a copy of it from an older version of nixos in your imports.

The merging of config options for <varname>services.postfix.config</varname>
was buggy. Previously, if other options in the Postfix module like
<varname>services.postfix.useSrs</varname> were set and the user set config
options that were also set by such options, the resulting config wouldn't
include all options that were needed. They are now merged correctly. If
config options need to be overridden, <literal>lib.mkForce</literal> or
<literal>lib.mkOverride</literal> can be used.
