396 Dollar signs in options under

398 Postfix, which will interpret them as the beginning of a

496 The propagation logic has been changed. The new logic, along
497 with new types of dependencies that go with, is thoroughly
498 documented in the "Specifying dependencies" section
499 of the "Standard Environment" chapter of the nixpkgs
500 manual. The old logic isn't but is easy to describe:
501 dependencies were propagated as the same type of dependency no
502 matter what. In practice, that means that many
503 <literal>propagatedNativeBuildInputs</literal> should instead
504 be <literal>propagatedBuildInputs</literal>. Thankfully, that
505 was and is the least used type of dependency. Also, it means
506 that some <literal>propagatedBuildInputs</literal> should
507 instead be <literal>depsTargetTargetPropagated</literal>.
508 Other types dependencies should be unaffected.

539 The merging of config options for

541 Previously, if other options in the Postfix module like
542 <literal>services.postfix.useSrs</literal> were set and the
543 user set config options that were also set by such options,
544 the resulting config wouldn't include all options that were
545 needed. They are now merged correctly. If config options need
546 to be overridden, <literal>lib.mkForce</literal> or
547 <literal>lib.mkOverride</literal> can be used.
