- The `yeahwm` package and `services.xserver.windowManager.yeahwm` module were removed due to the package being broken and unmaintained upstream.

- The `boot.readOnlyNixStore` has been removed. Control over bind mount options on `/nix/store` is now offered by the `boot.nixStoreMountOpts` option.
- The Postfix module has been updated and likely requires configuration changes:
- The `services.postfix.sslCert` and `sslKey` options were removed and you now need to configure
-[services.postfix.config.smtpd_tls_chain_files](#opt-services.postfix.config.smtpd_tls_chain_files) for server certificates,
-[services.postfix.config.smtp_tls_chain_files](#opt-services.postfix.config) for client certificates.
