    if the SSID or username contained non-ASCII characters **and** the
    default Python text-file encoding was set to ASCII. The files are

+ - *partition* always sets *bigtime* option on XFS filesystems, if possible.
+   Requires sufficiently-recent xfsprogs. #1874
  - *preservefiles* was missing some necessary features, needed for it
    to replace the deprecated log-file-saving functionality in the *umount*
    module. (Thanks Erik and Joe for testing) #1851
