+I've released binfmt-support 2.2.0.  These are the major changes since
+2.1.8:
+
+ * Remove support for the old procfs interface, which has been unused since
+   Linux 2.4.13 and which caused trouble in environments where we can't use
+   modprobe.  Thanks to Bastian Blank.
+ * Sort formats by name in the output of `update-binfmts --display`.
+ * Building binfmt-support now requires Autoconf >= 2.63.
+ * Add a new `--unimport` action, which is the inverse of `--import`.
+ * Don't enable formats on import or disable them on unimport unless
+   `/proc/sys/fs/binfmt_misc` is already mounted.  This avoids causing
+   cleanup problems in chroots.
+ * `--fix-binary yes` is incompatible with detectors.  Warn the user if they
+   try to use both at once.  Thanks to Stefan Agner.
+
+In the corresponding Debian upload (2.2.0-1), I've changed README.Debian to
+recommend using `update-binfmts --unimport <name>` in the prerm rather than
+a more complicated `update-binfmts --package <package> --remove <name>
+<path>` command.  I don't intend to push for existing packages to switch
+over to this before buster, though, since the stricter package relationships
+needed to arrange for a new enough version of binfmt-support to be present
+when the prerm runs would make the upgrade path more complicated, and it
+isn't an urgent change.
