+1.0.0 (2017-11-19)
+------------------
+After almost ten years of development, dss has finally reached version
+1.0.0. Many new features have been implemented for this release. The
+list below contains the user-visible changes since the previous
+0.1.7 release. For the complete changelog consult the git log.
+
+The biggest user-visible change is that the former modes of operation
+have been replaced by subcommands. For example, the former -R option
+to start dss in "run" mode corresponds to the "run" subcommand of
+version 1.0.0. Each subcommand has its own set of options. Global
+options and options for subcommands are split with the usual "--"
+separator. For example, to specify the global --loglevel option and
+the run-specific --daemon option, use dss --loglevel 2 -- run --daemon.
+
+Although the new version has different syntax rules, the on-disk
+snapshot format remains the same. No conversion is required to continue
+existing snapshot directories created with older dss versions.
+
+The 0.1.x series will still be maintained for a while as the "maint"
+branch of the git repository, but this branch will only receive
+bug fixes.
- The gengetopt option parser has been replaced by the
