+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+have been replaced by subcommands.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+ - The gengetopt option parser has been replaced by the
+ [lopsub](http://people.tuebingen.mpg.de/maan/lopsub) library. Hence
+ lopsub must be installed to compile this package. help2man is
+ no longer required since lopsub has built-in roff support.
+
+ - New subcommand "configtest" to check the command line options and
+ the configuration file for syntactic correctness.
+
+ - New option: --mountpoint. If this option is given, dss aborts if
+ no file system is mounted on the destination directory.
+
+ - New option --checksum to let rsync compute checksums occasionally.
+
+ - The kill subcommand gained the new --wait option which instructs dss
+ to wait until the signalled process has terminated.
+
+ - The --no-resume option has been removed.
+
+ - On exit, the run subcommand now waits for any previously spawned
+ rsync or rm processes to terminate.
+
+ - The ls subcommand now shows the age of incomplete snapshots rather
+ than 0:00.
+
+ - In run mode, dss no longer exits successfully if another instance
+ is already running.
+
+ - The command specified as the argument to --exit-hook is now subject
+ to word splitting. Previously, the string was executed as-is.
+
+ - Improved error diagnostics for the kill subcommand.
+
+ - For all subcommands other than "run", timestamps and function names
+ are omitted from the log output.
+
+ - "make install" will install the executable and the man page.
+
+ - CFLAGS, CPPFLAGS and LDFLAGS can now be used to override the flags
+ of the build system.
+
+ - Source code files are now annotated with the SPDX GPL-2.0 license
+ identifier.
+
+ - The dss logo is now created with ImageMagick rather than dia.
+
+------------------
+0.1.7 (2017-04-17)
+------------------
+
+ - Documentation improvements.
+
+ - Improved error diagnostics.
+
+ - dss no longer refuses to run in daemon mode without a log file.
+
+ - Minor tweaks to the snapshot pruning algorithm.
+
+ - A fix for create mode when rsync exists unsuccessfully.
+
+ - NEWS and README have been converted to markdown format.
+
+ - We now compile with -Wunused-parameter and -Wshadow.
