+------------------
+1.0.1 (2019-11-08)
+------------------
+Several fixes and improvements have accumulated over the years,
+so here is a new release. There are also some new features:
+
+- Support for multiple source directories.
+
+- The prune subcommand has been tweaked to use the same algorithm as
+ the run subcommand to decide which snapshot should be pruned. The
+ prune subcommand also gained the new --disk-space option.
+
+- When dss runs in daemon mode, it no longer sets the umask to zero.
+
+- The logo has been replaced by a slightly smaller one in svg format.
+
+------------------
+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+have been replaced by subcommands.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+ - The gengetopt option parser has been replaced by the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.
+
+------------------
+0.1.6 (2015-08-05)
+------------------
+
+ - New option --min-complete to specify the minimal number of snapshots
+ to keep.
+
+ - Improved handling of rsync errors. The new --max-rsync-errors option
+ tells dss to terminate after the given number of rsync failures.
+
+ - New home page URL and email address.
+
+ - Reworked rsync restart logic, new --max-rsync-errors option.
+
+ - Avoidance of "Errors with program diagnostics" error from rsync.
+
+ - Improved signal handling.
+
+------------------
+0.1.5 (2014-01-14)
+------------------
+
+ - snapshot recycling: outdated, redundant and orphaned snapshots are
+ reused as the basis for new snapshots.
+
+ - New subcommands: --kill, --reload.
+
+ - The semaphore-based locking system prevents to start multiple
+ instances of dss.
+
+ - When dss receives SIGHUP it now writes the internal state and the
+ configuration to the log file
+
+ - First steps to make the source code ANSI C conform (thanks to
+ Daniel Richard G).
+
+ - dss writes log messages to stderr rather than to the logfile unless
+ running in daemon mode.
+
+ - Default hooks work also on systems where "/bin/true" does not exist,
+ e.g. Mac OS.
+
+------------------
0.1.4 (2010-11-08)
-~~~~~~~~~~~~~~~~~~
+------------------
This version of dss contains some new features, many improvements of
existing features and several bug fixes.
and many error messages have been clarified. On SIGHUP, dss now writes
its configuration and internal state to the log file.
+------------------
0.1.3 (2009-06-06)
-~~~~~~~~~~~~~~~~~~
+------------------
You can now specify pre-rm/post-rm-hooks that are executed whenever
a snapshot is deleted. This release adds better compatibility with
rsync 3.0, and avoids busy loops when automatically restarting the
rsync process.
+------------------
0.1.2 (2009-03-05)
-~~~~~~~~~~~~~~~~~~
+------------------
This release includes the reason why a snapshot gets removed in the
log message. It will never remove the snapshot that is currently
being created. It will really pass the full path to the last complete
snapshot in the post_create_hook.
+------------------
0.1.1 (2008-11-13)
-~~~~~~~~~~~~~~~~~~
+------------------
This release prevents busy loops on rsync exit code 13. It ignores
-any snapshot directory with creation time > completion time. It
+any snapshot directory with creation time >= completion time. It
opens /dev/null for reading and writing when executing rsync. It shows
human readable snapshot creation duration when listing snapshots. It
restarts the rsync process if it returned with exit code 13.
+------------------
0.1.0 (2008-10-10)
-~~~~~~~~~~~~~~~~~~
+------------------
Initial public release.
