4
5 - New option --min-complete to specify the minimal number of snapshots
6 to keep.

9 tells dss to terminate after the given number of rsync failures.
10
11 - New home page URL and email address.
12
13 - Reworked rsync restart logic, new --max-rsync-errors option.
14

18
19 ------------------
20 0.1.5 (2014-01-14)
21 ------------------
22
23 - snapshot recycling: outdated, redundant and orphaned snapshots are
24 reused as the basis for new snapshots.
25
26 - New subcommands: --kill, --reload.
27
28 - The semaphore-based locking system prevents to start multiple
29 instances of dss.
30
31 - When dss receives SIGHUP it now writes the internal state and the
32 configuration to the log file
33
34 - First steps to make the source code ANSI C conform (thanks to
35 Daniel Richard G).
36
37 - dss writes log messages to stderr rather than to the logfile unless
38 running in daemon mode.
39
40 - Default hooks work also on systems where "/bin/true" does not exist,
41 e.g. Mac OS.
42
43 0.1.4 (2010-11-08)
44 ~~~~~~~~~~~~~~~~~~
45 This version of dss contains some new features, many improvements of
46 existing features and several bug fixes.
47
48 Support for resuming snapshot creation after restart has been added
49 and snapshot removal is deferred until at least one current snapshot
50 exists. The internal handling of the various hooks has been simplified
51 and many error messages have been clarified. On SIGHUP, dss now writes
52 its configuration and internal state to the log file.
53
54 0.1.3 (2009-06-06)
55 ~~~~~~~~~~~~~~~~~~
56 You can now specify pre-rm/post-rm-hooks that are executed whenever
57 a snapshot is deleted. This release adds better compatibility with
58 rsync 3.0, and avoids busy loops when automatically restarting the
59 rsync process.
60
61 0.1.2 (2009-03-05)
62 ~~~~~~~~~~~~~~~~~~
63 This release includes the reason why a snapshot gets removed in the
64 log message. It will never remove the snapshot that is currently
65 being created. It will really pass the full path to the last complete
66 snapshot in the post_create_hook.
67
68 0.1.1 (2008-11-13)
69 ~~~~~~~~~~~~~~~~~~
70 This release prevents busy loops on rsync exit code 13. It ignores
71 any snapshot directory with creation time >= completion time. It
72 opens /dev/null for reading and writing when executing rsync. It shows
73 human readable snapshot creation duration when listing snapshots. It
74 restarts the rsync process if it returned with exit code 13.
75
76 0.1.0 (2008-10-10)
77 ~~~~~~~~~~~~~~~~~~
78 Initial public release.
