6
7 - The --no-resume option has been removed.
8
9 - The gengetopt option parser has been replaced by the
10 [lopsub](http://people.tuebingen.mpg.de/maan/lopsub) library. Hence
11 lopsub must be installed to compile this package. Also help2man is
12 no longer required since lopsub has built-in roff support.
13
14 - "make install" will install the executable and the man page.
15
16 - In run mode, dss no longer exits successfully if another instance
17 is already running.
18
19 - New option --checksum to let rsync compute checksums occasionally.
20
21 - CFLAGS, CPPFLAGS and LDFLAGS can now be used to override the flags
22 of the build system.
23
24 - The dss logo is now created with ImageMagick rather than dia.
25
26 ------------------
27 0.1.7 (2017-04-17)
28 ------------------
29
30 - Documentation improvements.
31
32 - Improved error diagnostics.
33
34 - dss no longer refuses to run in daemon mode without a log file.
35
36 - Minor tweaks to the snapshot pruning algorithm.
37
38 - A fix for create mode when rsync exists unsuccessfully.
39
40 - NEWS and README have been converted to markdown format.
41
42 - We now compile with -Wunused-parameter and -Wshadow.
43
44 ------------------
45 0.1.6 (2015-08-05)
46 ------------------
47
48 - New option --min-complete to specify the minimal number of snapshots
49 to keep.
50
51 - Improved handling of rsync errors. The new --max-rsync-errors option
52 tells dss to terminate after the given number of rsync failures.
53
54 - New home page URL and email address.
55
56 - Reworked rsync restart logic, new --max-rsync-errors option.
57
58 - Avoidance of "Errors with program diagnostics" error from rsync.
59
60 - Improved signal handling.
61
62 ------------------
63 0.1.5 (2014-01-14)
64 ------------------
65
66 - snapshot recycling: outdated, redundant and orphaned snapshots are
67 reused as the basis for new snapshots.
68
69 - New subcommands: --kill, --reload.
70
71 - The semaphore-based locking system prevents to start multiple
72 instances of dss.
73
74 - When dss receives SIGHUP it now writes the internal state and the
75 configuration to the log file
76
77 - First steps to make the source code ANSI C conform (thanks to
78 Daniel Richard G).
79
80 - dss writes log messages to stderr rather than to the logfile unless
81 running in daemon mode.
82
83 - Default hooks work also on systems where "/bin/true" does not exist,
84 e.g. Mac OS.
85
86 ------------------
87 0.1.4 (2010-11-08)
88 ------------------
89 This version of dss contains some new features, many improvements of
90 existing features and several bug fixes.
91
92 Support for resuming snapshot creation after restart has been added
93 and snapshot removal is deferred until at least one current snapshot
94 exists. The internal handling of the various hooks has been simplified
95 and many error messages have been clarified. On SIGHUP, dss now writes
96 its configuration and internal state to the log file.
97
98 ------------------
99 0.1.3 (2009-06-06)
100 ------------------
101 You can now specify pre-rm/post-rm-hooks that are executed whenever
102 a snapshot is deleted. This release adds better compatibility with
103 rsync 3.0, and avoids busy loops when automatically restarting the
104 rsync process.
105
106 ------------------
107 0.1.2 (2009-03-05)
108 ------------------
109 This release includes the reason why a snapshot gets removed in the
110 log message. It will never remove the snapshot that is currently
111 being created. It will really pass the full path to the last complete
112 snapshot in the post_create_hook.
113
114 ------------------
115 0.1.1 (2008-11-13)
116 ------------------
117 This release prevents busy loops on rsync exit code 13. It ignores
118 any snapshot directory with creation time >= completion time. It
119 opens /dev/null for reading and writing when executing rsync. It shows
120 human readable snapshot creation duration when listing snapshots. It
121 restarts the rsync process if it returned with exit code 13.
122
123 ------------------
124 0.1.0 (2008-10-10)
125 ------------------
126 Initial public release.
