32 <h3>Rsync 3.0.0pre5 available for release testing</h3>
34 <p><i style="color:#777777">November 8th, 2007</i>
36 <p>Rsync version 3.0.0pre5 is now available for release testing.
38 <p>The version number is getting such a large bump due to the addition of an
39 incremental recursion scan (which helps a lot with large transfers) and the
40 official arrival of several other new features, including ACL support, extended
41 attribute support, filename character-set conversion, etc.
43 <p>Please test it and send email to the rsync mailing list with any questions,

95 <h3>Rsync version 2.6.8 released</h3>
97 <p><i style="color:#777777">April 22th, 2006</i>
99 <p>Rsync version 2.6.8 has been released. This is a bug-fix release that
100 primarily addresses an exclude problem that affected the --relative option,
101 but also includes a security fix for the xattrs.diff patch (which is not an
102 official part of rsync, but some packagers include it in their release).
104 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.8-NEWS">release NEWS</a> for the
105 details of what changed since 2.6.7.
107 <h3>Rsync 2.6.7 released</h3>
109 <p><i style="color:#777777">March 11th, 2006</i>
111 <p>Rsync version 2.6.7 has been released. This release has both several new
112 features and the usual accompaniment of bug fixes.
114 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.7-NEWS">release NEWS</a> for the
115 details of what changed since 2.6.6.
117 <h3>Rsync 2.6.6 released</h3>
119 <p><i style="color:#777777">July 28th, 2005</i>
121 <p>Rsync version 2.6.6 has been released. This release is a bug-fix release
122 to handle a null-pointer bug that turned up in rsync's version of zlib
123 1.1.4 (this is not the recent zlib 1.2.2 security fix, which did not
124 affect rsync) and to squash a few other minor bugs. To deal with the
125 zlib issue, rsync has been upgraded to include zlib 1.2.3.
127 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.6-NEWS">release NEWS</a> for the
128 details of what changed since 2.6.5.
130 <h3>Rsync 2.6.5 released</h3>
132 <p><i style="color:#777777">June 1st, 2005</i>
134 <p>Rsync version 2.6.5 has been released. This release is primarily a bug-fix
135 release to squash some annoying problems that made it into the (feature-filled)
136 release of 2.6.4, plus a few minor enhancements.
138 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.5-NEWS">release NEWS</a> for the
139 details of what changed since 2.6.4.
141 <h3>Rsync 2.6.4 released</h3>
143 <p><i style="color:#777777">March 30th, 2005</i>
145 <p>Rsync version 2.6.4 has been released. This release combines quite a
146 few new features, some improved delete efficiency, and the usual array of

150 details of what changed since 2.6.3.
153 <h3>Rsync 2.6.3 released</h3>
155 <p><i style="color:#777777">September 30th, 2004</i>
157 <p>Rsync version 2.6.3 has been released. It contains several new features
158 and quite a few bug fixes.
160 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.3-NEWS">release NEWS</a> for the
161 details of what changed since 2.6.2.

165 <h3 style="color:red">August 2004 Security Advisory</h3>
167 <p><i style="color:#777777">August 12th, 2004</i>
169 <p>There is a path-sanitizing bug that affects daemon-mode in
170 rsync versions through version 2.6.2, but only if chroot is disabled. It
171 does NOT affect the normal send/receive filenames that specify what
172 files should be transferred (this is because these names happen to get
173 sanitized twice, and thus the second call removes any lingering leading
174 slash(es) that the first call left behind). It does affect certain
175 option paths that cause auxiliary files to be read or written.
177 <p>This bug was fixed in version 2.6.3 of rsync.
179 <p>One potential fix that doesn't require recompiling rsync is to set
180 "use chroot = true" for all the modules in the rsyncd.conf file.
183 <h3>Rsync 2.6.2 released</h3>
185 <p><i style="color:#777777">April 30th, 2004</i>
187 <p>Rsync version 2.6.2 has been released. It is a bugfix release that mainly
188 fixes <b>a bug with the --relative option (-R) in 2.6.1</b>
189 that could cause files to be transferred incorrectly. This only affected a
190 source right at the root of the filesystem, such as "/" or "/*" (if you
191 first "cd /" and then copy from ".", it would not tickle the bug).
193 <p>See the <a href="/ftp/rsync/old-versions/rsync-2.6.2-NEWS">release NEWS</a> for the
194 details of what else was fixed.
197 <h3>Rsync 2.6.1 released</h3>
199 <p><i style="color:#777777">April 26th, 2004</i>
201 <p>Rsync version 2.6.1 has been released. It is primarily a performance
202 release that requires less memory to run, makes fewer write calls to the socket
203 (lowering the system CPU time), does less string copying (lowering the user CPU
204 time), and also reduces the amount of data that is transmitted over the wire.
205 There have also been quite a few bug fixes. See the
206 <a href="/ftp/rsync/old-versions/rsync-2.6.1-NEWS">release NEWS</a> for the full
210 <a name="security_apr04"></a>
211 <h3 style="color:red">April 2004 Security Advisory</h3>
213 <p><i style="color:#777777">April 26th, 2004</i>
215 <p>There is a security problem in all versions prior to 2.6.1 that affects only
216 people running a read/write daemon WITHOUT using chroot. If the user privs
217 that such an rsync daemon is using is anything above "nobody", you are at risk
218 of someone crafting an attack that could write a file outside of the module's
219 "path" setting (where all its files should be stored). Please either enable
220 chroot or upgrade to 2.6.1. People not running a daemon, running a read-only
221 daemon, or running a chrooted daemon are totally unaffected.
224 <h3>One Cygwin hang-problem resolved</h3>
226 <p>The problem with rsync hanging at the end of the transfer on
227 <a href="http://www.cygwin.com/">Cygwin</a> had been previously traced to a
228 signal-handling bug in their compatibility DLL. This bug appears to now be
229 fixed in DLL version 1.5.7-1, and Cygwin users are reporting that upgrading the
230 DLL removes the hang-at-end-of-transfer problem for their existing rsync executable.
231 (Note that this doesn't solve a hang that some folks see in the middle of a
232 transfer -- using daemon mode instead of ssh can work around that one.)

236 <h3>Rsync 2.6.0 released</h3>
238 <p><i style="color:#777777">January 1st, 2004</i>
240 <P> Two important things to note in the new release:
244 <li>The default remote shell is now "ssh" unless you tell configure you want to
245 make something else the default.
247 <li>Some bug fixes in the include/exclude code, while making things work
248 properly, have resulted in some user-visible changes for certain wildcard
249 strings. Read the BUG FIXES section in the
250 <a href="/ftp/rsync/old-versions/rsync-2.6.0-NEWS">NEWS file</a> to see if
251 any of these changes apply to you.
252 (Most people should be unaffected.)
256 <p>One other item of note is that the oft-requested option "--files-from" is now
257 available. This option lets you specify a list of files to transfer, and can
258 be much more efficient than a recursive descent using include/exclude
259 statements (if you know in advance what files you want to transfer). The list
260 of files can come from either side of the connection, so it is possible for a
261 server to provide the file-list that lets someone grab a server-specified set of
262 files, for example. See the <a href="/ftp/rsync/rsync.html">rsync man page</a>
265 <p>For a full list of changes in version 2.6.0, see the
266 <a href="/ftp/rsync/old-versions/rsync-2.6.0-NEWS">release NEWS</a>.

269 <h3 style="color:red">December 2003 Security Advisory</h3>
271 <p><i style="color:#777777">December 4th, 2003</i>
273 <p>Rsync version 2.5.6 and earlier contains a heap overflow vulnerability that
274 could be used to remotely run arbitrary code, but this only affects the use of
275 rsync as an "rsync daemon" (where rsync handles incoming socket connections,
276 typically on port 873).
278 <p>This bug was fixed in rsync 2.5.7.
