 NEWS for rsync 3.0.0 (UNRELEASED)
 Protocol: 30 (changed)
 Changes since 2.6.9:

   BUG FIXES:

     - Fixed the output of -ii when combined with one of the --*-dest options:
       it now itemizes all the items, not just the changed ones.

     - Made the output of all file types consistent when using a --*-dest
       option.  Prior versions used to output too many creation events for
       matching items.

     - The code that waits for a child pid now handles being interrupted by a
       signal.  This fixes a problem with the pre-xfer exec function not being
       able to get the exit status from the script.

     - A negated filter rule now sends the negation option when sending the
       filter rules.

     - Fixed a problem with the --out-format (aka --log-format) option:  it
       would output superfluous directory information for a non-daemon rsync.

     - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
       files (which includes local copies).  Version 2.6.9 would complete the
       copy, but exit with an error when the receiver output its memory stats.

     - If --password-file is used on a non-daemon transfer, rsync now complains
       and exits.  This should help users figure out that they can't use this
       option to control a remote shell's password prompt.

     - Make sure that directory permissions of a newly-created destination
       directory are handled right when --perms is left off.

     - Improved --hard-link so that more corner cases are handled correctly
       when combined with options such as --link-dest and/or --ignore-existing.

   ENHANCEMENTS:

     - A new incremental-recursion algorithm is now used when rsync is talking
       to another 3.0.0 version.  This starts the transfer going more quickly
       (before all the files have been found), and requires much less memory.
       See the --recursive option in the manpage for some restrictions.

     - The default --delete algorithm is now --delete-during when talking to a
       3.x rsync.  This is a faster scan than using --delete-before (which is
       the default when talking to older rsync versions), and is compatible with
       the new incremental recursion mode.

     - Added the --delete-delay option, which is a more efficient way to delete
       files at the end of the transfer without needing a separate delete pass.

     - Added the --acls (-A) option to preserve Access Control Lists.  This is
       an improved version of the prior patch that was available.  (If you need
       to have backward compatibility with old, patched versions, the new
       acls.diff patch that will add that.)

     - Added the --xattrs (-X) option to preserver extended attributes.  This is
       an improved version of the prior patch that was available.  (If you need
       to have backward compatibility with old, patched versions, the new
       xattrs.diff patch that will add that.)

     - Added the --fake-super option that allows a non-super user to preserve
       all attributes of a file by using a special extended-attribute idiom.
       There is also an analogous "fake super" option for an rsync daemon.

     - Added the --iconv option, which allows rsync to convert filenames from
       one character-set to another during the transfer.  The default is to make
       this feature available as long as your system has iconv_open().  If
       compilation fails, specify --disable-iconv to configure and rebuild.  If
       you want rsync to perform character-set conversions by default, you can
       specify --enable-iconv=CONVERT_STRING with the default value for the
       --iconv option that you wish to use.  For example, --enable-iconv=. is a
       good choice.  See the rsync man page for an explanation of the --iconv
       option's settings.

     - Added the --skip-compress=LIST option to override of the default list of
       file suffixes that will not be compressed when using --compress.

     - The --max-delete option now outputs a warning if it skipped any file
       deletions, including a count of how many deletions were skipped.  (Older
       versions just silently stopped deleting things.)

     - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
       about any files that it wants to delete without deleting anything.  If
       you're not sure what version the client is, you can use the less-obvious
       --max-delete=-1, as old and new versions will both treat that as the
       same request (though older versions don't warn).

     - The --hard-link option now uses less memory on both the sending and
       receiving side for all protocol versions.  For protocol 30, the use of a
       hashtable on the sending side allows us to more efficiently convey to the
       receiver what files are linked together.  This reduces the amount of data
       sent over the socket by a considerable margin (rather than adding more
       data), and limits the in-memory storage of the device+inode information
       to just the sending side for the new protocol 30, or to the receiving
       side when speaking an older protocol (note that older rsync versions kept
       the device+inode information on both sides).

     - A lot more --no-OPTION override options are now supported.

   INTERNAL:

     - The file-list sorting algorithm now uses a sort that keeps any same-
       named items in the same order as they were specified.  This allows
       rsync to always ensure that the first of the duplicates is the one
       that will be included in the copy.  The new sort was also faster
       than the glibc version of qsort() and mergesort() in my testing.

     - Rsync now supports the transfer of 64-bit timestamps (time_t values).

     - Fixed a build problem with older (2.x) versions of gcc.

     - Added some isType() functions that make dealing with signed characters
       easier without forcing variables via casts.

     - Upgraded the included popt version to 1.10.2 and improved its use of
       string-handling functions.

     - Added missing prototypes for compatibility functions from the lib dir.

     - Configure determines if iconv() has a const arg, allowing us to avoid a
       compiler warning.

     - Made the sending of some numbers more efficient for protocol 30.

     - Make sure that a daemon process doesn't mind if the client was weird and
       omitted the --server option.

     - Improved the use of "const" on pointers.

     - Improved J.W.'s pool_alloc routines to add a way of freeing older
       sections of a pool's memory.

   DEVELOPER RELATED:

     - Rsync is now licensed under the GPLv3 or later.

     - Rsync now has a way of handling protocol-version changes during the
       development of a new protocol version.  This exchange of sub-version
       info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking
       in older versions (which would be the case if every minor change made
       to the protocol in CVS incremented the main PROTOCOL_VERSION value).
