These are the release notes for the soon to be released rdup 1.1.0.

This is the first release of the new rdup branch, version 1.1.0.

Why this new branch?

I (and because of user requests) wanted to implement some extra features which needed (extensive) code modifications. I did not want to mess with the current stable release, hence a 1.1.x branch. However 1.1.x will obsolete 1.0.x soonish.

What is the difference with 1.0.x? (aka new features)

1. there is now only one default output format which always includes the files' contents;
2. the rdup output is now more comparable with the tar archive format, with the big difference of being able to delete files.
3. the new output includes: user- and groupnames and the modification timestamp of the file. They can now be correctly set on remote systems. (I.e the uid 'bert' stays 'bert' even if the remote side using a different uid numbers for 'bert');
4. more efficient, files are only read once. In rdup 1.0.x both rdup and rdup-tr read files, in 1.1.x only rdup reads files.

With this change the following new features were added

• rdup now has a -a switch: restore a-time when reading files;
• rdup-up now sets the m-time on files it creates, this is the default;
• rdup-up sets the user- and groupname more correct, see point 3. above;
• rdup-tr can now be run on remote systems, because it receives the files' content on standard input.

This work led to the following changes

• rdup has gotten the -P flag from rdup-up. This also makes the -a flag work even if you pipe the files' through external programs: they are only read once from disk;
• rdup-tr only processes from stdin to stdout;
• rdup-up only processes stdin;
• much more tests are added to the test suite (make check);
• code cleanups.

Some future work will of course remain, but I'm happy with how things turned out. A proper release will happen this week.

Those interested may check out the latest git code and play with that.
