Here is 0.3.3. The major new feature is the optimised gzip compressor, which I described previously. This, implemented by the new -z option, is the recommended way of distributing files that are not already compressed.

I have also added the -k option, for keeping the zsync file on your local computer. This is useful if you ujst want to run zsync from a cron job, and have it download only when there is something newer on the server. Also new is the -e option, which causes zsyncmake to abort it it would not give the client an exact copy of the target file; and -C to disable the recompression support (which restores the 0.3.1 and earlier behaviour — sorry about that unannounced usage change in the previous version.

Apart from that, there are some bug fixes, for crashes that could occur in unusual cases. As usual, you can get the latest version from the download page. I am increasinly happy with the way zsync is working, and assuming the latest changes all settle down well, I am thinking of declaring a beta (instead of alpha) quality release. So I am interested for feedback on how people are getting on with it.
