* cvsup2cvsync, which is a utility to convert a CVSup(R) scanfile into
a cvsync counterpart, has been added. When the upstream server
is using CVSup and you want to redistribute the contents using CVSync,
this tool is your friend.
* Support poll() instead of select() if available (server/client).
* cvsync(1) now supports "refuse" file. Using the refuse file,
you can prevent files/directories in a collection from
adding/updating/removing on the client side.
0.22.0 has a serious compression bug. If you use old versions,
please upgrade to 0.23.0. If 0.23.0 detects the remote host is
0.22.0, it will forcibly fall back to no compression mode.
