Version 6.0.1 of cwRsync client/server installers contain the latest available Cygwin/GNU tools. OpenSSH binaries are also updated to version 8.2p with LibreSSL 3.0.2.

Version 6.0.0 is a cwRsync server focused release, in where we have upgraded Cygwin DLL to the latest 3.x version.  Thanks to major changes in Cygwin, cwRsync server doesn't need a dedicated service account any longer and is run by the local system account. A direct upgrade to version 6.0.0 is not supported for the server: You need to uninstall it and install the new one as a fresh installation.

Version 5.7.4 is a cwRsync client focused release, in where we have upgraded OpenSSH to 8.0p, LibreSSL to 2.9.1 and Cygwin DLL to 2.11.1. Installers with 32-bit binaries are not provided any longer as a part of our product. Our installers require now entering an Itefix key during the installation. Please contact us if you don't have such a key.

Version 5.7.3 of cwRsync client/server installers come with updated ssh (OpenSSh 7.9p, cygwin and other tools. The server installer offers now a 36-char complex password consisting of upper- and lowercase letters and digits. You need to provide of your own password if that complexity doesn't meet your system requirements.
