Download WinMerge 2.16.25 beta

A new development version of WinMerge has been released. WinMerge allows files or folders to be compared with each other: useful, for example, to see what has changed between different pieces of source code or to sift through the contents of log files. The program includes syntax highlighting and the application can create patch files based on the discovered differences. The following changes and improvements have been made in this release:
