Release Notes: xz was added as a supported compressed filetype. Diff of files with no trailing newline is now correct counted. Several portability fixes were made.
Release Notes: Compressed data is detected in standard input. The pack and lzma compression types were added. Perforce-style diffs are handled.
Release Notes: Modified to work with patch ".rej" files.
Release Notes: The "-S", "-D", and "-m" options were added to provide a way to show the amount of difference relative to the total sizes of the files. The "-q" option was added to suppress the message for empty files.
Release Notes: A "-b" option for ignoring binary file differences was implemented.
Release Notes: This release adds a check to ensure that unified diffs embedded in another file (such as email) do not count text past the last chunk of the diff.
Release Notes: A bugfix to avoid modifying data that is being used by tsearch() for ordering the binary tree.
Release Notes: This release will not ignore pathnames in /tmp/, since some tools create usable pathnames for both old/new files there (Debian #376086). It adds a configure check for compress, gzip, and bzip2 programs that may be used to decompress files.
Release Notes: New options include -l to list the changed files only, -r to round the histogram data, and -t to output comma separated values. I/O on Linux was improved. Searching of long sorted lists was improved. Configuration with Intel compilers was fixed.
Release Notes: This release changes the order of merging and prefix-stripping so that stripping all prefixes, e.g. with -p9, will be sorted as expected. A reference to freed memory after merging found with Valgrind (from 1.37) has been fixed.
