Changes from 2.2.1 to 2.3.0: - Add --cache option to speed up file comparisons. - Use nanosecond precision for file times, if available. - Fix compilation issue on OpenBSD. - Other changes like fixing typos, wording, etc. Changes from 2.2.0 to 2.2.1: - Fix bug in code meant to skip over the current log file when --log option is given. - Updates to copyright notices in source code. Changes from 2.1.2 to 2.2.0: - Add --deferconfirmation option. - Check that files marked as duplicates haven't changed during program execution before deleting them. - Update documentation to indicate units for SIZE in command-line options. - Move some configuration settings to configure.ac file. Changes from 2.1.1 to 2.1.2: - Do not enter ncurses mode when --immediate option given. - Fix logging/memory corruption bug when using --log with --immediate. Changes from 2.1.0 to 2.1.1: - Break mtime ties using ctime when sorting by time. - Reduce number of calls to stat(), for speed. - Clear last command status when new command is entered. Changes from 2.0.0 to 2.1.0: - Rename cs command ("clear all selections") from cs to csel. - Rename igs command ("invert selections") from igs to isel. - Add "prune" command as synonym for DELETE key. - Clear selections after deleting files via prune/DELETE. - Fix dependency issues when fdupes is configured to not use ncurses. Changes from 1.6.1 to 2.0.0: - Add ncurses mode for interactive file deletion (plain mode still available via --plain or ./configure). - Add --minsize option. - Add --maxsize option. - Add --time option. - Add --order=ctime option. - Add --log option. - Use configure script for installation (Autotools/Automake). Changes from 1.6.0 to 1.6.1: - Fix 'invalid option' error for -I. [AL] Changes from 1.51 to 1.6.0: - Add --nohidden option. [MC] - Add --permissions option. [MV] - Add --order option. [SB] - Add --reverse option. [AL] - Add --immediate option. [AL] - Speed up file comparison. [SB, ST] - Fix bug where fdupes fails to consistently ignore hardlinks, depending on file processing order, when F_CONSIDERHARDLINKS flag is not set. [AL] - Fix bug in is_hardlink(): Proper traversal of duplicates is done via dupe->duplicates, not via dupe->next. [AL] - Revise md5.c to compile under OSX. [TH] - Remove EXTERNAL_MD5 configuration option. [ID] - Various other changes (see git log). Changes from 1.50 to 1.51 - Added support for 64-bit file offsets on 32-bit systems. - Using tty for interactive input instead of regular stdin. This is to allow feeding filenames via stdin in future versions of fdupes without breaking interactive deletion feature. - Fixed some typos in --help. - Turned C++ style comments into C style comments. Changes from 1.40 to 1.50-PR2 - Fixed memory leak. [JB] - Added "--summarize" option. [AL] - Added "--recurse:" selective recursion option. [AL] - Added "--noprompt" option for totally automated deletion of duplicate files. - Now sorts duplicates (old to new) for consistent order when listing or deleteing duplicate files. - Now tests for early matching of files, which should help speed up the matching process when large files are involved. - Added warning whenever a file cannot be deleted. [CHL, AL] - Fixed bug where some files would not be closed after failure. [AL] - Fixed bug where confirmmatch() function wouldn't always deal properly with zero-length files. [AL] - Fixed bug where progress indicator would not be cleared when no files were found. [AL] - Removed experimental red-black tree code (it was slower on my system than the default code). [AL] - Modified md5/md5.c to avoid compiler warning. [CHL] - Changes to fdupes.c for compilation under platforms where getopt_long is unavailable. [LR, AL] - Changes to help text for clarity. [AL] - Various changes and improvements to Makefile. [PB, AL] Changes from 1.31 to 1.40 - Added option to omit the first file in each group of matches. [LM, AL] - Added escaping of filenames containing spaces when sameline option is specified. [AL] - Changed version indicator format from "fdupes version X.Y" to the simpler "fdupes X.Y". [AL] - Changed ordering of options appearing in the help text (--help), manpage, and README file. [AL] Changes from 1.30 to 1.31 - Added interactive option to preserve all files during delete procedure (something similar was already in place, but now it's official). [AL] - Updated delete procedure prompt format. [AL] - Cosmetic code changes. [AL] Changes from 1.20 to 1.30 - Added size option to display size of duplicates. [LB, AL] - Added missing typecast for proper compilation under g++. [LB] - Better handling of errors occurring during retrieval of a file's signature. [KK, AL] - No longer displays an error message when specified directories contain no files. [AL] - Added red-black tree structure (experimental compile-time option, disabled by default). [AL] Changes from 1.12 to 1.20 - Fixed bug where program would crash when files being scanned were named pipes or sockets. [FD] - Fix against security risk resulting from the use of a temporary file to store md5sum output. [FD, AL] - Using an external md5sum program is now optional. Started using L. Peter Deutsh's MD5 library instead. [FD, AL] - Added hardlinks option to distinguish between hard links and actual duplicate files. [FD, AL] - Added noempty option to exclude zero-length files from consideration [AL] Changes from 1.11 to 1.12 - Improved handling of extremely long input on preserve prompt (delete option). [SSD, AL] Changes from 1.1 to 1.11 - Started checking file sizes before signatures for better performance. [AB, AL] - Added fdupes manpage. [AB, AL] Changes from 1.0 to 1.1 - Added delete option for semi-automatic deletion of duplicate files. [AL]
