2009-06-07 - v1.18.3:

• Fix python2.6 md5 and sha module deprecation warnings.

2008-06-22 - v1.18.2:

• Print help output to stdout under non-error conditions. (Requested by Simon Howard)
• Work around mmap file descriptor leak in Python 2.4.2.
• Support different module layout of BitTorrent 5.x.
• Fix "struct integer overflow masking is deprecated" warning. (Reported by jjacobs2)
• Add --private_torrent flag. (Requested by Anders Henke)
• Work around bug in Python (only manifests with 64-bit Python version >= 2.5) which causes checksums of files > 4GB to be incorrectly calculated (when using mmap, eg, when the progress meter is disabled or not shown.)

2005-02-04 - v1.18.1:

• Fix TypeError when using progress meter and checksumming stdin.
• Fix progress meter spew when checksumming special files(devices, named pipes, etc.)
• Sort list of checksum types in --help output.
• Make -t help (or -t with unknown type) print list of types, with descriptions.

2005-01-11 - v1.18:

• Added special hack for multi-file .torrents to automatically strip the first path component off if it doesn't exist. (Allows testing .torrent files within their dirs without having to manually do --strip=1)
• Added .torrent creation support.
• Fix testing torrents which contain large number of files giving "too many open files" errors.
• Fix failure of -n in renaming bad files when testing a torrent file on windows due to windows not allowing renaming a file that is open.
• Fix TypeError when using --progress=yes and not running under a tty and COLUMNS env var is set. (Reported by Steven Mueller)
• Work around mmap error on large files. (Reported by Sapheriel)
• Added sha1sum file support (-t sha1).

2004-07-10 - v1.17:

• Handle .torrent files that have the creation date encoded as a string.
• Handle .torrent files that specify the filename encoding.
• Fix exceptions when trying to print unicode filenames containing non-ascii characters.

• Make .torrent support try BitTornado module if BitTorrent isn't found.
• Fix --strippaths=0 handling of multiple leading slashes and of dos-style drive letters with forward slashes.
• Improve handling of " and , in filenames in CSV files. (CSV parsing still won't be 100% correct, but doing any better would basically require adding a dependancy on some external csv module..)
• Replace automagic buggy-quoting workaround with --unquote option, fixes --strippath handling of quoted filenames and avoids potential insanity with -n, -s, and quoted filenames.

2003-11-20 - v1.16:

• Optimize progress meter display when checking lots of small files.
• Add .torrent file support (requires BitTorrent.)

2003-08-23 - v1.15:

• Check that PAR2 files have FileDesc packets for every file listed in the Main packet.
• Cache file checksums in memory in case they are verified by multiple checksum files.
• -u now works correctly with deep checksum files.
• -u option will now show dir/* if no files in a dir were verified. (--list=unverified still lists each unverified file.)
• -uu can be used to force showing all unverified files.
• Fix handling of the [files...] arguments in recursive test mode.
• Add .p[0-9][0-9] (par1 recovery files) to the list of checksum file extensions to test automatically.
• Fix FutureWarning "%X of negative int ..." on Python 2.3.
• Add progress meter for file checksumming. (Can be toggled with the progress option.)

• Fix fixpaths option on windows.

2003-05-23 - v1.14:

• Support md5sum files with comments in them.

• Specifying -t in testmode without -f will cause cfv to only test files it finds if they are of the given type.

• Updated my email address. The old one should still forward for about a year, but you should switch to using the new one when contacting me.
• Support _cfvrc as an alternate name for .cfvrc.
• Add win32src zip and win32 installer exe (using NSIS and py2exe).

2002-12-18 - v1.13:

• Fix exception in test mode when specifying -t and -f with a non-existant file.
• Add support for sfvmd5 files generated by some windows software. (Just a SFV formatted file using md5 checksums rather than crc32.)
• Handle quoted paths and filenames in csv4 files.
• Add filename_type .cfvrc option to allow user overriding of what type of checksum file to create when -t isn't specified and -f is.
• Only print the md5sum "tested in textmode" warning once, and print a count at the end.

• Fix cfv -u -t blah -f foo.blah from reporting foo.blah as unverified.
• Make create mode also display seperate stats per checksum file.

• Fix exception on error creating/writing a checksum file. (Eg, in a readonly dir, or a full drive.)
• Accept files with weird line endings (eg \r\r\n).
• Add support for (JPEG Sheriff format) .crc files. (The dimensions column is only added if The Python Imaging Library is avialable.)
• Fix printing incorrect paths for subsequent files in recursive mode after encountering a directory that could not be accessed.

2002-04-08 - v1.11:

• Due to architectural changes, unicode requirements(for .par support), etc, cfv now requires python 1.6 or higher.
• Add test-only support for PAR files. (python 1.6 or 2.2 recommended for better performance.)
• Print first SFV comment line in testing from blah.sfv line. (usually shows creating sfv program/creation time.)
• Add --strippaths option. (Like patch's -p/--strip option.)
• Revamp --showpaths option parsing, and add relative mode. (Note, auto-relative is now the default, to get the old behaviour specify "showpaths auto-absolute" in your .cfvrc)
• Added cmdlineglob config option.
• Added -Q command line arg to show only status lines.
• Alternate method of setting verbose .cfvrc option (using command line verbosity option letter.)

2001-12-06 - v1.10:

• Fix file.close() exception on -C in empty dir.
• Add mmap support for faster checksumming when not using fchksum module.
• Add CFV_NOFCHKSUM and CFV_NOMMAP env vars. (Mostly for testing/debugging.)
• Handle files made by buggy programs that add quotes to filenames.

• Support bsd style md5 files (-t bsdmd5).
• Make test.py not attempt to verify against md5sum if it is not available (ie, on bsd). (reported by Hannu Liljemark)

• Accepts - to represent stdin for data source and/or stdout for destination of checksums.
• Added -VV option.
• Errors printed to stderr instead of stdout.
• Uses class instances instead of imp module for checksum types.
• If using fchksum module, you now need at least version 1.2 (due to stdin ability).

• Added ignore case option.
• Added fix paths option.
• Added handler for csv files with the dir seperate from the file name (-t csv4).
