On behalf of AVPreserve:

Version 0.3 of Fixity, the free fixity monitoring tool developed by
AVPreserve, has been officially released for download on AVPreserve's Tools
page <http://www.avpreserve.com/avpsresources/tools/> and via
GitHub<https://github.com/avpreserve/fixity>.
Fixity creates a manifest of files stored in directories identified by the
user, documenting file names, locations, and checksums. The user can then
schedule regular reviews of the directories to monitor for any changes to
files that may point to data corruption or loss. Fixity is ideal for
monitoring of files in long term storage, complimenting tools such as
Bagger and the BagIt specification that can be used to check fixity at
points of transition.

This release is a major update, addressing a number of issues related to
scheduling, running the utility while a laptop is on battery power,
compatibility with both 32-bit and 64-bit systems, and some user interface
revisions. A Mac version should be released in the coming weeks. Download
the new version of Fixity at http://www.avpreserve.com/avpsresources/tools/ and
keep providing your feedback so AVPreserve can continue to improve the tool.
