* Deal better with date boundaries on the store operation (closes: #17).
- Add <warn_midnite> value in <store> configuration
- Add warnMidnite field to the StoreConfig object
- Add warning in store process for crossing midnite boundary
- Change store --full to have more consistent behavior
- Update manual to document changes related to this bug
Version 2.4.2 23 Apr 2005

Version 2.4.1 22 Apr 2005
* Fix minor typos in user manual and source code documentation.

Version 2.4.0 02 Apr 2005
* Re-license manual under "GPL with clarifications" to satisfy DFSG.
* Rework our unmount solution again to try and fix observed problems.
- Sometimes, unmount seems to "work" but leaves things mounted.
- This might be because some file is not yet completely closed.
- We try to work around this by making repeated unmount attempts.
- This logic is now encapsulated in util.mount() and util.unmount().
- This solution should also be more portable to non-Linux systems.

* Added -V,--version option to cback script.
* Rewrote parts of Makefile to remove most Debian-specific rules.
* Changed Makefile and setup.py to get version info from release.py.
