To create a license that will work only up to a specific date, you can use dates for major and minor version numbers as an alternative to specifying software release numbers.

Since LM-X requires by default that the version in the license file be greater than or equal to the number specified in the application, the license file will determine how long users can continue to use new updates of the software. If a software version has a date newer than the license, that version of the software will not work without an updated license.

To use dates for the version numbers, set the major version number to yyyy and the minor number to mmdd. For example, you could encode a license file to work until 2010.1001 (October 1, 2010), and set the version number in the application to the current compile date. In the future, when you create a new release with a date later (greater) than the license file date, say 2010.1201, that new version will require a new license file.
