LIS software releases

The full suite of LIS software is now available on GitHub:

GitHub LIS Framework Page

For more information, please see this announcement.

Please see the Releases page both for a summary of improvements in the most recent versions and to download a tarball of the code, which is subject to agreeing to the NASA Open Source Agreement (NOSA).

To learn how to download and use the latest development LIS code repository via our GitHub page, please review the Working with GitHub documentation on getting familiar with GitHub and accessing LIS from there.

Operational and other users who need stable and fully supported code are encouraged to use one of the latest formal numbered releases. Developmental users, including those who may wish to submit new features and/or bug fixes back into the repository, are encouraged to follow the instructions on Working with Github.

Want to receive the latest in breaking news and other important announcements about LIS? Please join the LIS mailing list. (No worries, it's low volume.)

The last available public release of LIS is version 7.3.1 or 'LISF Public 7.3.1 Release' (released on 26 March 2021).

Releases of LIS prior to version 7.1rp1 are released as U.S. government-purpose only. These releases of the LIS software are subject to NASA legal review and require that users sign a Software Usage Agreement (SUA). The point of contact for discussing and processing requests for the older LIS software is Sujay Kumar.

Please also note that LIS 4 and LIS 5 are no longer supported, and LIS 6 has limited support.
