The SIESTA developers have decided to change the licensing conditions for the code. From now on, SIESTA will be released under the GPL open-source license.
In the past SIESTA had always been free for academic use, but re-distribution was not permitted. It is expected that the move to an open-source license will be beneficial for the SIESTA project and its large user community. On the one hand, the program will be able to incorporate functionality already existing in other GPL codes. On the other, the barrier for contributors will be lowered, as new developments will be more easily re-distributed.
Development and distribution of the program is now centralized at the Launchpad platform
Users can download tarballs of released versions, as well as clone the source branches of the appropriate series directly. Prospective contributors are encouraged to become familiar with the Launchpad workflow and to read the specific documentation that is being prepared for Siesta development.
The current stable series is ‘4.0’, which is in advanced betastage. Users are encouraged to download it and use it for production runs.
