Version 4.0.0 of Saturn and Titan has been released. The software is available for Linux and Windows, the OS X version can’t yet be released as the iMac used for development acquired a GPU fault after 5 years of use and it has yet to be replaced.
New version of Saturn, new splash window:
New icons:
I failed to update the user manual for version 3.0.0, the changes since 2.1.x are even greater than they were before so there is a new issue of the User Manual. The software and User Manual are available on the Download page, the main changes are listed on the Release Notes page, both page are found via the Software menu.


Typo: replace splah with splash
Thanks.
