The 2018A Gemini Observing Tool is now available for download. This update is required to access the Gemini Observing Databases.
The Installation Instructions are linked on the Observing Tool web page, and we recommend that everyone download their programs from the databases rather than import from saved XMLs.
Visit the Gemini Science Software Blog for a description of some of the improvements, and see the the Release Notes for a complete list of changes.
