14 December 2009:

As of 12 November 2009 weather images and other weather-related metadata are no longer being transferred to the GSA and as a result will not be included in future PI data packages. Records of GSA download activity indicate that archive users rarely retrieve these files so the effort required to maintain this service will be applied to other archive activities.

2 June 2009: version 1.75 of the Gemini Science Archive is released.

New functionality includes:

• New access control management pages for Gemini Principal Investigators.
• New help pages describing PI access-control mechanisms.

11 February 2009: version 1.71 of the Gemini Science Archive is released.

New functionality includes:

• New Gemini Publication query form is now available.
• Bug fixes and interface improvements.

17 November 2008: version 1.70 of the Gemini Science Archive is released.

• Bug fixes and interface improvements.

24 April 2006: version 1.40 of the Gemini Science Archive is released.

New functionality includes:

• New standard queries for GNIRS, NIFS, bHROS, and Michelle.
• Archive users can now retrieve individual files immediately by clicking on the icon in the "Get File" column.
• New, individual System Verification (SV) datasets are now available through the GSA.
• E-transfer improvements now result in raw Gemini datasets being available to authorized archive users typically within 15 minutes of acquisition.
• New logging interface for Gemini Staff.
• Bug fixes and interface improvements.

25 January 2006: version 1.35 of the Gemini Science Archive is released.

New functionality includes:

• Addition of NIFS data to the GSA.
• Addition of bHROS data to the GSA.
• Addition of an Observing Log query form.
• Bug fixes and interface improvements.

17 October 2005: version 1.3 of the Gemini Science Archive is released.

25 May 2005: version 1.2 of the Gemini Science Archive is released.

New functionality includes:

• Availability of PI Electronic Distribution (version 1) that distributes raw science data and ancillary files (e.g. obslogs, weather images, etc). PIs are instructed via email on how to retrieve the distribution package once they are created by the GEMINI staff. Co-Investigators and other authorized users can access these distribution packages through the Gemini PI Access page .
• Links to Mask Definition Files (MDF) from the science page (where applicable).
• A new database server for improved reliability and query performance.
