On this page we list the current priorities for GEOS-Chem development.  This list was compiled by the user Working Groups at the last [http://acmg.seas.harvard.edu/geos/meetings/2013/index.html International GEOS-Chem Meeting (IGC6)] in May 2013 and has been continuously updated since based on code readiness and input from the Working Groups and the Steering Committee.

We also invite you to view our [https://trello.com/board/geos-chem-support-team/4fe36668fc79a1d3540ba80b GEOS-Chem Support Team project management board on Trello.com], which shows the current GCST workflow.

On this page we list the current priorities for GEOS-Chem development. This list is continuously updated based on code readiness and input from the [http://acmg.seas.harvard.edu/geos/geos_working_groups.html Working Groups] and the [http://acmg.seas.harvard.edu/geos/geos_steering_cmte.html Steering Committee]. For history of past releases see the [[GEOS-Chem_versions|GEOS-Chem Versions wiki page]].
  
== List of priorities as of May 2013 ==
+
== Release schedule ==
  
Items "Awaiting release" will be part of the next version release of GEOS-Chem and are actively being incorporated into the standard model and benchmarked. Other items are in different stages of readiness and will be included in future versions of the model.
+
Please see the [http://wiki.seas.harvard.edu/geos-chem/images/e/e1/GEOS-Chem_Release_Proposal.pdf GEOS-Chem Release Proposal] outlining the procedure and schedule for releasing GEOS-Chem versions.

On this page we list the current priorities for GEOS-Chem development. This list is continuously updated based on code readiness and input from the Working Groups and the Steering Committee. For history of past releases see the GEOS-Chem Versions wiki page.

Release schedule

Please see the GEOS-Chem Release Proposal outlining the procedure and schedule for releasing GEOS-Chem versions.
