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.
Contents
Release schedule
Please see the GEOS-Chem Release Proposal outlining the procedure and schedule for releasing GEOS-Chem versions.
Merged and awaiting release
See the links below for items merged and awaiting release.
Patch version in development | Major version in development |
