+## [1.0.0] - 2021-03-17
+
+This release of GOCART is aimed at moving GOCART from GEOSchem_GridComp to its own repository. At the moment the only code here that is verified as correct is the "GOCART Legacy" code which is code that came from GEOSchem_GridComp v1.4.3.
+
+To use this release, you need to use GEOSchem_GridComp v1.4.4 which has the changes necessary to move GOCART Legacy to this separate repository.
+
+Identical in code to v1.0.0-beta.1
  
+## [1.0.0-beta.1] - 2021-03-01
