 ## [Unreleased]
+## [0.2.1] - 2022-11-01
+### Fixed
+- Fixes a bug where storage constraints were not initialized in the `DispatchModel`.
+- Fixes the tolerances in the testing suite so that the tests pass. 
+Previously, a single test was failing due to (-1e-9 == 0 ± 1e-12). 
+This should pass, since 1e-9 is still close to zero.
+
 ## [0.2.0] - 2022-10-31
 ### Added
 - Adds the following Technology subclasses
