 ## Changes
 
-### 0.16.1 (in development)
+### 0.16.1
 
-Release Date: TBD
+Release Date: July 24, 2025
+
+This release includes various small changes and improvements, as well as one significant new feature: (almost) all AgentType subclasses can now construct HA-SSJs (for use with the sequence_jacobian toolkit) in standard infinite horizon problems for arbitrary shock variables and arbitrary model outputs. This capability is powered by a new simulation structure that uses YAML-based model files to define dynamics, which in turn can be used to automatically transform HARK's model solution representations (policy functions over continuous spaces) into the grid-based representation needed for efficient computation of the fake news algorithm. Don't worry, that all happens under the hood.
+
+See documentation notebooks in /examples/SequenceSpaceJacobians/ . The capabilities of our SSJ calculator will be expanded in the near future to include lifecycle models.
