 # Changelog
 All notable changes to this project will be documented in this file. If you make a notable change to the project, please add a line describing the change to the "unreleased" section. The maintainers will make an effort to keep the [Github Releases](https://github.com/NREL/OpenOA/releases) page up to date with this changelog. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
+## Unreleased - TBD
+
+- Updates the Anaconda recommendation to alert users to the fact that Anaconda is no longer
+technically free, and so commercial users should consider Miniforge or Miniconda installations.
+
+## v3.1.2 2024-05-24
+
+- Updates the GitHub Actions workflows to use the latest versions of their workflow dependencies.
+- Changes a reference from the old `MonteCarloAEP._hours_in_res` to the new `MonteCarloAEP.resample_hours`.
+- Adds a step to filling in gaps in a time series that checks to see if there were any missing data,
+which helps avoid Pandas warnings.
+
 ## v3.1.1 - 2024-04-05
