-## [Unreleased]
+## [0.15.1-preview] - 2020-03-30
+### Bug Fixes
+ - Raise the wall in CrawlerStatic scene to prevent Agent from falling off. (#3650)
+ - Fixed an issue where specifying `vis_encode_type` was required only for SAC. (#3677)
+ - Fixed the reported entropy values for continuous actions (#3684)
+ - Fixed an issue where switching models using `SetModel()` during training would use an excessive amount of memory. (#3664)
+ - Environment subprocesses now close immediately on timeout or wrong API version. (#3679)
+ - Fixed an issue in the gym wrapper that would raise an exception if an Agent called EndEpisode multiple times in the same step. (#3700)
+ - Fixed an issue where logging output was not visible; logging levels are now set consistently (#3703).
+
+
+## [0.15.0-preview] - 2020-03-18
 ### Major Changes
  - The `--load` and `--train` command-line flags have been deprecated. Training now happens by default, and
  use `--resume` to resume training instead. (#3705)
