+* Fix 'series' not appearing on UI when using `logger.report_table()` [ClearML GitHub issue #684](https://github.com/allegroai/clearml/issues/684)
+* Fix `Task.init()` docstring to include behavior when executing remotely [ClearML GitHub PR #737](https://github.com/allegroai/clearml/pull/737)

+  * Fix wait for jobs based on local/remote pool frequency
+  * Fix `UniformIntegerParameterRange.to_list()` ignores min value
+  * Fix pipeline component returning a list of length 1
+* Datasets
+  * Fix `Dataset.get()` does not respect `auto_create`
+  * Fix getting datasets fails with new ClearML Server v1.6
+  * Fix datasets can't be queried by project/name alone
+  * Fix adding child dataset to older parent dataset without stats
+* Fix error when connecting an input model
+* Fix deadlocks, including:
+  * Change thread Event/Lock to a process fork safe threading objects

+* Fix `StorageManager.list()` on a local Windows path
+* Fix model not created in the current project
+* Fix `keras_tuner_cifar` example raises DeprecationWarning and ValueError
