 Change Log
 ==========
 
+Release 2.6 - 1/18/2022
+-----------------------
+
+**NOTE**: NNI v2.6 is the last version that supports Python 3.6. From next release NNI will require Python 3.7+.
+
+Hyper-Parameter Optimization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Experiment
+""""""""""
+
+* The legacy experiment config format is now deprecated. `(doc of new config) <https://nni.readthedocs.io/en/v2.6/reference/experiment_config.html>`__
+
+  * If you are still using legacy format, nnictl will show equivalent new config on start. Please save it to replace the old one.
+
+* nnictl now uses ``nni.experiment.Experiment`` `APIs <https://nni.readthedocs.io/en/stable/Tutorial/HowToLaunchFromPython.html>`__ as backend. The output message of create, resume, and view commands have changed.
+* Added Kubeflow and Frameworkcontroller support to hybrid mode.  `(doc) <https://nni.readthedocs.io/en/v2.6/TrainingService/HybridMode.html`__
+* The hidden tuner manifest file has been updated. This should be transparent to users, but if you encounter issues like failed to find tuner, please try to remove ``~/.config/nni``.
+
+Algorithms
+""""""""""
+
+* Random tuner now supports classArgs ``seed``. `(doc) <https://nni.readthedocs.io/en/v2.6/Tuner/RandomTuner.html`__
+* TPE tuner is refactored: `(doc) <https://nni.readthedocs.io/en/v2.6/Tuner/TpeTuner.html`__
+
+  * Support classArgs ``seed``.
+  * Support classArgs ``tpe_args`` for expert users to customize algorithm behavior.
+  * Parallel optimization has been turned on by default. To turn it off set ``tpe_args.constant_liar_type`` to ``null`` (or ``None`` in Python).
+  * ``constant_liar_type`` has been moved into ``tpe_args``. If you are using it please update your config.
+
+* Grid search tuner now supports all search space types, including uniform, normal, and nested choice. `(doc) <https://nni.readthedocs.io/en/v2.6/Tuner/GridsearchTuner.html`__
+
+Neural Architecture Search
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* Enhancement to serialization utilities `(doc) <https://nni.readthedocs.io/en/v2.7/NAS/Serialization.html`__ and changes to recommended practice of customizing evaluators. `(doc) <https://nni.readthedocs.io/en/v2.6/NAS/QuickStart.html#pick-or-customize-a-model-evaluator`__
+* Support latency constraint on edge device for ProxylessNAS based on nn-Meter. `(doc) <https://github.com/microsoft/nni/blob/v2.6/docs/en_US/NAS/Proxylessnas.rst`__
+* Trial parameters are showed more friendly in Retiarii experiments.
+* Refactor NAS examples of ProxylessNAS and SPOS.
+
+Model Compression
+^^^^^^^^^^^^^^^^^
+
+* New Pruner Supported in Pruning V2
+
+  * Auto-Compress Pruner `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/v2_pruning_algo.html#auto-compress-pruner`__
+  * AMC Pruner `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/v2_pruning_algo.html#amc-pruner`__
+  * Movement Pruning Pruner `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/v2_pruning_algo.html#movement-pruner`__
+
+* Support ``nni.trace`` wrapped ``Optimizer`` in Pruning V2. In the case of not affecting the user experience as much as possible, trace the input parameters of the optimizer. `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/v2_pruning_algo.html`__
+* Optimize Taylor Pruner, APoZ Activation Pruner, Mean Activation Pruner in V2 memory usage.
+* Add more examples for Pruning V2.
+* Add document for pruning config list.  `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/v2_pruning_config_list.html`__
+* Parameter ``masks_file`` of ``ModelSpeedup`` now accepts `pathlib.Path` object. (Thanks to @dosemeion) `(doc) <https://nni.readthedocs.io/en/v2.6/Compression/ModelSpeedup.html#user-configuration-for-modelspeedup`__
+* Bug Fix
+
+  * Fix Slim Pruner in V2 not sparsify the BN weight.
+  * Fix Simulator Annealing Task Generator generates config ignoring 0 sparsity.
+
+Documentation
+^^^^^^^^^^^^^
+
+* Supported GitHub feature "Cite this repository".
+* Updated index page of readthedocs.
+* Updated Chinese documentation.
+
+  * From now on NNI only maintains translation for most import docs and ensures they are up to date.
+
+* Reorganized HPO tuners' doc.
+
+Bugfixes
+^^^^^^^^
+
+* Fixed a bug where numpy array is used as a truth value. (Thanks to @khituras)
+* Fixed a bug in updating search space.
+* Fixed a bug that HPO search space file does not support scientific notation and tab indent.
+
+  * For now NNI does not support mixing scientific notation and YAML features. We are waiting for PyYAML to update.
+
+* Fixed a bug that causes DARTS 2nd order to crash.
+* Fixed a bug that causes deep copy of mutation primitives (e.g., LayerChoice) to crash.
+* Removed blank at bottom in Web UI overview page.
+

 **NOTE**: NNI v2.6 is the last version that supports Python 3.6. From next release NNI will require Python 3.7+.

   * Support classArgs ``seed``.
   * Support classArgs ``tpe_args`` for expert users to customize algorithm behavior.
   * Parallel optimization has been turned on by default. To turn it off set ``tpe_args.constant_liar_type`` to ``null`` (or ``None`` in Python).
-  * ``constant_liar_type`` has been moved into ``tpe_args``. If you are using it please update your config.
+  * ``parallel_optimize`` and ``constant_liar_type`` has been removed. If you are using them please update your config to use ``tpe_args.constant_liar_type`` instead.
 
 * Grid search tuner now supports all search space types, including uniform, normal, and nested choice. `(doc) <https://nni.readthedocs.io/en/v2.6/Tuner/GridsearchTuner.html>`__
