 Change Log
 ==========
 
+Release 2.8 - 6/22/2022
+-----------------------
+
+Neural Architecture Search
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* Align user experience of one-shot NAS with multi-trial NAS, i.e., users can use one-shot NAS by specifying the corresponding strategy (`doc <https://nni.readthedocs.io/en/v2.8/nas/exploration_strategy.html#one-shot-strategy>`__)
+* Support multi-GPU training of one-shot NAS
+* *Preview* Support load/retrain the pre-searched model of some search spaces, i.e., 18 models in 4 different search spaces (`doc <https://github.com/microsoft/nni/tree/v2.8/nni/retiarii/hub>`__)
+* Support AutoFormer search space in search space hub, thanks our collaborators @nbl97 and @penghouwen
+* One-shot NAS supports the NAS API ``repeat`` and ``cell``
+* Refactor of RetiariiExperiment to share the common implementation with HPO experiment
+* CGO supports pytorch-lightning 1.6
+
+Model Compression
+^^^^^^^^^^^^^^^^^
+
+* *Preview* Refactor and improvement of automatic model compress with a new ``CompressionExperiment``
+* Support customizating module replacement function for unsupported modules in model speedup (`doc <https://nni.readthedocs.io/en/v2.8/reference/compression/pruning_speedup.html#nni.compression.pytorch.speedup.ModelSpeedup>`__)
+* Support the module replacement function for some user mentioned modules
+* Support output_padding for convtranspose2d in model speedup, thanks external contributor @haoshuai-orka
+
+Hyper-Parameter Optimization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* Make ``config.tuner.name`` case insensitive
+* Allow writing configurations of advisor in tuner format, i.e., aligning the configuration of advisor and tuner
+
+Experiment
+^^^^^^^^^^
+
+* Support launching multiple HPO experiments in one process
+* Internal refactors and improvements
+
+  * Refactor of the logging mechanism in NNI
+  * Refactor of NNI manager globals for flexible and high extensibility
+  * Migrate dispatcher IPC to WebSocket
+  * Decouple lock stuffs from experiments manager logic
+  * Use launcher's sys.executable to detect Python interpreter
+
+WebUI
+^^^^^
+
+* Improve user experience of trial ordering in the overview page
+* Fix the update issue in the trial detail page
+
+Documentation
+^^^^^^^^^^^^^
+
+* A new translation framework for document
+* Add a new quantization demo (`doc <https://nni.readthedocs.io/en/v2.8/tutorials/quantization_quick_start_mnist.html>`__)
+
+Notable Bugfixes
+^^^^^^^^^^^^^^^^
+
+* Fix TPE import issue for old metrics
+* Fix the issue in TPE nested search space
+* Support ``RecursiveScriptModule`` in speedup
+* Fix the issue of failed "implicit type cast" in merge_parameter()
+
