 ### New features
 
+* Texar Tensorflow now imported by `import texar.tf as tx`. ([#197](https://github.com/asyml/texar/pull/197))
+* Add pretrained modules \[[docs](https://texar.readthedocs.io/en/latest/code/modules.html#pre-trained)\], e.g., BERT, XLNet, etc. ([#206](https://github.com/asyml/texar/pull/206))
+* Add new tensor shape related utils, e.g., [reduce_with_weights](https://texar.readthedocs.io/en/latest/code/utils.html#reduce-with-weights), [varlength\_\*](https://texar.readthedocs.io/en/latest/code/utils.html#varlength-concat). ([#201](https://github.com/asyml/texar/pull/201)) 
+
 ### Feature improvements
 
 ### Fixes
 
 * Fix docstring of connector `_mlp_transform`. ([#192](https://github.com/asyml/texar/pull/192))
+* Fix `dynamic_decode` out-of-range error when max-decoding-length is reached. ([#208](https://github.com/asyml/texar/pull/208))

 * The model will first be pre-trained for a few epochs (specified in `config.py`). During pre-training, the `Encoder-Decoder` part is trained as an autoencoder, while the `Classifier` part is trained with the classification labels.
 * Full-training is then performed for another few epochs. During full-training, the `Classifier` part is fixed, and the `Encoder-Decoder` part is trained to fit the classifier, along with continuing to minimize the autoencoding loss.
