Dates are in YYYY-MM-DD format.

v0.2.0 (2022-09-09)

Fixed bug in infer_engine.py (low accuracy due to indentation error).
Added Inception-v3 support: code and results.
Fixed User Guide links (they were the internal links, not public ones).
Fixed bug in examples/mobilenet/test_qdq_node_placement.py (we implemented a more general get_tfkeras_model for Keras models QAT workflows, but missed that change in the MobileNet test script).

Added note for Conv2DTranspose support in the main README file.
Improved generalization of residual branch detection for QDQ node placement.
