 ## What's New
 
+### Feb 29, 2020
+* New MobileNet-V3 Large weights trained from stratch with this code to 75.77% top-1
+* IMPORTANT CHANGE - default weight init changed for all MobilenetV3 / EfficientNet / related models
+  * overall results similar to a bit better training from scratch on a few smaller models tried
+  * performance early in training seems consistently improved but less difference by end
+  * set `fix_group_fanout=False` in `_init_weight_goog` fn if you need to reproducte past behaviour
+* Experimental LR noise feature added applies a random perturbation to LR each epoch in specified range of training
+
 ### Feb 18, 2020
 * Big refactor of model layers and addition of several attention mechanisms. Several additions motivated by 'Compounding the Performance Improvements...' (https://arxiv.org/abs/2001.06268):
   * Move layer/module impl into `layers` subfolder/module of `models` and organize in a more granular fashion
