+* Version 0.5.4 w/ release to be pushed to pypi. It's been a while since last pypi update and riskier changes will be merged to main branch soon....
+* Add ConvNeXT models /w weights from official impl (https://github.com/facebookresearch/ConvNeXt), a few perf tweaks, compatible with timm features
+* Tried training a few small (~1.8-3M param) / mobile optimized models, a few are good so far, more on the way...
   * `mnasnet_small` - 65.6 top-1
-  * `lcnet_100` - 72.1 top-1
+  * `mobilenetv2_050` - 65.9
+  * `lcnet_100/075/050` - 72.1 / 68.8 / 63.1
+  * `semnasnet_075` - 73
   * `fbnetv3_b/d/g` - 79.1 / 79.7 / 82.0
 * TinyNet models added by [rsomani95](https://github.com/rsomani95)
 * LCNet added via MobileNetV3 architecture
