 ## What's New
 
+## Nov 28, 2024
+* More optimizers
+  * Add MARS optimizer (https://arxiv.org/abs/2411.10438, https://github.com/AGI-Arena/MARS)
+  * Add LaProp optimizer (https://arxiv.org/abs/2002.04839, https://github.com/Z-T-WANG/LaProp-Optimizer)
+  * Add masking from 'Cautious Optimizers' (https://arxiv.org/abs/2411.16085, https://github.com/kyleliang919/C-Optim) to Adafactor, Adafactor Big Vision, AdamW (legacy), Adopt, Lamb, LaProp, Lion, NadamW, RMSPropTF, SGDW
+  * Cleanup some docstrings and type annotations re optimizers and factory
+* Add MobileNet-V4 Conv Medium models pretrained on in12k and fine-tuned in1k @ 384x384
