 * ❗Updates after Oct 10, 2022 are available in 0.8.x pre-releases (`pip install --pre timm`) or cloning main❗
 * Stable releases are 0.6.x and available by normal pip install or clone from [0.6.x](https://github.com/rwightman/pytorch-image-models/tree/0.6.x) branch.
 
+### March 22, 2023
+* More weights pushed to HF hub along with multi-weight support, including: `regnet.py`, `rexnet.py`, `byobnet.py`, `resnetv2.py`, `swin_transformer.py`, `swin_transformer_v2.py`, `swin_transformer_v2_cr.py`
+* Swin Transformer models support feature extraction (NCHW feat maps for `swinv2_cr_*`, and NHWC for all others) and spatial embedding outputs.
+* FocalNet (from https://github.com/microsoft/FocalNet) models and weights added with significant refactoring, feature extraction, no fixed resolution / sizing constraint
+* RegNet weights increased with HF hub push, SWAG, SEER, and torchvision v2 weights. SEER is pretty poor wrt to performance for model size, but possibly useful.
+* More ImageNet-12k pretrained and 1k fine-tuned `timm` weights:
+  * `rexnetr_200.sw_in12k_ft_in1k` - 82.6 @ 224, 83.2 @ 288
+  * `rexnetr_300.sw_in12k_ft_in1k` - 84.0 @ 224, 84.5 @ 288
+  * `regnety_120.sw_in12k_ft_in1k` - 85.0 @ 224, 85.4 @ 288
+  * `regnety_160.lion_in12k_ft_in1k` - 85.6 @ 224, 86.0 @ 288
+  * `regnety_160.sw_in12k_ft_in1k` - 85.6 @ 224, 86.0 @ 288  (compare to SWAG PT + 1k FT this is same BUT much lower res, blows SEER FT away)
+* Model name deprecation + remapping functionality added (a milestone for bringing 0.8.x out of pre-release). Mappings being added...
+* Minor bug fixes and improvements.

 ### Feb 26, 2023
 * Add ConvNeXt-XXLarge CLIP pretrained image tower weights for fine-tune & features (fine-tuning TBD) -- see [model card](https://huggingface.co/laion/CLIP-convnext_xxlarge-laion2B-s34B-b82K-augreg-soup)
 * Update `convnext_xxlarge` default LayerNorm eps to 1e-5 (for CLIP weights, improved stability)
