Pickle loading hardened; EUPE and TIPSv2 encoders added

July 10, 2026

• Improve optimizer torch.compile and tensor learning-rate support.
• Extend NaFlexViT patch-layout (for NaFlex-CLAP), and forward_intermediates (NaFlex dict input) support.
• Harden pickle loading and improve custom-label inference.
• Release 1.0.28

May 27, 2026

• Add model defs and pretrained weights for EUPE ViT (DINOv3-style) and ConvNeXt models. See the Efficient Universal Perception Encoder paper.
• Add TIPSv2 model defs and pretrained weights for (DINOv2-style) ViTs. See the TIPSv2 paper.
