[jerryzh168]

This issue is tracking the deprecation of the (1) configs (2) model checkpoints quantized with these configs.

What is deprecated:

1. We added VERSION 2 config in Add Float8Tensor #2463, and switched the default version to 2 in TBD, the VERSION 1 config is now deprecated, please use VERSION 2 config to quantize the model
2. the quantized checkpoints quantized with VERSION 1 config previously is deprecated as well, and we plan to remove the ability to load these checkpoints in March 2026 (9 months from now)

Timeline:
0.13.0: annouce deprecation
