v1.1.2

Fixing an issue with fsdp when some parameters are frozen.

v1.1.1

Higher memory efficiency when using beta1=0

v1.1

Major changes: add an option to make the optimizer more memory-efficient by using a higher value of the new hyperparameter slice_p (default 1).
Minor changes: optimized memory with zero initialization, and slightly changed implementation that doesn't affect the optimizer's behavior.
