Version 1.1.2.

Added adam update, changed gradient methdos to operate on gradient dicts instead of lists, added new container chain chain method, among other small changes.

This version was tested against: JAX 0.2.9 TensorFlow 2.4.1 PyTorch 1.7.1 MXNet 1.7.0 NumPy 1.19.5

However, Ivy 1.1.2 likely supports many previous and future backend versions, due to the stability of the core APIs for each backend framework.
