 ## v1.2
 
 ### New ways to compute per sample gradients
-We're glad to present Opacus v1.2, which contains some major updates to per sample gradient computation mechanisms 
+We're glad to present Opacus v1.2, which contains some major updates to per sample gradient computation mechanisms
 and includes all the good stuff from the recent PyTorch releases.
 * Functorch - per sample gradients for all
 * ExpandedWeights - yet another way to compute per sample gradients
-* See [Release notes](https://github.com/pytorch/opacus/releases/tag/v1.2.0) 
-  and [GradSampleModule README](https://github.com/pytorch/opacus/blob/main/opacus/grad_sample/README.md)

 ### Other improvements
 * Fix `utils.unfold2d` with non-symmetric pad/dilation/kernel_size/stride (#443)
 * Add support for "same" and "valid" padding for hooks-based grad sampler for convolution layers
