ESA Form Changes 2018 to 2019?

I had an ESA review at the beginning of 2018. I used the Benefits and Work ESA Guide to help fill in the ESA50 at the time. It was very helpful and my review was successful so I'm very grateful for that help.

A year later, I now have another ESA review and wondered if anything significant has changed in the ESA50 form since 2018 or if any of the criteria for the mental health section has changed? I looked at the latest ESA50 form and didn't notice any differences. The latest B&W ESA guide seems the same apart from the wording of the recorded interview request letter. Am I missing something?

Thanks for your reply but it doesn't really answer my questions which are:,

1) Has the ESA50 form changed in any way since 2018?

2) Has the advice in the Benefits and Work ESA Guide changed since 2018?

I've looked at the ESA50 form and it appears the same. The B&W ESA Guide appears to have the same advice. I'm asking because it's been a year since I filled in the ESA50 form and I want to be sure that there have been no changes or other surprises due to changes in legislation or DWP rules. I don't trust the DWP nor the government because they have changed the benefit criteria and rules frequently. Thanks in advance for any advice.
