Is there a one-page doc to tell which function now changes to which in OpenSSL3?

[Pei JIA]

Actually, my question is quite general:
It looks a lot of functions in **OpenSSL1.1.1** is NOW deprecated in
**OpenSSL3** .

   - Is there a doc to tell which function in  **OpenSSL1.1.1** is NOW
   changed to which function in **OpenSSL3** ???
   - Or any documentation that provides a very simple code snippet to
   compare the implementation based on **OpenSSL1.1.1** and the implementation
   using **OpenSSL3** .



```console
