Upgrading C# project, cannot find the changelog for the packages

Question

I am currently working on upgrading one C# project from .net5 to .net6, and as I have to upgrade all the packages, I need (?) to somehow see the changelog or such alike, to know if there are some deprecated or altered methods that would have to be refactored, but it seems impossible to find those documents, looks like they do not exist for minor packages.

I found the list of breaking changes .net5 to .net6, I also find a few of the packages and their changelogs, but for most of the packages, e.g.:

Microsoft.Extensions.Logging
Microsoft.Extensions.Configuration.Binder
Microsoft.Extensions.Hosting
Microsoft.AspNetCore.Mvc.NewtonsoftJson

the changes are nowhere to be found.

I am upgrading mostly from 5.0.0 to 6.0.0, and even though I understand that there is very little chance that the changes would be breaking, I would like to make sure it is so. So, the question: Is it possible to find the changes from 5.00 to 6.0.0 for those minor packages, or how should one go about updating them?

TIA
