### Please confirm these before moving forward.

- [x] I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.

### Describe the new feature

As a power-user I want to be in full control. UniGetUI allows me to find any software that are out-of-date.
But what I'm missing is a **convenient way of knowing what the changelog is for those software** updates.
I want to know what I'm installing, before updating blindly. Maybe there are breaking changes or features removed.

I understand that per package manager, changelog or release notes are handled differently. And most of the time they are absent and only available on GitHub for example.

Still, it would be great if some centralized overview of changes/release-notes could be integrated into UniGetUI.

An example of an tool that allows me to see changes, is [Extension Update Reporter](https://github.com/ryu1kn/vscode-extension-update-reporter?tab=readme-ov-file) for VSCode extension. It will unpack the extension and search for the CHANGELOG.md file. If it finds this, it will extract the changes based on the versioning and show that. If there is no changelog included, but it detects that the homepage is on GitHub, it will just link to the releases page. You could go even further, and do an API call to GitHub to extract an release or check if the source contains a changelog file.
