deprecated - Keeping up with standards, new releases and deprecations -

I want to know how the programmers move with a change in a package or library I usually go to the release notes How to maintain with standards and maintain good coding practices?
thanks

edit
"Maintaining good coding behavior" I mean how to maintain the code efficiently and based on changes in standard / release Have been optimized? For example: Delete Exclude Code, Use New Features
I'm just thinking about the right path about it? If some features are deprecated from one version to the next version, then do people go and change it in their codebase? Thanks Stack Overflow, I learn a lot here :)

I usually see the release notes .

If you need to track the versions and analyze their complete tracability on the vendor from the package, then I can tracability software to detect.

Spreadsheets do not cut it. :)
