Where can I get list of transaction codes for technical team (Basis/Security) that have been deprecated SAP S/4 HANA, as well as the new ones that have been introduced?

Is it only transaction codes, or any minor/major change in existing transaction codes? Why transaction codes only? The only way I know is just to keep you informed via "what's new" blog posts, documentation, etc.
