I found an interesting project protected by Apache-2.0 in github. Now I want to modify some functions and some new features to develop a new software based on the original project. Naturally I want to fork it and start my coding, but there is a confusing thing, should I fulfill the obligation of *Redistribute with  Modification, *especially the 2.nd term, changelog related.

You must honor licensing terms. However, the terms do not _require_ you to waste your (and others) time on polluting every modified source file with an ever-growing list of humans and bots that have touched it. The lawyers should not have relied on an overly specific term "file" in a general-purpose software license, but they gave us enough wiggle room to work around their shortcomings.

For example, IMO, the "prominent notice" may come in a form of "See the NOTICE file for details about this software modifications." text included in the beginning of every file (and the corresponding NOTICE file where you do record your name). This works especially well if you distribute your software via a version-control system that publishes every modification as metadata (e.g., GitHub).
