Stop updating ChangeLog?

Hi all,
The discussion in this thread
https://sourceware.org/ml/gdb-patches/2018-02/msg00012.html
leads to a discussion that whether we still need ChangeLog.  I start
a new thread to get more attention on this topic.

In current development, we need to write one ore more changelog
entries for each commit, put them into both git commit log and
ChangeLog files.  How much we can change to existing mode
depends the answers to these following questions,

 #1 Are ChangeLog files useful in GDB releases to various people
 who build GDB releases?
 #2 Are ChangeLog files useful in GDB repo to various GDB
 developers?

a) If answers are Yes/Yes, we keep unchanged,
b) If answers are No/No, we don't need to write changelog entries in
git commit log, nor updating ChangeLog file,
c) If answer are Yes/No, developers still have to write changelog
entries in git commit log, and we can generate ChangeLog on
release from git log.
d) If answers are No/Yes, get use to git to get the information from
git log instead of ChangeLog,

My answers are No/No, so I suggest that we do b).  I can live up with
c), but that needs change in the release process.  What do you think?

P.S. I found that this topic has been discussed several times in
various projects (binutils, glibc, etc) without any conclusions.  I do
hope we can make some progress this time :)
