Description
For understanding what is going on here it would be very helpful to have the commit messages in English.
They actually could contain both Japanese and English messages if this would be helpful for the Japanese users.
The old messages can be changed, too - see https://help.github.com/articles/changing-a-commit-message/
In general there is are two things missing:
a) "user viewable changes" - NEWS file - you actually did a quite good job to provide the messages in https://github.com/opensourcecobol/opensource-cobol/releases - they only are missing from the NEWS file - please copy them over and commit the file.
Afterwards it is fine to change the NEWS file when preparing a new release.
b) Changelog entries - not every minor change needs them but it is good to have entries for most changes. I assume the commit messages can be used as a first "source" for them, you may see missing stuff when copying them (translated to English) into the Changelogs.
Afterwards Changelog entries are ideally always done during a change and committed along the actual change.
Thank you for responding.
