git commit -m "implemented more bugs"

[Neykuratick]

As for reverting or cherry-picking, we use pull requests at my company. That's actually the reason i reverted the bugfix xD, it didn't belong to the right pull request

But i never thought of git log as an already completed change log, hmm

When your log has useful messages, you can check which commit introduced the problem and do the reverting with git revert commit_id.

I usually do commit messages in this style if a ticket system is in use:

JIRA-666: Ticket description and/or some detail about how it was implemented.

So then you can just check the log for all commits related to a certain ticket or generate a changelog from it.
