What is the difference between bug fix, bugfix, bug fixes, bug fixing and fix bug? [closed]

I need to report about the tasks I've done related to fixing bugs and errors in software development. So how to express the task that I fixed a software bug?

Some use bug fixes but many also prefer to use fix bugs. In particular, these words are used in commit messages. Which are commonly used and correct in the world of software development?

Here's the difference:

Bug fix: Here fix means something that solves a problem, i. e. corrects a bug. For example, a patch can result in a bug fix.

Bug fixes: The plural form of the above.

Bug fixing: The activity of correcting software defects. Example: We've done a lot of bug fixing recently.

(To) fix a bug: Fix is a verb here, denoting the action of correcting a software defect.

bugfix: (computing) A patch or change that fixes unwanted behaviour due to a bug.

If it's a report you're writing, you can simply start with "The following bugs have been successfully fixed:", and then add a bulleted list.
