EXAMPLE COMMIT MESSAGES: POOR
==============================
These commit messages name a category of change but not what actually changed.
They are slightly better than nothing, but still force anyone reading the history
to open the commit and read the diff to understand what happened.

--------------------------------------------------

What changed:
  Fixed the search box so that queries containing spaces no longer return zero results.
  The bug was caused by the search string not being URL-encoded before the API call.

Commit message used:
  "fixed bug"

--------------------------------------------------

What changed:
  Added validation to the file upload function to reject any file over 10MB
  and return a clear error message to the user explaining the size limit.

Commit message used:
  "updated file"

--------------------------------------------------

What changed:
  Changed the call-to-action button on the homepage from blue (#2c365e) to green (#355E3B)
  based on feedback from the client during the design review meeting.

Commit message used:

--------------------------------------------------

What changed:
  Added a button on the user dashboard that lets users export all of their data
  as a downloadable CSV file, including account details and activity history.

Commit message used:
  "new feature"

--------------------------------------------------

What changed:
  Rewrote the list-sorting function because the previous version used a bubble sort,
  which was causing the page to time out on lists longer than 500 items.
  Replaced with a quicksort implementation, reducing worst-case time from O(n²) to O(n log n).

Commit message used:
  "better"
