Chance of loose something becouse of update

Question

If i change (use in qa-theme.php) for example function main(), i can loose something that would be new in next Q2A version, at  function main() ?

Answer 1

So long as you do this in your own theme file, and not in qa-theme-base.php, you should be safe, unless some new type of content is added to Q2A. If possible I recommend making some changes as necessary then calling back to the base theme using qa_html_theme_base::main() to minimize this risk.
