Upper case Jira tickets in commit message are ignored?

[james-hu]

It seems that commits with messages like fix(ABC-123): my message are ignored while those with messages like fix(abc-123): my message are not.

Here's the code, I guess instead of "a-z", it should be "a-zA-Z":

const prefixMatcher = prefixes && new RegExp(`^(${prefixes.join('|')})(\\([a-z0-9\\-_,]+\\))?:\\s.+$`)
