Previous version tar.gz wasn't available anymore. Updated to the new version. This should also fix the sierra bottle issue #6408 for this formula.

I don't think we need to override the version here.

@ilovezfs Without the override, the default version is 0.

@ilovezfs FYI audit will 💥 if a version is specified unnecessarily.

Thanks again for your contribution to Homebrew! Without people like you submitting PRs we couldn't run this project. You rock!

For future reference the preferred commit message format is ipbt 20160908. Please complete the issue template in future PRs where this format is detailed in the linked Contributing guidelines. Thanks!

I guess the prior version scanned correctly because the git hash coincidentally had no a-f in the hex. Yikes, and then some more yikes.

@MikeMcQuaid Yes, I know. The prior version scans as 20141026.2197432 so a version "20141026" would not be redundant.
