Is PHP dependency ">=5.4.0" mandatory?

Can I use PHP ">=5.3.29" instead?

php.net: What has changed in PHP 5.4.x says

Most improvements in PHP 5.4.x have no impact on existing code. There are a few incompatibilities and new features that should be considered, and code should be tested before switching PHP versions in production environments

But I'm not able to review the github-api code and check if the few incompatibilities or new features are in use.

Any of Yes/No/Don't know answers is good enough for me as I can upgrade to PHP 5.4 I just want to know if it is necessary to undergo the hassle

No, you can not use PHP 5.3.29. PHP 5.4+ is required because short array notation and $this in closures is used.
