This weekend I finally had time to spin up a VM with pecl_http version 1 installed and write a full suite of tests against the original function. As far as I can tell we are now up to 100% parity! There were a few minor changes that were BC breaks from the ~0.0.2 release, but since there have only been 8 downloads I'm not too worried about it 😄
This release is fully compatible with PHP 5.3+ and HHVM.
