This project is nearing a stable v1.0 release. Motivation ---------- [](#motivation) PSR-7 was designed for PHP, not Hack, and some descisions do not fit smoothly with Hack's type system. We would like agreement on a standardized interface before releasing v1.0 of several libraries that could and should use this. Additionally, with the planned end of PHP support in HHVM, it will stop being possible to use the canonical definitions or common implementations of PSR-7 in Hack code. Requirements ------------ [](#requirements) HHVM 4.41 and above.
