This is a first public release.

PHP 7 only (>= 7.0), including PHP 7.1.

This release works best with V8 Google JavaScript engine version 5.2 installed. At this time extension tested using 5.2.371.

For Ubuntu there are pinepain/libv8-5.2 PPA. To install fresh libv8 do:

$ sudo add-apt-repository ppa:pinepain/libv8-5.2 -y
$ sudo apt-get update -q
$ sudo apt-get install -y libv8-5.2-dev

For OS X there are v8.rb homebrew formula. To install fresh libv8 do:

$ brew install https://raw.githubusercontent.com/pinepain/php-v8/v0.1.0/scripts/homebrew/v8.rb

No windows support at this time, though, there should be nothing preventing to add it except of getting how to properly package V8 itself for windows.
