In order to address some lingering bugs, the PHP team pushed back the 7.0 release two weeks
PHP 7.0.0, a high-performance upgrade
to the popular server-side scripting language for Web development, was
due for a general release late last week. Instead, builders of the
language offered a seventh release candidate (RC).
Release candidates are generally considered the final precursor to a general release; the first release candidate for PHP 7.0.0 became available in August. But this seventh RC is supposed to finally lead to that general release, according to the PHP development team.
