The PHP development team announces the immediate availability of PHP [5.6.17 and 5.5.31]. This is a security release. Several security bugs were fixed in this release. All PHP [5.6 and 5.5] users are encouraged to upgrade.
As always, you can down load the source of this latest release from the downloads page from the main site (or your mirror of choice) and the Windows binaries from windows.php.net. Full details of the changes in these two releases are included in the Changelog.
