PHP 지원기간 안내 (PHP Supported Versions) – 201809현재

2018-09-03 KENNETH 0

URL : http://php.net/supported-versions.php   Supported Versions Each release branch of PHP is fully supported for two years from its initial stable release. During this period, bugs and security issues that have been reported are fixed and are released in regular point releases. After this two year period of active support, each branch is then supported for an additional year for critical security issues only. Releases during this period are made on an as-needed basis: there may be multiple point releases, or none, depending on the number of reports. Once the three years of support are completed, the branch reaches its end of life and is no longer supported. A table of end of life branches is available. Currently Supported Versions Branch Initial Release Active Support Until Security Support Until 5.6 * 28 Aug 2014 4 years ago 19 Jan 2017 1 year, 7 [ more… ]
