PHP 7 developers worked really hard to reduce memory consumption and to increase performance. And they certainly succeeded in it \u2014 we tested. X-Cart sites, compatible with the latest PHP 7, are as \u2018fast and furious\u2019 as never.<\/p>\n\n\n\n<p>Have a look at our TTFB (Time To First Byte) test results:<\/p>\n\n\n\n<div class=\"gb-table gb-table--3-cols\" role=\"table\">\n    <div class=\"gb-table__thead\" role=\"rowgroup\">\n        <div class=\"gb-table__tr\" role=\"row\">\n            <div class=\"gb-table__td gb-table__th\">&nbsp;<\/div>\n            <div class=\"gb-table__td gb-table__th\" role=\"cell\">PHP5<\/div>\n            <div class=\"gb-table__td gb-table__th\" role=\"cell\" style=\"background:#CCFFCC\">PHP 7<\/div>\n         <\/div>\n    <\/div>\n    <div class=\"gb-table__tbody\" role=\"rowgroup\">\n        <div class=\"gb-table__tr\" role=\"row\">\n            <div class=\"gb-table__td gb-table__th\" role=\"cell\"><span class=\"nobr\">X-Cart 4<\/span><\/div>\n            <div class=\"gb-table__td\" role=\"cell\">up to 0.5&nbsp;seconds<\/div>\n            <div class=\"gb-table__td\" role=\"cell\" style=\"background:#CCFFCC\"><span class=\"nobr\">0.2-0.4<\/span> seconds<\/div>\n        <\/div>\n        <div class=\"gb-table__tr\" role=\"row\">\n            <div class=\"gb-table__td gb-table__th\" role=\"cell\"><span class=\"nobr\">X-Cart 5<\/span><\/div>\n            <div class=\"gb-table__td\" role=\"cell\">up to 1&nbsp;second<\/div>\n            <div class=\"gb-table__td\" role=\"cell\" style=\"background:#CCFFCC\"><span class=\"nobr\">0.2-0.4<\/span> seconds<\/div>\n        <\/div>\n    <\/div>\n<\/div>\n\n\n\n<p>Good news is that X-Cart 5.3 and X-Cart 4.7.6 are already fully compatible with PHP 7. And though other versions do not support it out-of-the-box, it can be easily fixed \u2014 just apply our newly-baked PHP 7 compatibility patches.<\/p>\n\n\n\n<p>PHP 7 compatibility fixes are now available for the following X-Cart 4 versions:<\/p>\n\n\n\n<p>4.4.5 (php70x-2016-10-25_4.4.5.tgz)4.5.5 (php70x-2016-10-25_4.5.5.tgz)4.6.0 \u2013 4.6.6 (php70x-2016-10-25_4.6.x.tgz), where x is a version number4.7.0 \u2013 4.7.5 (php70x-2016-10-25_4.7.x.tgz), where x is a version number<\/p>\n\n\n\n<p>Patches for 4.4.0 \u2013 4.4.4 and 4.5.0 \u2013 4.5.4 versions should be adapted from 4.4.5 and 4.5.5 versions accordingly.<\/p>\n\n\n<h3>\n            Where can you find them?    <\/h3>\n\n\n\n<p>Log in to your personal&nbsp;<a href=\"https:\/\/secure.x-cart.com\/\" target=\"_blank\">HelpDesk<\/a>&nbsp;account \u2192 File area \u2192 X-Cart 4 \u2192 Your X-Cart version \u2192 Updates and patches.<\/p>\n\n\n<h3>\n            What\u2019s next?    <\/h3>\n\n\n\n<p>Ask your hosting provider if it\u2019s possible to upgrade your server PHP version to PHP 7. It will make your store as quick as a flash. Then you\u2019ll have two options available:<\/p>\n\n\n\n<ul class=\"checklist darkblue gb-list__check gb-list__check--blue wp-block-list\">\n<li>You can apply fixes to your current X-Cart 4 version. They will make your existing X-Cart 4 store compatible with PHP 7 without upgrading it to X-Cart 5. Just make sure everything works smoothly on the \u2018dev\u2019 copy of your web store before deploying patches on your live stores.<\/li>\n\n\n\n<li>Upgrade your store to X-Cart 5.3 or X-Cart 4.7.6. These versions already support PHP 7 and are extraordinarily fast. And don\u2019t worry, upgrading your store is not that scary. Here\u2019s the real-world example to inspire you:<\/li>\n<\/ul>\n\n\n\n<p><strong>Furttunato Cianfrocco from Oneida Suzuki upgraded his X-Cart 4.0.19 to X-Cart 4.7.6:<\/strong><\/p>\n\n\n\n<p>I had a store at 4.0.19 that I have wanted to upgrade to a modern version of x-cart. The store was up-to-date with security patches but that was it. There were some minor customizations but nothing too crazy; most customizations were actually no longer necessary in the latest x-cart. It was going strong for over 10 years (since ~2004) but it was getting long in the tooth with limitations such as mobile viewing (impacted google shopping), payment methods, look and feel, social media integration, etc\u2026<\/p>\n\n\n\n<p>I\u2019ve been considering an upgrade for a few years now and the numerous major revisions were always a concern for me; each major revision upgrade is just a lot of room for error. Supporting the store is my free-time job and I just didn\u2019t have the time to dedicate to the upgrade.<\/p>\n\n\n\n<p>We contracted x-cart to perform the upgrade and it couldn\u2019t have been better. They completed the upgrade very quickly, professionally, and had an upgraded store in their sandbox ready to test within a week!!! We had a few minor upgrade issues, nothing that I wouldn\u2019t expect in such an upgrade) that we worked through on the sandboxed upgrade. We purposely took our time (~2-3 weeks) to make sure the upgrade was production ready and x-cart was very patient. They also installed a few new modules in addition to the main store upgrade. x-cart also handled the actual migration on our web server.<\/p>\n\n\n\n<p>The upgraded store has been running for about 2 months now without any issues. I know I could have never completed the upgrade in the same amount of time or as seamless. For an upgrade of over 10 years of software, the upgrade cost was very reasonable and performed timely. It is also a testament to x-cart\u2019s robustness that the 4.0 store held out for so long.<\/p>\n\n\n\n<p>Thank you x-cart (Olga Tereshina, Alexey Galkin, and others)!<\/p>\n\n\n\n<p>Anyway, we are always ready to help, just contact us.<\/p>\n\n\n    <div class=\"gb-btns__wrapper\">\n                                    <a  href=\"https:\/\/www.x-cart.com\/contact\" class=\"btn btn--lg\" target=\"_blank\">Make my store PHP7-compatible<\/a>                        <\/div>\n\n\n<h2>\n            Dirty COW Vulnerability: the fix is here!    <\/h2>\n\n\n    <div class=\"gb-img__figure-container\">\n        <figure class=\"gb-img__figure\">\n                            <picture><source  srcset=\"https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1-p500.jpg 1x, https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1-p760.jpg 2x, https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1.jpg 3x\" type=\"image\/jpg\" media=\"(max-width: 420px)\" \/><source  srcset=\"https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1-p950.webp 1x, https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1.webp 2x\" type=\"image\/webp\" media=\"(min-width: 421px)\" \/><source  srcset=\"https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1.png 1x\" type=\"image\/png\" media=\"(min-width: 421px)\" \/><img decoding=\"async\"  width=\"1040\" height=\"404\" src=\"https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1.png\" srcset=\"https:\/\/www.x-cart.com\/img\/22785\/dirtycowxcart3-1.png 1x\" alt=\"Dirty Cow\" loading=\"lazy\" \/><\/picture>                                <\/figure>\n    <\/div>\n    \n\n\n<p>On October 18, 2016 a serious Linux kernel vulnerability, allowing users to easily get persistent root access, was disclosed.
