We have updated the following buildpacks for App Platform:

• PHP buildpack: We updated the buildpack to version 298 and added PHP versions 8.5.3-8.5.12, 8.4.18-8.4.27, 8.3.31-8.3.33, 8.3.35-8.3.36, and 8.2.31-8.2.35. PHP 8.5.12, 8.4.27, 8.3.36, 8.2.35, and 8.1.34 include fixes for two security vulnerabilities (CVE-2026-109618 and CVE-2026-109619). To use a patched runtime, force rebuild and deploy your app. If your composer.json pins an exact PHP version, update it to a range such as ^8.5.0 so a patched version can be selected. If you have an existing PHP app that uses v1, we recommend upgrading to v2.
• Node.js buildpack: We updated the buildpack to version 375 and added the following Node.js versions. Visit the Node.js buildpack to learn more about specifying a Node.js engine version. Node.js 25.x reached end-of-life and is deprecated.
• Node.js 22.22.3-22.23.4
• Node.js 24.16.0-24.22.1
• Node.js 26.0.0-26.12.1
• Python buildpack: We updated the buildpack to version 358 and updated supported Python aliases and package tooling. Apps that do not specify a Python version now use Python 3.14 instead of 3.13. If you are on Ubuntu-22 and have an existing Python app that is on v4, v3, v2, v1, or v0, we recommend upgrading to v5.
• Added Python 3.15.0-3.15.1
• Python 3.14 alias now resolves to 3.14.9
