• All versions support Windows. OS X and Linux support started with version 5.0.375. The Android 4 platform was first supported with version 16.0.4130.199 (Chrome for Android).^{[r 116][r 117][r 118]}
• Old development and beta builds are not shown after they become stable releases.
• As of Chrome version 26, Linux installations of the browser may be updated only on systems that support GCC v4.6 and GTK v2.24 or later. Thus systems such as Ubuntu Lucid 10.04 LTS, Debian 6's 2.20, and RHEL 6's 2.18 are now among those marked as deprecated.^{[r 119]}
• Version 6–32 had Google Chrome Frame counterparts, until its development was discontinued.^{[r 120]}
