Upgrade P4 Code Review
The section describes how to upgrade a P4 Code Review package or tarball installation to a newer release.
If you are not already running P4 Code Review, none of these instructions apply to you. Instead, see Install and upgrade P4 Code Review.
PHP version
To learn which versions of PHP P4 Code Review supports, see PHP. If the system does not have a supported version, a package installation or upgrade automatically ensures that you have the highest supported version. If the system already has a supported version, no change is made to the PHP version. You always have the option of using any supported version.
Redis and glibc version
The P4 Code Review 2024.3 release updated the Redis binary to version 7.2.4. Therefore, the kernel and glibc requirements changed from version 2.6 to 3.10. If you need to run Redis under kernel version 2.6, compile Redis from sources on the target host meeting the target kernel or use your own Redis installation.
