Upgrade PHP from 8.1.32 to 8.3.x

[pinkbottle]

Hello,

I want to check if there will be any issue when I upgrade my php from 8.1.32 to 8.3.x?

I recently upgraded my Mantis to the below version:
MantisBT Version 2.28.0

PHP Version:
PHP 8.1.32 (cli) (built: Mar 11 2025 22:09:20) (NTS gcc x86_64)
Copyright (c) The PHP Group
Zend Engine v4.1.32, Copyright (c) Zend Technologies
with Zend OPcache v8.1.32, Copyright (c), by Zend Technologies

If I upgrade to php 8.3.x with the MantisBT version 2.28.0, will there be any issue? Any dependency need to take note of?

Thank you!

You should be absolutely fine – MantisBT 2.28.x runs without any trouble on PHP 8.4.20 on our end, so 8.3.x will certainly be no issue at all. (For reference: PHP 8.4 support was explicitly introduced with 2.28.0.)

That said, you may want to upgrade to MantisBT 2.28.1 regardless: a critical security vulnerability (CVE-2026-30849) affecting MySQL-based installations was identified in 2.28.0 and has been patched in 2.28.1. See the official announcement for details.
