Switch the default test environment to PHP 8.4

Isn't it a bit too early for that? Still a lot of contrib modules still don't work well on PHP 8.3

solomon.yifru → made their first commit to this issue’s fork.

@danrod this is for core tests pipelines, we test on both PHP 8.4 and 8.3 every day, it has zero effect on contrib module test pipelines which are in the separate 'gitlab_templates' project.

I wonder would it make sense to switch to PHPUnit 11 for 8.4 too? And let 8.3 and below onto PHPUnit 10? https://stitcher.io/blog/php-version-stats-january-2025

In start of July first alpha of PHP 8.5 will arrive so no reason to wait

Added commit to switch MySQL to 8.4 (LTS) for the default pipeline

Ref https://dev.mysql.com/doc/refman/8.4/en/mysql-releases.html

Note: MySQL 8.0 is a Bugfix series that preceded the LTS release model.

lets do it!

8.0.34+ will transition to only bug fixes until 8.0 End-Of-Life (EOL) scheduled for April-2026

So nightly testing is good enough for support https://dev.mysql.com/blog-archive/introducing-mysql-innovation-and-long...
