Changes between Version 2 and Version 3 of Ticket #50639, comment 11

v2	v3
1		Looking at the media test failures, they appear to be caused by [https://github.com/WordPress/wpdev-docker-images/blob/84a4acfc15fd0bff04e3342e5c24a2c0ce5211cf/update.php#L181 missing 'gd' extension] in the [https://github.com/WordPress/wpdev-docker-images WP Docker image]. That includes tests explicitly checking for `imagejpeg()` and failing with "jpeg support unavailable", as well as tests implicitly relying on GD availability without specifically checking for it, causing more obscure failures.

That includes tests explicitly checking for `imagejpeg()` and failing with "jpeg support unavailable", as well as tests implicitly relying on GD availability without specifically checking for it, causing more obscure failures. So consistently requiring GD functions where needed seems like the next step here.

3	3	The Docker image should probably be updated to provide the same list of extensions for PHP 8 that we currently have for PHP 7.4 and older: `gd`, `opcache`, `mysqli`, `zip`, `exif`, `intl`, `mbstring`, `xml`, `xsl`. If anyone is able to help with that and open a PR, please do :)
