We’ll sort this, but you can disable caching in your config.php to get it working in the meantime.

This is correct. I upgraded to PHP 8.3.4 and got the upgrade to complete.

Our bug bot is (was) broken! This is fixed for Beta 2.

Line numbers are different, but it looks like it's still an issue with 2.3 beta 3.

From the source, it just looks like 2.3 has a new format for host/port/weight. Easy enough to fix via change to config.php. For me, this:

$config['cache'] = [
    'enabled' => true,
    'sessions' => true,
    'namespace' => 'tx',
    'provider' => 'Memcached',
    'config' => [
        'servers' => [
            [$GLOBALS['digitalPoint']['Misc']['memcacheserver'][1], 11211, 1],
            [$GLOBALS['digitalPoint']['Misc']['memcacheserver'][2], 11211, 1],
        ]
    ]
];

becomes this:

$config['cache'] = [
    'enabled' => true,
    'sessions' => true,
    'namespace' => 'tx',
    'provider' => 'Memcached',
    'config' => [
        'servers' => [
            [
                'host' => $GLOBALS['digitalPoint']['Misc']['memcacheserver'][1],
                'port' => 11211,
                'weight' => 1
            ],
            [
                'host' => $GLOBALS['digitalPoint']['Misc']['memcacheserver'][2],
                'port' => 11211,
                'weight' => 1
            ]
        ]
    ]
];
