Important: #110501 - Slashes in page titles no longer end up in generated slugs 

Description 

The slug field of the pages table is generated from the page title. Until now, a slash contained in the title was kept as-is.

As a result, a page titled Terms / Conditions was given the slug /terms-/-conditions, and a page titled Support 24/7 was given the slug /support-24/7. The latter additionally introduces a path segment that does not exist as a page: the URL looks as if the page were a sub page 7 below a page /support-24.

The TCA of pages now configures a slug generator replacement that turns a slash into the fallback character -:

'slug' => [
    'config' => [
        'type' => 'slug',
        'generatorOptions' => [
            'fields' => ['title'],
            'fieldSeparator' => '/',
            'prefixParentPageSlug' => true,
            'replacements' => [
                '/' => '-',
            ],
        ],
        'fallbackCharacter' => '-',
        // ...
    ],
],

The generated slugs therefore change as follows:

Every slug generated from now on is affected, no matter whether it is built when a new page is created or when the slug is recreated from the title in the page properties. Slugs of existing pages are only changed once they are regenerated.

Manually entered slugs keep their slashes as before: a slash is a valid character in a page slug, it separates the path segments of a page.

Sites relying on the previous behavior can restore it by unsetting the new option in Configuration/TCA/Overrides/pages.php:

<?php

unset($GLOBALS['TCA']['pages']['columns']['slug']['config']['generatorOptions']['replacements']);
