v1.1.0.8 could not be installed: on PHP 8.5 Composer could not resolve it (PhpSpreadsheet), and on 8.4 and older a Composer script stopped on framework.trusted_proxies. v1.1.0.9 fixes that and the errors a fresh install showed after it:

• Updated: TRUSTED_PROXIES is read as a string (Symfony 5.4); minimums for the forks that replace their upstream packages, so no package is installed twice (606 ambiguous-class warnings, auto-scripts that never ran, admin translations 404).
• Updated: Node.js 20 (today's front-end dependencies no longer install on 18); the Ibexa 4 ez.config.setup.js hook is removed (yarn ez failed).
• Updated: the installer reindexes SQLite in one process ("database is locked").
• Updated: the demo data names the component block definitions this line has, the component templates guard missing fields and links, and each site group sets its own site info (Bold Agency showed Fit & Healthy menus).
• Added: a compiler pass for the Site API 4 content view parameter (dev /bold_* returned 500) and a Layouts editor preview override (the editor API returned 500 for layouts with component blocks).
• Requires: se7enxweb/information-collection-bundle v2.0.4 (PhpSpreadsheet up to 5.x, so PHP 8.5 resolves) and se7enxweb/site-bundle 2.1.5.3 (ngsite_group_fields, the features grid plugin).
• PHP 8.0 stays supported: every Twig 3 release that still supports PHP 8.0 has advisories, so Composer 2.10 needs COMPOSER_NO_SECURITY_BLOCKING=1 there; PHP 8.1 or later is recommended (doc/INSTALL.md).

Known: 17 advisories (Guzzle 6, PSR-7 1.x, Flysystem 1, graphql-php 0.13) with no fix on Platform 3.3.

Verified with fresh installs of these commits on PHP 8.5 and 8.1: every documented step exits 0, pages, sign-in and the Layouts admin pass, image and file storage 28/28, the editor API loads all 21 layouts, no ERROR in the logs.
