5.7.3

Added

• Website identity verification for bots – The site can now prove its identity to automated systems (e.g. Cloudflare). It works much like a digital signature – the recipient can verify that a request really comes from your site.
• Catalogue of available services – A new machine-readable list of all public resources of the site (content for AI, sitemap and more). AI agents and tools can therefore discover automatically what your site offers.
• Better discoverability for AI agents – The home page now points directly to the machine-readable resources of the site in its HTTP response, so AI agents find them faster and more reliably.
• Content in Markdown for AI – When an AI agent requests a page in Markdown (instead of regular HTML), the site returns it in that format. Nothing changes for regular visitors in a browser.
• Rules for AI crawlers – The robots.txt file now contains a clear declaration: the site's content may be used for search and as a source for AI answers (so an AI agent can cite your brand guidelines correctly), but it may not be used to train AI models.

Fixed

• YouTube in the Video modules – The "Watch on YouTube" link on an embedded player no longer ends with a browser error (ERR_BLOCKED_BY_RESPONSE). The sandbox attribute, which prevented the YouTube video page from opening properly, has been removed from the iframe.
