Edge

Added

• edge/cache/refresh-expired purges pages whose content changed status on its own: a scheduled post going live, an entry expiring. Craft fires no event at those moments, so run this on a schedule (a per-minute cron is fine — it is two indexed lookups).

Fixed

• Project config changes (fields, entry types, sections, site settings) now invalidate.

Changed

• edge_caches gains an expiryDate column; the schema version is now 1.1.0.

Fixed

• Content inside a {% cache %} block is now tracked, so pages using the tag invalidate.
• Invalidation triggered inside a queue job is no longer discarded.
• Pricing change invalidation for Commerce catalog pricing rules.
• End-of-request flush handlers no longer accumulate in long-lived queue workers.

Changed

• Pages whose {% cache %} blocks run unscoped element queries now invalidate more widely, because those dependencies are recorded for the first time. Scope the queries to narrow it.
• A change resolving to at least half the cached tier is flushed wholesale rather than as thousands of individual purge and warm jobs. Same purge scope, one job.
• configWarnings() documented its return type as the verify result; corrected to string[].

Added

• docs/reverse-proxy.md documents the Apache h2c trap. With mod_http2 enabled (the Debian/Ubuntu default ships Protocols h2 h2c http/1.1), Apache answers plain HTTP with Upgrade: h2,h2c + Connection: Upgrade, which breaks nginx keepalive reuse: reused connections return 200 with an empty body. Small JSON responses fail most of the time while full pages mostly succeed, so edge/hydrate, edge/csrf and Craft's own session-info silently return nothing and every form on a cached page stops working. Pin the backend vhost to Protocols http/1.1.

Changed

• The bundled example app now reflects current behaviour: templates use {{ edgeCsrfInput() }}, config/edge.php sets cacheLoggedInRenders, config/general.php carries the correct trustedHosts/ipHeaders pairing, and the nginx config gained the cache-key-aware bypass rule, a /actions/ location and browser revalidation on cache hits.

Added

• {{ edgeCsrfInput() }} Twig function. Emits a token-free placeholder on a page that is being cached (the hydration runtime fills it per visitor) and the real token inline on a page that isn't — an excluded URI, a bypass, a signed-in render, an island fragment. A shared form partial no longer needs a flag threaded through it to say which kind of page it landed in, and the uncached case costs no round trip and needs no JavaScript.
• The Edge Cache utility and edge/nginx/verify now warn when queryStringCaching is respect on the nginx-static driver. That combination silently writes one file per query string that the tier can never look up, because it serves <host>/<uri>/index.html with no place for a query segment.

Fixed

• The shipped nginx configs now bypass the cache for any request carrying a query param that isn't in excludedQueryStringParams. Without it, /shop?brand=x was answered from the unfiltered /shop entry, since ignore mode leaves the query string out of the key. tests/guards.php asserts the map and the origin guard agree case by case.
• location @edge now sends Cache-Control: public, max-age=0, must-revalidate on a hit. nginx serves the stored file verbatim, so the origin's headers never reached the visitor and browsers fell back to heuristic freshness — holding pages for an unpredictable window that no purge could reach.

Changed

• Plugin::proxyWarnings() is now Plugin::configWarnings() and covers driver/query-mode mismatches as well as trusted-proxy problems.

Fixed

• A response rendered for a Host other than the site's configured base-URL host is no longer stored. The cache file is keyed by the site's own host while Craft renders absolute URLs from the request Host, so a request arriving on another host (a bare IP, a forged Host) could write its URLs into the canonical entry and have them served to every visitor. Such requests still render normally.
• Cacheable responses now send public, s-maxage=<cacheControlTtl>, max-age=0, must-revalidate instead of public, max-age=<cacheControlTtl>. max-age is a browser directive, and a purge can never reach a browser: the previous header let a visitor hold stale HTML for the full TTL (a year, by default) with no way to recall it.
• In queryStringCaching: 'ignore' mode, a request carrying a query param that isn't in excludedQueryStringParams is no longer stored. The query string is dropped from the cache key in that mode, so /shop?brand=x was being written over the entry for plain /shop. Marketing params are excluded by design and still cache.
• CSRF hydration no longer races island hydration. The token is fetched once and applied again to each island fragment after it swaps in, before edge:island fires, so forms inside islands are filled.
• CSRF hydration now fills Craft's async <craft-csrf-input> placeholder, which Formie also emits and which asyncCsrfInputs produces. Previously only plain inputs were filled.

Added

• cacheLoggedInRenders setting (default false). The edge tier already serves the shared copy to signed-in visitors, but their renders were never stored, so a page browsed only by signed-in staff never warmed. Enable it when the shell is identity-independent.
• A response containing a rendered CSRF token (an input named after csrfTokenName with a non-empty value) is refused and logged instead of being stored with a token baked in.
• A response containing the signed-in user's email, username or full name is refused and logged when cacheLoggedInRenders is on. The matched field name is logged, never its value. This catches the obvious leak only; it cannot see group-scoped pricing or permission-scoped elements.
• X-Edge-Skip-Reason header on non-cacheable responses in devMode, naming the rule that matched.
• The Edge Cache utility and edge/nginx/verify warn when trustedHosts contains any while ipHeaders is set, which lets any client spoof its IP through X-Forwarded-For.
• window.EdgeCsrf.ensure(root) / .apply(root) for filling CSRF fields in markup a site injects itself.
• docs/reverse-proxy.md, covering trustedHosts / ipHeaders for both proxy topologies.
• The shipped nginx configs gained a location ^~ /actions/ block, a default_server catch-all recipe, and a reverse-proxy variant for origins that aren't FastCGI. Without a .php handler, try_files $uri resolves /index.php to the file on disk and nginx serves the PHP source.
• tests/guards.php, a framework-free self-check for the pure guards (php tests/guards.php).

Changed

• CacheDriverInterface::prepareResponse() takes an optional fourth argument, ?string $skipReason. Drivers extending BaseDriver need no change; a driver implementing the interface directly must update its signature.

• Initial release.
