 ## PHP Settings Still Apply
 Octane does not change how PHP loads its configuration. FrankenPHP reads the same `php.ini` files from `/usr/local/etc/php/conf.d/` in every mode, so all of the `PHP_*` environment variables (like `PHP_MEMORY_LIMIT` and `PHP_OPCACHE_ENABLE`) work exactly as they do in classic mode. Any custom `.ini` files you mount into that directory apply as well.

 #### FrankenPHP: `REMOTE_ADDR` is now the client IP resolved from trusted proxies
 Version 4 set `$_SERVER['REMOTE_ADDR']` to the TCP peer on FrankenPHP, even when Caddy had already worked out the real client IP for the access log. It now matches what Caddy resolved, the same as NGINX and Apache, and Caddy runs in strict mode so a client behind a trusted proxy cannot forge it. You are affected if anything in your app compares `REMOTE_ADDR` to a proxy's address. [Read the trusted proxies guide →](/docs/guide/configuring-trusted-proxies)
 
+#### FrankenPHP: Mercure 1.0 rejects `publisher_jwt` and `subscriber_jwt`
+Version 5 ships FrankenPHP 1.13, which includes Mercure 1.0. If you enable the Mercure hub with `publisher_jwt` or `subscriber_jwt`, including through the `mercure` array in `config/octane.php`, FrankenPHP now fails to start. Move the keys into an `issuer` block as shown in [FrankenPHP's Laravel guide](https://frankenphp.dev/docs/laravel/#mercure-support){target="_blank"}, or add `protocol_version_compatibility 8` to keep your current settings while you migrate. The [Mercure 1.0 upgrade guide](https://github.com/dunglas/mercure/blob/v1.0.3/docs/UPGRADE.md){target="_blank"} covers the client changes.
+
+#### FrankenPHP: Caddy limits request headers
+FrankenPHP 1.13 includes [Caddy 2.11.7](https://github.com/caddyserver/caddy/releases/tag/v2.11.7){target="_blank"}. Requests with more than 16 KiB of headers now get a `431 Request Header Fields Too Large` response, where Version 4 allowed 1 MB. Large cookies are the usual cause. Headers with a `.` in their name are now dropped, like headers with a `_`, because PHP reads both as `-` and a client could use them to spoof headers like `X-Forwarded-For`.
+
+#### FrankenPHP: `num_threads` no longer includes worker threads
+If you set `num_threads` in `FRANKENPHP_CONFIG` while running workers, including Laravel Octane, FrankenPHP now starts that many threads on top of the worker threads, and fails to start if `max_threads` is lower than the total. Lower `num_threads` to the number of threads you want for regular requests.
+
 ### Fixes
 - `PHP_OPCACHE_FORCE_RESTART_TIMEOUT` existed in Version 4 but never reached `php.ini`. It now works. The default of `180` matches PHP's own default, so nothing changes unless you had set it to something else.
