+> **Upgrade note:** `Phalcon\Html\Link\LinkProvider::getLinks()` and `Phalcon\Html\Link\EvolvableLinkProvider::getLinks()` now return arrays keyed by `spl_object_id()` (integers) instead of `spl_object_hash()` (strings). Code that builds or looks up these keys with `spl_object_hash()` must use `spl_object_id()`. `getLinksByRel()` is not affected. [#17687](https://github.com/phalcon/cphalcon/issues/17687)
+
+> **Upgrade note:** `Phalcon\Session\Adapter\AbstractAdapter` and `Phalcon\Session\Adapter\Noop` now implement `SessionIdInterface` with `create_sid(): string`. Subclasses that override `create_sid()` must declare the `string` return type. New session IDs now come from the adapter as 32 hex characters, so `session.sid_length` and `session.sid_bits_per_character` no longer apply to these adapters. Custom handlers that implement `SessionHandlerInterface` directly must add `create_sid()` and `validateId()` to avoid the PHP 8.6 deprecation.
