I forgot to add UPGRADING for FILTER_THROW_ON_FAILURE and the 2 new classes that added, so it wasn't in #4886 originally - I just added that, can you include them here too?

TimWolla · 2025-10-20T06:47:54Z

php/php-src#20239 might also need to be incorporated

php/php-src#20278

Added in a288458.
However, it is not the UPGRADING file as-is; instead, content based on the RFC wording has been added.

Thank you for starting this! I left a lot of comments that I would like to have addressed. :)

appendices/migration85/deprecated.xml

+   <simpara>
+   <link linkend="language.operators.execution">The backtick operator</link>
+   as an alias for <function>shell_exec</function> has been deprecated.
+   </simpara>


Nit: indentation seems to be missing for the content of the simpara?

inentation fixed in 8b62bd4.

appendices/migration85/deprecated.xml

+  <simpara>
+   The <link linkend="object.wakeup">__wakeup()</link> magic method of
+   <interfacename>DateTimeInterface</interfacename>,
+   <classname>DateTime</classname>, <classname>DateTimeImmutable</classname>,
+   <classname>DateTimeZone</classname>, <classname>DateInterval</classname>,
+   and <classname>DatePeriod</classname> has been deprecated in favour of
+   the <link linkend="object.unserialize">__unserialize()</link> magic method.
+   <!-- RFC: https://wiki.php.net/rfc/deprecations_php_8_5#deprecate_the_sleep_and_wakeup_magic_methods -->
+  </simpara>


I don't remember if this wasn't reverted with the soft deprecation RFC, so this would need to be removed.

ok. deleted in eaa8c68.

Girgias · 2025-10-29T14:22:30Z

appendices/migration85/deprecated.xml

+   The <constant>MHASH_<replaceable>*</replaceable></constant> constants
+   have been deprecated.  These have been overlooked when the mhash*() function
+   family has been deprecated per
+   <!-- RFC: https://wiki.php.net/rfc/deprecations_php_8_1#mhash_function_family -->


This text doesn't make much sense as the RFC which is being linked to is in a comment

ok. deleted mhash*() related description in dc23d16.

Girgias · 2025-10-29T14:47:27Z

appendices/migration85/new-features.xml

+    The <link linkend="language.oop5.cloning">clone language construct</link>
+    is now a function and supports reassigning (readonly) properties during
+    cloning via the new <property>$withProperties</property> parameter.
+    <!-- RFC: https://wiki.php.net/rfc/clone_with_v2 -->


@TimWolla it cannot be disabled via disable_functions right?
