PHP 8.5 INTERNALS UPGRADE NOTES
1. Internal API changes
2. Build system changes
3. Module changes
4. OpCode changes
5. SAPI changes
========================
1. Internal API changes
========================
- Zend
. Added zend_safe_assign_to_variable_noref() function to safely assign
a value to a non-reference zval.
. Added zval_ptr_safe_dtor() to safely destroy a zval when a destructor
could interfere.
. zend_get_callable_name() now returns the name of the underlying function
for fake closures.
========================
2. Build system changes
========================
- Windows build system changes
. SAPI() and ADD_SOURCES() now suport the optional `duplicate_sources`
parameter. If truthy, no rules to build the object files are generated.
This allows to build additional variants of SAPIs (e.g. a DLL and EXE)
without duplicate build rules. It is up to the SAPI maintainers to ensure
that appropriate build rules are created.
========================
3. Module changes
========================
- ext/gd
. The gdImageScale*() and gdImageRotate*() helpers are now internal in the
bundled libgd, like they have been in external libgd as of gd-2.1.1.
- ext/json
. php_json_encode_serializable_object() now assumes `EG(active)`,
if not a bailout is caused. Therefore a minor BC break exists if the
`PHP_JSON_PARTIAL_OUTPUT_ON_ERROR` option is in use.
However, this situation is highly unlikely.
- ext/libxml
. The refcount APIs now return an `unsigned int` instead of an `int`.
- ext/pdo
. Added `php_pdo_stmt_valid_db_obj_handle()` to check if the database object
is still valid. This is useful when a GC cycle is collected and the
database object can be destroyed prior to destroying the statement.

4. OpCode changes

5. SAPI changes
