 ========================
 
-- Core
-  . PG(arg_separator).input and PG(arg_separator).output are now `zend_string*`
-    instead of `char*`.
-  . DL_LOAD now doesn't use RTLD_DEEPBIND deepbind anymore on platforms
-    where dlmopen with LM_ID_NEWLM is available:
-    this means shared library symbol isolation (if needed) must be enabled on
-    the user side when requiring libphp.so, by using dlmopen with LM_ID_NEWLM
-    instead of dlopen.
-    RTLD_DEEPBIND is still enabled when the Apache SAPI is in use.
-  . The ptr field of the php_stream_notifier struct is now a void* instead
-    of a zval. If the zval was used to store IS_PTR values only, the
-    extra layer of indirection can be removed. In other cases a zval can
-    be heap-allocated and stored in the pointer as a minimal change to keep
-    compatibility.
+* zend_register_module_ex() now takes an additional int module_type argument.
+  This function will also assign the module number and type, there is no need
+  to do this at the call site anymore. Writing the handle should happen after
+  successful registration.
 
-- Hash
-  . Hash functions now use proper hash_spec_result enum for return values
-    instead of using SUCCESS and FAILURE.
+* ZPP now accepts a F or Z_PARAM_FUNC_NO_TRAMPOLINE_FREE type check.
+  This is identical to the 'f' or Z_PARAM_FUNC type check, except the FCC is
+  always initialized because it doesn't free trampolines.
+  Trampolines MUST be freed using zend_release_fcall_info_cache() or consumed.
+  Z_PARAM_FUNC_EX2 was added as well with the same arguments as Z_PARAM_FUNC_EX
+  plus an additional argument free_trampoline.
 
-- 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.
-  . Added smart_string_append_printf() matching smart_str_append_printf() for
-    char* instead of zend_string*-based smart strings.
-  . Added php_build_provider() to retrieve the value of PHP_BUILD_PROVIDER at
-    runtime.
-  . Removed the cache_slot argument of zend_check_user_type_slow() because
-    now it only relies on the CE cache.
-  . Added ZEND_NONSTRING attribute macro for character arrays that do not
-    represent strings. This allows to silence the GCC 15.x
-    `-Wunterminated-string-initialization` warning.
-  . Added the zend_update_exception_properties() function for instantiating
-    Exception child classes. It updates the $message, $code, and $previous
-    properties.
-  . zend_exception_get_default() was removed, use zend_ce_exception directly.
-  . zend_get_error_exception() was removed, use zend_ce_error_exception
-    directly.
-  . ZEND_IS_XDIGIT() macro was removed because it was unused and its name
-    did not match its actual behavior.
-  . The following zend_string-related legacy aliases were removed:
-    * IS_INTERNED() - use ZSTR_IS_INTERNED()
-    * STR_EMPTY_ALLOC() - use ZSTR_EMPTY_ALLOC()
-    * _STR_HEADER_SIZE - use _ZSTR_HEADER_SIZE
-    * STR_ALLOCA_ALLOC() - use ZSTR_ALLOCA_ALLOC()
-    * STR_ALLOCA_INIT() - use ZSTR_ALLOCA_INIT()
-    * STR_ALLOCA_FREE() - use ZSTR_ALLOCA_FREE()
-  . zend_register_constant() now returns a pointer to the added constant
-    on success and NULL on failure instead of SUCCESS/FAILURE.
-    The specialized registration methods that previously had void returns
-    also return pointers to the added constants:
-    * zend_register_bool_constant()
-    * zend_register_null_constant()
-    * zend_register_long_constant()
-    * zend_register_double_constant()
-    * zend_register_string_constant()
-    * zend_register_stringl_constant()
-  . EG(fake_scope) now is a _const_ zend_class_entry*.
-  . zend_begin_record_errors() or EG(record_errors)=true cause errors to be
-    delayed. Before, errors would be recorded but not delayed.
-  . zend_mm_refresh_key_child() must be called on any zend_mm_heap inherited
-    from the parent process after a fork().
-  . HASH_KEY_IS_* constants have been moved in the zend_hash_key_type enum.
+* The zend_object_iterator_funcs valid member has changed its signature from
+  int(*)(zend_object_iterator *) to zend_result(*)(zend_object_iterator *) to
+  be more in line with what callbacks are returning.
 
-- standard
-  . ext/standard/php_smart_string.h and ext/standard/php_smart_string_public.h
-    were removed. Use the corresponding headers in Zend/ instead.
+* The backwards compatibility headers ext/standard/{php_lcg.h,php_mt_rand.h,
+  php_rand.h,php_random.h} have been removed. Include ext/random/php_random.h
+  directly.
+
+* The zend_*printf family of functions now supports the "%S" modifier to print
+  out zend_string*. This won't cut off the string if it embeds a NUL byte.
+
+* The inet_aton() and win32/inet.h have been removed. Use platform-agnostic
+  inet_pton() from arpa/inet.h or ws2tcpip.h on Windows.
+
+* zend_mm_set_custom_debug_handlers() has been removed from ZendMM, use
+  zend_mm_set_custom_handlers() instead which now supports DEBUG builds
+
+* zend_mm_set_custom_handlers() has changed its signature from
+  void()(zend_mm_heap *heap,
+         void* (*_malloc)(size_t),
+         void  (*_free)(void*),
+         void* (*_realloc)(void*, size_t))
+  to
+  void()(zend_mm_heap *heap,
+         void* (*_malloc)(size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC),
+         void  (*_free)(void* ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC),
+         void* (*_realloc)(void*, size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC))
+
+* zend_mm_get_custom_handlers() has changed its signature from
+  void()(zend_mm_heap *heap,
+         void* (**_malloc)(size_t),
+         void  (**_free)(void*),
+         void* (**_realloc)(void*, size_t))
+  to
+  void()(zend_mm_heap *heap,
+         void* (**_malloc)(size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC),
+         void  (**_free)(void* ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC),
+         void* (**_realloc)(void*, size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC))
+
+* Added gc and shutdown custom handlers, settable via
+  zend_mm_set_custom_handlers_ex()
+
+* __zend_malloc() has changed their signature from
+  void(*)(size_t) to
+  void(*)(size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC)
+
+* __zend_calloc() has changed their signature from
+  void(*)(size_t, size_t) to
+  void(*)(size_t, size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC)
+
+* __zend_realloc() has changed their signature from
+  void(*)(void *, size_t) to
+  void(*)(void *, size_t ZEND_FILE_LINE_DC ZEND_FILE_LINE_ORIG_DC)
+
+* zend_observer_remove_begin_handler() and zend_observer_remove_end_handler()
+  got each a new parameter returning an observer which must be called, if the
+  removal happened during observer execution.
+
+* zend_get_internal_function_extension_handle[s]() must now be used over
+  zend_get_op_array_extension_handle[s]() when registering run_time_cache slots
+  for internal functions. If you need a cache slot for both internal and user
+  functions, you may obtain a slot for each through the corresponding function.
+
+* zend_is_true now returns bool rather than int. Note that on PHP 8 this has
+  always returned 0 or 1, so conversion should be trivial.
+
+* Added zend_hash_get_current_pos_ex() variant of zend_hash_get_current_pos().
+
+* Renamed rebuild_object_properties() to rebuild_object_properties_internal().
+  This function should not be used outside of zend_std_get_properties_ex() and
+  zend_std_get_properties(). Use zend_std_get_properties_ex() or
+  zend_std_get_properties() instead.
+
+* zend_object.properties must not be accessed directly. Use
+  zend_std_get_properties_ex() instead.
+
+* Removed IS_STATIC_VAR_UNINITIALIZED constant. Check for IS_NULL in the
+  static_variables array instead.
+
+* Removed ZEND_DIM_ALTERNATIVE_SYNTAX constant. This syntax no longer has a
+  specialized error message.

+     PGSQL_LIBS environment variables. When a directory argument is provided to
+     configure options (--with-pgsql=DIR or --with-pdo-pgsql=DIR), it will be
+     used instead of the pkg-config search.
+   - Added pkg-config support to find unixODBC and iODBC for the pdo_odbc
+     extension.
+   - Added pkg-config support to find GNU MP library. As a fallback default
+     system paths are searched. When a directory argument is provided
+     (--with-gmp=DIR), it will be used instead of the pkg-config.
+   - Added optional pkg-config support to find NET-SNMP library. As a fallback
+     net-snmp-config utility is used like before.
+   - Removed BC enable_pear variable check due to --enable-pear configure option
+     once used (use with_pear variable name).
+   - Cache variables synced to php_cv_* naming scheme. If you use them for

+ c. Windows build system changes
+   - The configure options --with-oci8-11g, --with-oci8-12c, --with-oci8-19,
+     --enable-apache2-2handler have been removed.
+   - The configure option --enable-apache2-4handler is now an alias for the

 ========================
 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.
+ a. ext/dom
+   - dom_read_t and dom_write_t now expect the function to return zend_result
+     instead of int.
+   - The macros DOM_NO_ARGS() and DOM_NOT_IMPLEMENTED() have been removed.
+   - New public APIs are available to handle callbacks from XPath, see
+     xpath_callbacks.h.
+   - Added public APIs to manipulate namespace data, see namespace_compat.h.
+   - php_dom_create_object() now no longer accepts a NULL obj argument.
+   - Removed the `ret` argument from the DOM_RET_OBJ macro, use the return
+     value instead.
+   - Removed DOM_XMLNS_NAMESPACE from xml_common.h. Use DOM_XMLNS_NS_URI
+     from namespace_compat.h instead.
+   - Added php_dom_get_ns_mapper(), php_dom_next_in_tree_order(),
+     php_dom_follow_spec_doc_ref(), and php_dom_follow_spec_doc_ref().
 
-- 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.
+ b. ext/random
+   - The macro RAND_RANGE_BADSCALING() has been removed. The implementation
+     should either be inlined and undefined behavior fixed or it should be
+     replaced by a non-biased scaler.
+   - The php_srand() and php_rand() functions have been removed. These were
+     slim wrappers around the corresponding php_mt_srand() and php_mt_rand()
+     function since PHP 7.1, but using zend_long instead of uint32_t as their
+     input/output types. This made their behavior incompatible between 32-bit
+     and 64-bit builds of PHP. Users of these functions are encouraged to
+     migrate to one of the more modern engines provided since PHP 8.2. If that
+     is not possible, due to backwards compatibility requirements, then the
+     php_mt_srand() and php_mt_rand() functions should be called directly and
+     the values appropriately casted.
+   - The PHP_RAND_MAX and RAND_MAX constants corresponding to the removed
+     php_rand() have also been removed.
+   - The generate member of a php_random_algo is now expected to return
+     the new php_random_result struct, replacing the last_generated_size
+     member of the php_random_status struct and the generate_size member of
+     the php_random_algo struct.
+   - The php_random_status struct has been removed, since the previous change
+     reduced it to a single void* member containing the actual state, resulting
+     in needless indirection. Functions taking a php_random_algo struct pointer
+     and a php_random_status struct pointer as separate parameters now take a
+     single php_random_algo_with_state struct by value, making it easier to
+     pass around the state with its associated algorithm and thus reducing
+     the chance for mistakes.
+   - The seed member of a php_random_algo has been removed. As a replacement
+     engine-specific seeding functions are now exposed. This change allows
+     users to better take engine-specific behavior into account. As an example
+     Mt19937 ignored the upper half of the seed parameter of the generic
+     seeding function.
+   - The CSPRNG API (php_random_(bytes|int)_*) is now provided by the new
+     and much smaller php_random_csprng.h header. The new header is included
+     in php_random.h for compatibility with existing users.
+   - A new php_random_generate_fallback_seed() function has been added as a
+     replacement for the generically named GENERATE_SEED(). The internal
+     implementation has been improved to generate better seeds, however any
+     users should use the opportunity to verify that seeding is first
+     attempted using the CSPRNG for better output size flexibility.
+   - The standalone combined_lcg engine has been removed, as the lcg_value()
+     userland function is deprecated and as the engine is unable to return
+     unbiased integer values. The internal php_combined_lcg() function remains
+     available for now.
 
-- ext/libxml
-  . The refcount APIs now return an `unsigned int` instead of an `int`.
-  . Removed php_libxml_xmlCheckUTF8(). Use xmlCheckUTF8() from libxml instead.
+ c. ext/xsl
+   - The function php_xsl_create_object() was removed as it was not used
+     nor exported.
 
-- 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.
+ d. ext/libxml
+   - Added php_libxml_pretend_ctx_error_ex() to emit errors as if they had come
+     from libxml.
+   - Added php_libxml_error_handler_va() to pass libxml errors, and
+     corresponding php_libxml_error_level enum.
+   - Removed the "properties" HashTable field from php_libxml_node_object.
+   - Added a way to attached private data to a php_libxml_ref_obj.
+   - Added a way to fix a class type onto php_libxml_ref_obj.
+   - Added a way to record quirks mode in php_libxml_ref_obj.
+   - Added php_libxml_uses_internal_errors().
+   - Added a way to override document handlers (e.g. serialization) with
+     php_libxml_document_handlers.
+   - Changed the refcount fields from int to unsigned int.
 
-- ext/standard
-  . Added php_url_decode_ex() and php_raw_url_decode_ex() that unlike their
-    non-ex counterparts do not work in-place.
-  . The php_std_date() function has been removed. Use php_format_date() with
-    the "D, d M Y H:i:s \\G\\M\\T" format instead.
-  . Added php_url_encode_to_smart_str() to encode a URL to a smart_str buffer.
-  . The functionality of getimagesize(), image_type_to_mime_type(),
-    and image_type_to_extension() is now extensible using the internal APIs
-    php_image_register_handler() and php_image_unregister_handler() in
-    php_image.h.
+ e. ext/date
+   - Added the php_format_date_ex() API to format instances of php_date_obj.
+   - Added the php_date_initialize_from_ts_long() and
+     php_date_initialize_from_ts_double() to initialize a php_date_obj with
+     the given unix timestamp using GMT +00:00.
+
+ f. ext/pcre
+   - php_pcre_match_impl() now no longer has a use_flags argument.
+     When flags should be ignored, pass 0 to the flags argument.
+   - php_pcre_match_impl() and pcre_get_compiled_regex_cache_ex() now use
+     proper boolean argument types instead of integer types.
+   - pcre_get_compiled_regex_cache_ex() now provides an option to collect extra
+     options (from modifiers used in the expression, for example), and calls
+     pcre2_set_compile_extra_options() with those options.
+   - Removed per-request cache, the cache is now always per process or
+     per thread depending on whether you use NTS or ZTS.
+     This was removed due to fundamental ordering issues between destructors.
+
+ g. ext/standard
+   - Added the php_base64_encode_ex() API with flag parameters, value can be
+     PHP_BASE64_NO_PADDING to encode without the padding character '='.
+   - The php_escape_shell_cmd() now takes a zend_string* instead of a char*
+     Moreover, providing it with a binary safe string is the responsibility of
+     the caller now.
+   - The php_escape_shell_arg() now takes a zend_string* instead of a char*
+     Moreover, providing it with a binary safe string is the responsibility of
+     the caller now.
+   - The php_info_html_esc() function has been removed, use
+     php_escape_html_entities() with ENT_QUOTES directly instead.
+   - The deprecated php_uint32 and php_int32 typedefs have been removed from
+     ext/standard/basic_functions.h. Use the standard uint32_t and int32_t
+     types instead.
+   - The php_mkdir() and php_mkdir_ex() APIs have been removed, use
+     php_stream_mkdir() instead.
+   - The php_strtoupper(), php_string_toupper(), php_strtolower(), and
+     php_string_tolower() functions has been removed, use zend_str_toupper(),
+     zend_string_toupper(), zend_str_tolower(), and zend_string_tolower()
+     respectively instead.
+   - The php_replace_controlchars_ex() function is no longer exposed.
+
+ h. ext/session
+   - Added the php_get_session_status() API to get the session status, which is
+     equivalent to reading PS(session_status) but works with shared objects too.
+   - Added the php_get_session_var_str() API to set a session variable without
+     needing to create a zend_string.
+   - The ext/session/php_session.h doesn't transitively include the
+     ext/hash/php_hash.h header anymore.
+   - It is no longer allowed to return out of the PS_ENCODE_LOOP macro.
+     Instead, you should break out of the loop instead.
+
+ i. ext/xml
+   - Made the expat compatibility wrapper XML_GetCurrentByteIndex return a long
+     instead of an int. This corresponds to the XML_Index type when
+     XML_LARGE_SIZE is not used in expat.
 
 ========================
 4. OpCode changes
 ========================
 
-* New ZEND_DECLARE_ATTRIBUTED_CONST is used when a global constant is declared
-  with `const` and has attributes; this opcode is used *instead* of the
-  ZEND_DECLARE_CONST, and in addition to the name of the constant and the
-  value to use, has a ZEND_OP_DATA with a pointer to the compiled attributes.
+* DO_ICALL, DO_FCALL, and DO_FCALL_BY_NAME now call zend_interrupt_function
+  while the internal frame is still on the stack. This means interrupt handlers
+  will now see the internal call. If your interrupt handler does something like
+  switching EG(current_execute_data), it should not do so if an internal func
+  is on top.
+* New FRAMELESS_ICALL_[0,3] opcodes for faster internal function calls have been
+  added. These opcodes don't create a stack frame, but pass arguments via opcode
+  operands. They only work for functions that are known at compile-time, and
+  that provide a frameless handler (search for usages of the
+  ZEND_FRAMELESS_FUNCTION macro).
+
+* CREATE_GENERATOR now initializes the generator with opline pointing to the
+  CREATE_GENERATOR op (before, opline was set to the next op).
+
+* YIELD and YIELD_FROM do not increment the opline anymore.
+
+* The EXIT opcode has been removed as exit is now implemented as a function.
 
 ========================
 5. SAPI changes
 ========================
-
-- SAPIs must now call php_child_init() after a fork. If php-src code was
-  executed in other threads than the one initiating the fork,
-  refresh_memory_manager() must be called in every such thread.
