   zend_logo_guid() have been removed

+- extensions can't override zend_execute() any more, they should override
+  zend_execute_ex() instead. The EG(current_execute_data) is already
+  initialized in zend_execute_ex(), so for compatibility extensions
+  may need to use EG(current_execute_data)->prev_execute_data instead.
+- removed EG(arg_types_stack), EX(fbc), EX(called_scope), EX(current_object)
+- added op_array->nested_calls. It's calculated at compile time.
+- added EX(call_slots). It is an array to store information about syntaticaly
+  nested calls (e.g. foo(bar())). It's preallocated together with execute_data.
+- added EX(call) - pointer to a current calling function. Actually an
+  element of EX(call_slots)
+- opcodes INIT_METHOD_CALL, ZEND_INIT_STATIC_METHOD_CALL,
+  ZEND_INIT_FCALL_BY_NAME, ZEND_INIT_NS_FCALL_BY_NAME use result.num as
+  an index in EX(call_slots)
+- opcode ZEND_NEW uses extended_vallue as an index in EX(call_slots)
+- opcoes ZEND_DO_FCALL and ZEND_DO_FCALL_BY_NAME use op2.num as
+  an index in EX(call_slots)
+- added op_array->used_stack. It's calculated at compile time and the
+  corresponding stack space is preallocated together with execute_data.
+  ZEND_SEND* and ZEND_DO_FCALL* don't need to check for stack overflow
+  anymore.
+- Removed execute_data->Ts field. The VM temporary variables always allocated
+  immediately before execute_data structure. Now they are accessed by offset
+  from the execute_data base pointer (instead of execute_data->Ts). Compiler
+  stores new offsets in op_array->opcodes[*].op?.num. You can use macros
+  EX_TMP_VAR() and EX_TMP_VAR_NUM() to access temp_variable by offset or
+  number. You can convert number to offset using EX_TMP_VAR_NUM(0, num) or
+  offset to number (EX_TMP_VAR_NUM(0,0)-EX_TMP_VAR(0,offset)).
+- Removed execute_data->CVs field. The VM compiled variables always allocated
+  immediately after execute_data structure. Now they are accessed by offset
+  from the execute_data base pointer (instead of execute_data->CVs). You can
+  use macros EX_CV_NUM() to access compiled variables by number.

 3. Deprecated Functionality
 ========================================
 
+- The original MySQL extension is now deprecated, and will generate deprecation
+  warnings when connecting to a database through mysql_connect(),
+  mysql_pconnect() or by establishing an implicit connection. Use MySQLi or PDO
+  instead.
 - The preg_replace /e modifier is now deprecated.  Use
   preg_replace_callback instead.
   (https://wiki.php.net/rfc/remove_preg_replace_eval_modifier)
+- IntlDateFormatter::setTimeZoneID() and datefmt_set_timezone_id() are
+  deprecated. Use IntlDateFormatter::setTimeZone() or datefmt_set_timezone()
+  instead.
+- mcrypt_ecb(), mcrypt_cbc(), mcrypt_cfb() and mcrypt_ofb() now throw
+  E_DEPRECATED. Their use was already previously discouraged in the docs,
+  but that predated the existence of E_DEPRECATED.
