 1. Internal API changes
 ========================
 
+	a. virtual_file_ex
+
 virtual_file_ex takes now a TSRM context as last parameter:
 CWD_API int virtual_file_ex(cwd_state *state, const char *path, 
  verify_path_func verify_path, int use_realpath TSRLS_DC);
+
+	b. stat/lstat support
+
+php_sys_lstat is now available on all platforms. On unix-like platform
+php_sys_lstat is an alias to lstat (when avaible). On Windows it is now 
+available using php_sys_lstat. php_sys_stat and php_sys_lstat usage is recommended 
+instead of calling lstat directly, to ensure portability.
