Release Notes: A bug has been removed from File::deleteALL, in which the validation regexp was not used well.
Release Notes: WATemplate has been modified to support traversable/array access metaelement objects (which are not necessarily arrays). The metaElements method is now strict by default, and the compiler has been modified to support elements without space. The shared memory access class now uses semaphores to avoid memory access conflicts. Minor bugs have been fixed.
Release Notes: WAObject has been modified to be executed without warnings on PHP 5.4.
Release Notes: The FastObjectSource, LanguageSource, and TemplateSource objects have been modified to clean and delete the cache and the AFO if the origin has disappeared (is deleted).
Release Notes: The WATemplate syntax analyzer no longer uses urlencode and urldecode, greatly improving compilation time. An error has been corrected in the regular expressions of the templates compiler: sometimes the subtemplate was not correctly replaced.
Release Notes: The WATemplate class has been corrected so the subtemplate IDs can be only only letters, digits, or the special characters ".", "-", "_", and "|".
