Exceptions raised in templates were previously wrapped in TemplateSyntaxError (in TEMPLATE_DEBUG mode only) in order to provide template source details on the debug 500 page. The same debug information is now provided by annotating exceptions rather than wrapping them. This makes catching exceptions raised from templates more sane, as it's consistent in or out of DEBUG, and you can catch the specific exception(s) you care about rather than having to also catch TemplateSyntaxError and unwrap it. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16833 bcc190cf-cafb-0310-a4f2-bffc1f526a37
