@ -104,10 +104,10 @@ Removed Functionality
Deprecated Functionality
------------------------
- The ``Func::Call(val_list*, ...)`` method is now deprecated. The alternate
overload taking a ``zeek::Args`` (``std::vector<IntrusivePtr<Val>>``) should
be used instead. There's also now a variadic template that forwards all
arguments.
- The ``Func::Call(val_list*, ...)`` method is now deprecated. Use operator()
instead which takes a ``zeek::Args`` (``std::vector<IntrusivePtr<Val>>``).
There's also a variadic template for operator() that forwards all arguments
into a ``zeek::Args`` for you.
- The ``EventMgr::QueueEvent()`` and EventMgr::QueueEventFast()`` methods
are now deprecated, use ``EventMgr::Enqueue()`` instead.
