Since v.5.5.13 namespace so_5::rt is deprecated. It now contains only several typedefs for compatibility with previous versions. All the stuff from so_5::rt is moved into so_5 namespace.

There are almost no changes in names during moving content from so_5::rt to so_5, except the following cases:

so_5::coop_t must be used instead of so_5::rt::agent_coop_t;
so_5::coop_unique_ptr_t must be used instead of so_5::rt::agent_coop_unique_ptr_t;
so_5::layer_t must be used instead of so_5::rt::so_layer_t (there are also new names: so_5::layer_unique_ptr_t, so_5::layer_ref_t and so_5::layer_map_t instead of so_5::rt::so_layer_unique_ptr_t, so_5::rt::so_layer_ref_t, so_5::rt::so_layer_map_t).

Namespace so_5::rt will be removed from SObjectizer in v.5.6.0. It means that code which uses SObjectizer must be modified. In most cases modification will be very simple: a change of so_5::rt prefix to so_5 prefix.

Attention: Some code cannot be compiled after switching to v.5.5.13 if the following instructions are used together:
using namespace so_5;
using namespace so_5::rt;
It is because the same names (like agent_t) are now defined in both namespaces. It this case using namespace so_5::rt must be removed.
