Created defines for MTAPI version
-
Added missing fields in mtapi_info_t structure, in particular organization ID
-
Changed reporting of number of domains and nodes to "unlimited"
-
Changed group deleted and task state attributes to atomic
-
Enabled reuse of main thread, which is configurable via node attributes
-
Set result to MTAPI_NULL on error in mtapi_group_wait_any
-
Network plugin:
-
Disabled adress reuse for listening socket
-
Solved problem with port reuse on Linux
-
Set values to zero on failure for buffer pop operations

-
Added check for cycles in graph
-
Added default token count to network
-
Changed internal exceptions to assertions
-
Changed return type of operator >> to allow for connection chains
-
Changed semantics of source process (emit tokens only if function returns true)
-
Changed initalization so that the number of slices can now be set at runtime
-
Added automatic computation of maximum number of slices
-
Changed done sync to atomics
-
Removed Network::Make for simpler usage
-
Added Network:IsValid to check network for errors
*
Containers:
-
Added missing PT_ASSERT calls in hazard pointer test
