and to use iter_swap() for value swapping.
- Added support for creating or initializing a task_arena instance that
is connected to the arena currently used by the thread.
- graph/binpack example modified to use multifunction_node.
- For performance analysis, use Intel(R) VTune(TM) Amplifier XE 2015
and higher; older versions are no longer supported.
- Improved support for compilation with disabled RTTI, by omitting its use
in auxiliary code, such as assertions. However some functionality,
particularly the flow graph, does not work if RTTI is disabled.
- The tachyon example for Android* can be built using Android Studio 1.5
and higher with experimental Gradle plugin 0.4.0.
Preview Features:
- Added class opencl_subbufer that allows using OpenCL* sub-buffer

Changes (w.r.t. Intel TBB 4.4 Update 1):
- Improved interoperability with Intel(R) OpenMP RTL (libiomp) on Linux:
OpenMP affinity settings do not affect the default number of threads
used in the task scheduler. Intel(R) C++ Compiler 16.0 Update 1
or later is required.
- Added a new flow graph example with different implementations of the
Cholesky Factorization algorithm.
Preview Features:
- Added template class opencl_node to the flow graph API. It allows a
flow graph to offload computations to OpenCL* devices.

the API of the node by obtaining message keys via functions
associated with the message type (instead of node ports).
- Added static_partitioner that minimizes overhead of parallel_for and
parallel_reduce for well-balanced workloads.
- Improved template class async_node in the flow graph API to support
user settable concurrency limits.
Bugs fixed:
- Fixed a possible crash in the GUI layer for library examples on Linux.
------------------------------------------------------------------------
Intel TBB 4.4 Update 1
TBB_INTERFACE_VERSION == 9001
Changes (w.r.t. Intel TBB 4.4):
- Added support for Microsoft* Visual Studio* 2015.

functions for Microsoft Visual Studio 2005 and earlier versions.
- For GCC 4.7 and higher, the intrinsics-based platform isolation layer
uses __atomic_* built-ins instead of the legacy __sync_* ones.
This change is inspired by a contribution from Mathieu Malaterre.
- Improvements in task_arena:
Several application threads may join a task_arena and execute tasks
simultaneously. The amount of concurrency reserved for application
threads at task_arena construction can be set to any value between
0 and the arena concurrency limit.
- The fractal example was modified to demonstrate class task_arena
and moved to examples/task_arena/fractal.
Bugs fixed:
- Fixed a deadlock during destruction of task_scheduler_init objects
when one of destructors is set to wait for worker threads.
- Added a workaround for a possible crash on OS X* when dynamic memory
allocator replacement (libtbbmalloc_proxy) is used and memory is
released during application startup.
- Usage of mutable functors with task_group::run_and_wait() and
task_arena::enqueue() is disabled. An attempt to pass a functor
which operator()() is not const will produce compilation errors.
- Makefiles and environment scripts now properly recognize GCC 5.0 and
higher.

libstdc++, specify stdlib=libstdc++ in the make command line.
Preview Features:
- Added a new example, graph/fgbzip2, that shows usage of
tbb::flow::async_node.
- Modification to the low-level API for memory pools:
added a function for finding a memory pool by an object allocated
from that pool.
- tbb::memory_pool now does not request memory till the first allocation
from the pool.
Changes affecting backward compatibility:
- Internal layout of flow graph nodes has changed; recompilation is
recommended for all binaries that use the flow graph.
- Resetting a tbb::flow::source_node will immediately activate it,
unless it was created in inactive state.
Bugs fixed:
- Failure at creation of a memory pool will not cause process
termination anymore.

Changes affecting backward compatibility:
- tbb::flow::graph has been modified to spawn its tasks;
the old behaviour (task enqueuing) is deprecated. This change may
impact applications that expected a flow graph to make progress
without calling wait_for_all(), which is no longer guaranteed. See
the documentation for more details.
- Changed the return values of the scalable_allocation_mode() function.
Bugs fixed:
- Fixed a leak of parallel_reduce body objects when execution is
cancelled or an exception is thrown, as suggested by Darcy Harrison.

Intel TBB 4.1 Update 2
TBB_INTERFACE_VERSION == 6102
Changes (w.r.t. Intel TBB 4.1 Update 1):
- Objects up to 128 MB are now cached by the tbbmalloc. Previously
the threshold was 8MB. Objects larger than 128 MB are still
processed by direct OS calls.
- concurrent_unordered_multiset and concurrent_unordered_multimap
have been added, based on Microsoft* PPL prototype.
- Ability to value-initialize a tbb::atomic<T> variable on construction
in C++11, with const expressions properly supported.
Community Preview Features:

for large object allocations.
- Fixed task_arena::enqueue() to use task_group_context of target arena.
- Improved implementation of 64 bit atomics on ia32.
------------------------------------------------------------------------
Intel TBB 4.1 Update 1
TBB_INTERFACE_VERSION == 6101
Changes (w.r.t. Intel TBB 4.1):
- concurrent_vector class now supports initialization/assignment
via C++11 initializer list feature (std::initializer_list<T>)
- Added implementation of the platform isolation layer based on
Intel compiler atomic built-ins; it is supposed to work on
any platform supported by compiler version 12.1 and newer.
- Using GetNativeSystemInfo() instead of GetSystemInfo() to support
more than 32 processors for 32-bit applications under WOW64.
- The following form of parallel_for:
parallel_for(first, last, [step,] f[, context]) now accepts an
optional partitioner parameter after the function f.
Backward-incompatible API changes:
- The library no longer injects tuple in to namespace std.
In previous releases, tuple was injected into namespace std by
flow_graph.h when std::tuple was not available. In this release,
flow_graph.h now uses tbb::flow::tuple. On platforms where
std::tuple is available, tbb::flow::tuple is typedef'ed to
std::tuple. On all other platforms, tbb::flow::tuple provides
a subset of the functionality defined by std::tuple. Users of
flow_graph.h may need to change their uses of std::tuple to
tbb::flow::tuple to ensure compatibility with non-C++11 compliant
compilers.
Bugs fixed:
- Fixed local observer to be able to override propagated CPU state and
to provide correct value of task_arena::current_slot() in callbacks.
------------------------------------------------------------------------

on Microsoft* Windows*.
- parallel_deterministic_reduce template function is fully supported.
- TBB headers can be used with C++0x/C++11 mode (-std=c++0x) of GCC
and Intel(R) Compiler.
- C++11 std::make_exception_ptr is used where available, instead of
std::copy_exception from earlier C++0x implementations.
- Improvements in the TBB allocator to reduce extra memory consumption.
- Partial refactoring of the task scheduler data structures.
- TBB examples allow more flexible specification of the thread number,
including arithmetic and geometric progression.
Bugs fixed:
- On Linux & OS X*, pre-built TBB binaries do not yet support exact
exception propagation via C++11 exception_ptr. To prevent run time
errors, by default TBB headers disable exact exception propagation
even if the C++ implementation provides exception_ptr.
Community Preview Features:
- Added: class task_arena, for work submission by multiple application
threads with thread-independent control of concurrency level.
- Added: task_scheduler_observer can be created as local to a master
thread, to observe threads that work on behalf of that master.
Local observers may have new on_scheduler_leaving() callback.
------------------------------------------------------------------------
Intel TBB 4.0 Update 5
TBB_INTERFACE_VERSION == 6005
Changes (w.r.t. Intel TBB 4.0 Update 4):
- Parallel pipeline optimization (directly storing small objects in the
interstage data buffers) limited to trivially-copyable types for
C++11 and a short list of types for earlier compilers.
- _VARIADIC_MAX switch is honored for TBB tuple implementation
and flow::graph nodes based on tuple.
- Support of Cocoa framework was added to the GUI examples on OS X*
systems.
Bugs fixed:
- Fixed a tv_nsec overflow bug in condition_variable::wait_for.
- Fixed execution order of enqueued tasks with different priorities.
- Fixed a bug with task priority changes causing lack of progress
for fire-and-forget tasks when TBB was initialized to use 1 thread.
- Fixed duplicate symbol problem when linking multiple compilation
units that include flow_graph.h on VC 10.
------------------------------------------------------------------------
Intel TBB 4.0 Update 4
TBB_INTERFACE_VERSION == 6004
Changes (w.r.t. Intel TBB 4.0 Update 3):
- The TBB memory allocator transparently supports large pages on Linux.
- A new flow_graph example, logic_sim, was added.
- Support for DirectX* 9 was added to GUI examples.
Community Preview Features:
- Added: aggregator, a new concurrency control mechanism.
Bugs fixed:
- The abort operation on concurrent_bounded_queue now leaves the queue
in a reusable state. If a bad_alloc or bad_last_alloc exception is
thrown while the queue is recovering from an abort, that exception
will be reported instead of user_abort on the thread on which it
occurred, and the queue will not be reusable.
- Steal limiting heuristic fixed to avoid premature stealing disabling
when large amount of __thread data is allocated on thread stack.
- Fixed a low-probability leak of arenas in the task scheduler.
- In STL-compatible allocator classes, the method construct() was fixed
to comply with C++11 requirements.
- Fixed a bug that prevented creation of fixed-size memory pools
smaller than 2M.
- Significantly reduced the amount of warnings from various compilers.
Open-source contributions integrated:
- Multiple improvements by Raf Schietekat.
- Basic support for Clang on OS X* by Blas Rodriguez Somoza.
- Fixes for warnings and corner-case bugs by Blas Rodriguez Somoza
and Edward Lam.
------------------------------------------------------------------------
Intel TBB 4.0 Update 3
TBB_INTERFACE_VERSION == 6003
Changes (w.r.t. Intel TBB 4.0 Update 2):
- Modifications to the low-level API for memory pools:
added support for aligned allocations;
pool policies reworked to allow backward-compatible extensions;
added a policy to not return memory space till destruction;
pool_reset() does not return memory space anymore.
- Class tbb::flow::graph_iterator added to iterate over all nodes
registered with a graph instance.
- multioutput_function_node has been renamed multifunction_node.
multifunction_node and split_node are now fully-supported features.
- For the tagged join node, the policy for try_put of an item with
already existing tag has been defined: the item will be rejected.
- Matching the behavior on Windows, on other platforms the optional
shared libraries (libtbbmalloc, libirml) now are also searched
only in the directory where libtbb is located.
- The platform isolation layer based on GCC built-ins is extended.
Backward-incompatible API changes:
- a graph reference parameter is now required to be passed to the
constructors of the following flow graph nodes: overwrite_node,
write_once_node, broadcast_node, and the CPF or_node.
- the following tbb::flow node methods and typedefs have been renamed:
Old New
join_node and or_node:
inputs() -> input_ports()
input_ports_tuple_type -> input_ports_type
multifunction_node and split_node:
ports_type -> output_ports_type
Bugs fixed:
- Not all logical processors were utilized on systems with more than
64 cores split by Windows into several processor groups.
------------------------------------------------------------------------
Intel TBB 4.0 Update 2 commercial-aligned release
TBB_INTERFACE_VERSION == 6002
Changes (w.r.t. Intel TBB 4.0 Update 1 commercial-aligned release):
- concurrent_bounded_queue now has an abort() operation that releases
threads involved in pending push or pop operations. The released
threads will receive a tbb::user_abort exception.
- Added Community Preview Feature: concurrent_lru_cache container,
a concurrent implementation of LRU (least-recently-used) cache.
Bugs fixed:
- fixed a race condition in the TBB scalable allocator.
- concurrent_queue counter wraparound bug was fixed, which occurred when
the number of push and pop operations exceeded ~>4 billion on IA32.
- fixed races in the TBB scheduler that could put workers asleep too
early, especially in presence of affinitized tasks.
------------------------------------------------------------------------
Intel TBB 4.0 Update 1 commercial-aligned release
TBB_INTERFACE_VERSION == 6000 (forgotten to increment)
Changes (w.r.t. Intel TBB 4.0 commercial-aligned release):
- Memory leaks fixed in binpack example.
- Improvements and fixes in the TBB allocator.
------------------------------------------------------------------------
Intel TBB 4.0 commercial-aligned release
TBB_INTERFACE_VERSION == 6000
Changes (w.r.t. Intel TBB 3.0 Update 8 commercial-aligned release):
- concurrent_priority_queue is now a fully supported feature.
Capacity control methods were removed.
- Flow graph is now a fully supported feature.
- A new memory backend has been implemented in the TBB allocator.
It can reuse freed memory for both small and large objects, and
returns unused memory blocks to the OS more actively.
- Improved partitioning algorithms for parallel_for and parallel_reduce
to better handle load imbalance.
- The convex_hull example has been refactored for reproducible
performance results.
- The major interface version has changed from 5 to 6.
Deprecated interfaces might be removed in future releases.
Community Preview Features:
- Added: serial subset, i.e. sequential implementations of TBB generic
algorithms (currently, only provided for parallel_for).
- Preview of new flow graph nodes:
or_node (accepts multiple inputs, forwards each input separately
to all successors),
split_node (accepts tuples, and forwards each element of a tuple
to a corresponding successor), and
multioutput_function_node (accepts one input, and passes the input
and a tuple of output ports to the function body to support outputs
to multiple successors).
- Added: memory pools for more control on memory source, grouping,
and collective deallocation.
------------------------------------------------------------------------
Intel TBB 3.0 Update 8 commercial-aligned release
TBB_INTERFACE_VERSION == 5008
Changes (w.r.t. Intel TBB 3.0 Update 7 commercial-aligned release):
- Task priorities become an official feature of TBB,
not community preview as before.
- Atomics API extended, and implementation refactored.
- Added task::set_parent() method.
- Added concurrent_unordered_set container.
Open-source contributions integrated:
- PowerPC support by Raf Schietekat.

as well as to set directories for the library search.
- parallel_deterministic_reduce template function was added.
------------------------------------------------------------------------
Intel TBB 3.0 Update 7 commercial-aligned release
TBB_INTERFACE_VERSION == 5006 (forgotten to increment)
Changes (w.r.t. Intel TBB 3.0 Update 6 commercial-aligned release):
- Added implementation of the platform isolation layer based on
GCC atomic built-ins; it is supposed to work on any platform
where GCC has these built-ins.
Community Preview Features:
