Intel TBB 2019 Update 6
6+
TBB_INTERFACE_VERSION == 11006
7+
8+
Changes (w.r.t. Intel TBB 2019 Update 5):
9+
10+
- Added support for Microsoft* Visual Studio* 2019.
11+
- Added support for enqueuing tbb::task into tbb::task_arena
12+
(https://github.com/01org/tbb/issues/116).
13+
- Improved support for allocator propagation on concurrent_hash_map
14+
assigning and swapping.
15+
- Improved scalable_allocation_command cleanup operations to release
16+
more memory buffered by the calling thread.
17+
- Separated allocation of small and large objects into distinct memory
18+
regions, which helps to reduce excessive memory caching inside the
19+
TBB allocator.
20+
21+
Preview Features:
22+
23+
- Removed template class gfx_factory from the flow graph API.

TBB_INTERFACE_VERSION == 11005
28+
29+
Changes (w.r.t. Intel TBB 2019 Update 4):
30+
31+
- Associating a task_scheduler_observer with an implicit or explicit
32+
task arena is now a fully supported feature.
33+
- Added a CMake module TBBInstallConfig that allows to generate and
34+
install CMake configuration files for TBB packages.
35+
Inspired by Hans Johnson (https://github.com/01org/tbb/pull/119).
36+
- Added node handles, methods merge() and unsafe_extract() to concurrent
37+
unordered containers.
38+
- Added constructors with Compare argument to concurrent_priority_queue
39+
(https://github.com/01org/tbb/issues/109).
40+
- Controlling the stack size of worker threads is now supported for
41+
Universal Windows Platform.
42+
- Improved tbb::zip_iterator to work with algorithms that swap values
43+
via iterators.
44+
- Improved support for user-specified allocators in concurrent_hash_map,
45+
including construction of allocator-aware data types.
46+
- For ReaderWriterMutex types, upgrades and downgrades now succeed if
47+
the mutex is already in the requested state.
48+
Inspired by Niadb (https://github.com/01org/tbb/pull/122).
49+
50+
Preview Features:
51+
52+
- The task_scheduler_observer::may_sleep() method has been removed.
53+
54+
Bugs fixed:
55+
56+
- Fixed the issue with a pipeline parallel filter executing serially if
57+
it follows a thread-bound filter.
58+
- Fixed a performance regression observed when multiple parallel
59+
algorithms start simultaneously.

Changes (w.r.t. Intel TBB 2019 Update 3):
66+
67+
- global_control class is now a fully supported feature.
68+
- Added deduction guides for tbb containers: concurrent_hash_map,
69+
concurrent_unordered_map, concurrent_unordered_set.
70+
- Added tbb::scalable_memory_resource function returning
71+
std::pmr::memory_resource interface to the TBB memory allocator.
72+
- Added tbb::cache_aligned_resource class that implements
73+
std::pmr::memory_resource with cache alignment and no false sharing.
74+
- Added rml::pool_msize function returning the usable size of a memory
75+
block allocated from a given memory pool.
76+
- Added default and copy constructors for tbb::counting_iterator
77+
and tbb::zip_iterator.
78+
- Added TBB_malloc_replacement_log function to obtain the status of
79+
dynamic memory allocation replacement (Windows* only).
80+
- CMake configuration file now supports release-only and debug-only
81+
configurations (https://github.com/01org/tbb/issues/113).
