## RcppParallel 5.1.6
* Patch for TBB to allow compilation with gcc-13.
* Fixed a memory leak that could occur when using TinyThread on POSIX systems.
(#185; @dipertix and and @kevinushey)
## RcppParallel 5.1.5
* Patches to ensure compatibility with the R 4.2.0 UCRT toolchain on Windows,
adapted from patches contributed by Tomas Kalibera.
* Fixed an issue where setting `TBB_ROOT` (or `TBB_INC` / `TBB_LIB`) would
copy rather than symlink the associated libraries. (#161)
## RcppParallel 5.1.4
* Fixed an issue causing client packages of RcppParallel to fail to compile
on Solaris.
## RcppParallel 5.1.3
* Fixed an issue that prevented compilation of RcppParallel with R (< 4.0.0)
of R on Windows.
* The `RCPP_PARALLEL_USE_TBBMALLOC_PROXY` environment variable can now be used
to control whether RcppParallel loads the `tbbmalloc_proxy` library on load.
See https://www.threadingbuildingblocks.org/docs/help/tbb_userguide/Automically_Replacing_malloc.html
for more information.
## RcppParallel 5.1.2
* `RcppParallel` gains the `tbbLibraryPath()` function, to be used when attempting
to query the location of the TBB libraries that `RcppParallel` has been
configured to use. This may be useful for R packages which wish to explicitly
use, or link to, these libraries.
## RcppParallel 5.1.1
* Updated bundled version of TBB (Intel TBB 2019 Update 8).
* RcppParallel can now be configured to use an external copy of TBB, via the
`TBB_LIB` and `TBB_INC` environment variables. These should be set to the
directories containing the TBB libraries and headers, respectively.
* Added support for the latest versions of Intel oneAPI TBB / oneTBB.
* Updated TBB functionality for the new interface.
* Falling back to building TBB from local source code.
* Backward TBB compatibility based on `__TBB_tbb_stddef_H`.
* Resolved conflicts between system and local TBB headers.
* Fixed URLs, used HTTPS, and minor cleanups.
* Updated package DESCRIPTION and bumped version.
* `setThreadOptions(...)` can again be called multiple times per session.
The requested number of threads will be used for invocations to `parallelFor()`
and `parallelReduce()` that don't explicitly request a specific number of threads.
* The `parallelFor()` and `parallelReduce()` functions gain the `numThreads`
argument, allowing one to limit the number of threads used for a
particular computation.
## RcppParallel 5.0.3
* Fixed compilation on macOS M1 machines.
## RcppParallel 5.0.2
* `setThreadOptions(...)` can now only be called once per session, to avoid
segfaults when compiling RcppParallel / TBB with gcc 10.1. Subsequent
calls to `setThreadOptions(...)` are ignored.
## RcppParallel 5.0.1
* Fixed compilation issue on OpenSUSE Tumbleweed with -flto=auto
* Fixed compilation when CPPFLAGS = -I/usr/local/include and a version
of libtbb is installed there
## RcppParallel 5.0.0
* RcppParallel backend can now be customized with RCPP_PARALLEL_BACKEND
environment variable (supported values are 'tbb' and 'tinythread')
* Fixed issue when compiling RcppParallel on macOS Catalina
* Fixed issue when compiling RcppParallel with Rtools40
## RcppParallel 4.4.4
* Fixed an issue when compiling RcppParallel with clang-9 on Fedora
## RcppParallel 4.4.3
* Suppress gcc-9 warnings related -Wclass-memaccess
* Added TBB headers for serial TBB operations (#90, @mikejiang)
* Fixed row iterator constructor (#87, @wtianyi)
* Fixed compilation on FreeBSD
## RcppParallel 4.4.2
* Suppress gcc-8 warnings related to -Wclass-memaccess
* Use PKG_CXXFLAGS rather than PKG_CPPFLAGS
* Remove unused dependency on the BH package
## RcppParallel 4.4.1
* Ensure user-specified R configuration passed to TBB
* Work around warnings emitted by gcc 8
## RcppParallel 4.4.0
* Respect user-defined compiler settings (e.g. from ~/.R/Makevars).
* Remove TBB's attempts to suppress compiler diagnostics.
* Allow setting the number of threads to use via RCPP_PARALLEL_NUM_THREADS
environment variable.
* Update to TBB 2018 Update 1.
* Add native registration of compiled functions.
## RcppParallel 4.3.20
* Add support for Rtools 3.3 w/ GCC 4.9
## RcppParallel 4.3.14
* Add support for TBB on Solaris
* Fix failure to compile on OS X Snow Leopard R toolchain
* Add const and non-const operator[] for RMatrix class
## RcppParallel 4.3.8
* Add tbbmalloc library
* Correctly pass clang to TBB configure when R is using clang
## RcppParallel 4.3.6
* Support for TBB on Windows
## RcppParallel 4.3.3
* Update to TBB 4.3 (fixes clang compilation error in platform.h)
* Forward CXX to TBB Makefile
## RcppParallel 4.2.5
* Initial release
