## Version history
### v5.1.0 (2026-01-03)
* New/changed features:
* Added `detach_bulk()` and `submit_bulk()` member functions to submit tasks in bulk. You can pass either a range of iterators or a container. The mutex protecting the task queue is locked only once for the entire bulk submission, which should improve performance when submitting a large number of tasks; if the tasks were submitted using individual calls to `detach_task()` or `submit_task()` instead, the mutex would need to be locked and unlocked for each task.
* `detach_blocks()`/`detach_loop()`/`detach_sequence()` and `submit_blocks()`/`submit_loop()`/`submit_sequence()` now use `detach_bulk()` and `submit_bulk()`, respectively, under the hood for increased performance (the API remains the same). They have also been refactored using helper functions and custom function object classes to reduce code duplication.
* All `submit_*` member functions now use a C++17/20 polyfill for `std::move_only_function` when C++23 is not available (or when using libc++, which at the time of this release has not implemented it yet). This allows them to work without using `std::shared_ptr`, which should increase performance.
* If the native extensions are enabled, a pool created with the default constructor will now only use the number of threads available to the process, as obtained from `BS::get_os_process_affinity()`, which can be less than the number of hardware threads. See [#161](https://github.com/bshoshany/thread-pool/issues/161).
* Since importing the C++ Standard Library using `import std` is now supported by all 3 major compilers, the library (and test program) will now use `import std` whenever the macro `BS_THREAD_POOL_IMPORT_STD` is defined, as long as C++23 is enabled, without performing any additional checks for compiler or standard library support (aside from the workaround for GCC mentioned below).
* The `BS::tp` enumeration is now properly defined as an `enum class` with the appropriate bitwise operators.
* Removed the polyfills for `std::counting_semaphore` and `std::binary_semaphore` from `BS_thread_pool.hpp`, as they are not used by the library itself, to reduce the size of the header file. If you need them, you can copy them from the test program `BS_thread_pool_test.cpp`.
* On Windows, if the native extensions are enabled, `WIN32_LEAN_AND_MEAN` is now defined before including `<windows.h>` to reduce compilation time.
* Bug fixes:
* The system macros `major` and `minor` (from `<sys/sysmacros.h>` on Linux) or `min` and `max` (from `<windows.h>` on Windows) are now automatically undefined if they are detected, to prevent compilation errors. This was also done previously, but only under certain conditions; now it is done unconditionally, as some users reported issues. On Windows, `NOMINMAX` is now defined before including `<windows.h>`, but the `min` and `max` macros are still undefined independently.
* `BS::wait_deadlock` is now only exported by the module if exceptions are enabled, preventing a compiler error. See [#160](https://github.com/bshoshany/thread-pool/pull/160).
* Fixed a typo in `BS::thread_pool::submit_sequence()` which caused the wrong number of futures to be reserved, potentially resulting in unnecessary reallocations.
* `BS::multi_future<T>::wait_until` now correctly waits using the specific clock type passed in the template parameter.
* Fixed a bug where `reset()` failed to notify worker threads if the pool was unpaused before resetting.
* `get_os_thread_affinity()` and `set_os_thread_affinity()` now return `std::nullopt` and `false` (respectively) on Android, as the API is not supported. See [#163](https://github.com/bshoshany/thread-pool/pull/163).
* Tests:
* The test program `BS_thread_pool_test.cpp` now prints colored output for better readability. This can be disabled by setting the `NO_COLOR` environment variable.
* The test program now prints out the Mandelbrot set it generates, downsampled to fit in a terminal window (at 120 character width). This will be in 24-bit color in the terminal, and in monochrome using Unicode blocks in the log file. (If `NO_COLOR` is set, the terminal output will also be in monochrome.)
* The test program now looks for `default_args.txt` in both the current folder and the parent folder when reading default command line arguments.
* Documentation:
* Added an example in `README.md` for getting and setting process affinity.
* Removed the suggestion in `README.md` to use the `-pthread` flag on Linux/macOS, as it does not seem to be necessary in order to use the library, at least on the systems I tested with. If you are using a system that requires it, then you probably already know about it.
* Updated the instructions in `README.md` for compiling with GCC using `import BS.thread_pool`, and added instructions on how to compile the `std` module with GNU libstdc++.
* Fixed many typos and inconsistencies in `README.md`.
* Known issues:
* At the time of this release, there is a bug in Clang with libc++ where using `std::jthread` in a C++20 module causes a compilation error. As a workaround, until the bug is fixed, the thread pool library automatically falls back to `std::thread` if it detects that Clang and libc++ are being used together with C++20 modules. This workaround can be disabled by defining `BS_THREAD_POOL_DISABLE_WORKAROUNDS` when compiling the module.
* At the time of this release, there is a bug when using GCC with libstdc++ on Windows via MSYS2 where the `BS.thread_pool` module doesn't compile if both native extensions and `import std` are enabled. As a workaround, until the bug is fixed, the thread pool library automatically falls back to header files if it detects that GCC and libstdc++ are being used together with the C++23 `std` module on Windows. This workaround can be disabled by defining `BS_THREAD_POOL_DISABLE_WORKAROUNDS` when compiling the module.
* Development:
* The Python script I use for compiling the test program, `compile_cpp.py`, has received numerous improvements:
* The script now supports `import std` with GCC in addition to Clang and MSVC.
* The script now only recompiles the program if the source file(s), module(s), and optional additional dependencies (added using the flag `-n`/`--deps` or the `deps` field in `compile_cpp.yaml`) have changed since the binary was created. Use `-e`/`--force` to force recompilation.
* The script now allows disabling exceptions by either defining `disable_exceptions: true` in `compile_cpp.yaml` or using the flag `-x=true`/`--disable-exceptions=true` (the flag overrides the YAML file).
* The script can now compile modules independently using the `-l`/`--as-module` flag.
* The script can now clear the output folder using the `-b`/`--clear-output` flag (replaces the `clear_folder.py` script from the previous release).
* The script can now test compilation using all possible combinations of compilers and C++ standards available in the system using the `-y`/`--try-all` flag (replaces the `test_all.py` script from the previous release).
* The script now automatically detects the Visual Studio installation path on Windows.
* The script now implements a more robust mechanism for finding the `std` module.
* The script now prints colored output for better readability. This can be disabled by setting the `NO_COLOR` environment variable.
* The script no longer disables optimizations when compiling with GCC and modules (since that bug is fixed in recent versions of GCC).
* Added a VS Code task to compile the test program (or the active file) with all available compilers and all relevant C++ standards, but without running it, to quickly check for compiler compatibility issues.
### v5.0.0 (2024-12-19)
* A major new release with many new features, improvements, bug fixes, and performance optimizations! Please note that code written using previous releases may need to be modified to work with the new release. The changes needed to migrate to the new API are explicitly indicated below for your convenience.

* **Development:**
* A Python script `compile_cpp.py` has been added to the repository, in the `scripts` folder. It can be used to compile any C++ source file with different compilers on different platforms. The compilation parameters can be configured using command line arguments and/or via an optional YAML configuration file `compile_cpp.yaml` which specifies defined macros, extra compiler flags (per compiler), include folders, modules, and the output folder.
* I wrote this script to make it easier for me to test the library with different combinations of compilers, standards, and platforms using the built-in Visual Studio Code tasks. I also included three `.vscode` folders (one for each OS) in the repository, with appropriate `c_cpp_properties.json`, `launch.json`, and `tasks.json` files that utilize this script, in case you want to use it in your own projects. However, note that this script is not meant to replace CMake or any full-fledged build system, it's just a convenient script for developing single-header libraries like this one or other small projects.
* The `compile_cpp.py` script also transparently handles C++20 modules and importing the C++ Standard Library as a module in C++23. Therefore, users of this library who wish to import it as a C+20 module may find this script particularly useful.

* Another Python script `test_all.py` in the `scripts` folder replaces the old PowerShell test script. Tests are now performed in C++17, C++20, and C++23 modes, using all compilers available in the system (Clang, GCC, and/or MSVC). Since there are so many tests, the test script now no longer performs the benchmarks, as that would take too long.
* A final Python script `clear_folder.py` in the `scripts` folder is used to clean up output and temporary folders, and integrates with VS Code tasks.
