A point release largely addressing build problems related to fmtlib integration, along with dynamic WASAPI device enumeration fixes and resampler improvements.

• Fixed using as a static library when linked into another project that uses fmtlib.
• Fixed building with static VC runtimes.
• Fixed building with Windows headers that default to older targets.
• Fixed building on 32-bit targets that use 32-bit file offsets.
• Fixed handling WASAPI enumerated device changes.
• Fixed a crash with UWP builds when __wargv is null.
• Fixed using AL_FORMAT_BFORMAT3D_I32.
• Improved the bsinc resamplers' cutoff frequencies.
• Slightly reduced the aliasing noise in the cubic spline resampler.
• Added new bsinc48 and fast_bsinc48 resampler options.
• Added support for 16KB page sizes on Android.
• Added support for using NFC filters with UHJ output.

Full Changelog: 1.24.2...1.24.3

A point release to address some build compatibility problems, missing features, and bug fixes.

• Implemented the AL_SOFT_bformat_hoa extension.
• Implemented default device change events for the PulseAudio backend.
• Implemented an option for WASAPI exclusive mode playback.
• Fixed reverb being too quiet for sounds from different directions.
• Fixed compiling with certain versions of Clang.
• Fixed compiling for some older macOS versions.
• Fixed building alffplay on systems without pkg-config.
• Improved output format detection for CoreAudio.
• Changed the default resampler back to Cubic Spline.
• Added an SDL3 playback backend. Disabled by default to avoid a runtime dependency and for compatibility; a single process can't safely use SDL2 and SDL3 together on some OSs, so enable with care.
• Converted examples from SDL2 to SDL3.
• Integrated fmtlib into the main library and router for logging and string formatting.

Full Changelog: 1.24.1...1.24.2

A point release to address a runtime error and some build problems.

• Fixed compilation on PowerPC.
• Fixed compilation on some targets that lack lock-free 64-bit atomics.
• Fixed a crash when parsing certain option values.
• Fixed applying noexcept in the public headers with MSVC.
• Fixed building for UWP with vcpkg.
• Improved compatibility when compiling as C++20 or later.
• Integrated fmtlib for some examples and utilities.

Full Changelog: 1.24.0...1.24.1

A long overdue release. This release's highlights include:

• Updated library codebase to C++17.
• Implemented the ALC_SOFT_system_events extension.
• Implemented the AL_EXT_debug extension.
• Implemented the AL_EXT_direct_context extension.
• Implemented speaker configuration and headphones detection on CoreAudio.
• Fixed a potential crash with some extension functions on 32-bit Windows.
• Fixed a crash that can occur when stopping playback with the Oboe backend.
• Fixed calculating the reverb room rolloff.
• Fixed EAX occlusion, obstruction, and exclusion low-pass filter strength.
• Fixed EAX distance factor calculations.
• Fixed querying AL_EFFECTSLOT_EFFECT on auxiliary effect slots.
• Fixed compilation on some macOS systems that lack libdispatch.
• Fixed compilation as a subproject with MinGW.
• Changed the context error state to be thread-local. This is technically out of spec, but necessary to avoid race conditions with multi-threaded use.
• Split the cubic resampler into 4-point spline and gaussian variants. The latter prioritizing the suppression of aliasing distortion and harmonics, the former not reducing high frequencies as much.
• Improved timing precision of starting delayed sources.
• Improved ring modulator quality.
• Improved performance of convolution reverb.
• Improved WASAPI device enumeration performance.
• Added UWP support.
• Added 'noexcept' to functions and function types when compiled as C++. As a C API, OpenAL can't be expected to throw C++ exceptions, nor can it handle them if they leave a callback.
• Added an experimental config option for using WASAPI spatial audio output.
• Added enumeration support to the PortAudio backend.
• Added compatibility options to override the AL_VENDOR, AL_VERSION, and AL_RENDERER strings.
• Added an example to play LAF files.
• Disabled real-time mixing by default for PipeWire playback.
• Disabled the SndIO backend by default on non-BSD targets.
