Input

• Fixed stuck/ghost keys under multi-key chords — key/keyCode now translated atomically from GLFW key constant on release, not from stale globals (Bug A)
• Fixed phantom key releases on Windows from GLFW virtual key mismatch (GLFW #2417) — scancode-based press tracking drops phantom releases (Bug B)
• Added isKeyDown(int keyCode) API for querying held-key state
• Renamed internal keysDown[256] to _keysDown to avoid collision with user variables

Windows

• Fixed Sketch exited with code -1073741515 (DLL not found) — DLLs now copied from bundled libs/windows-x64/ to sketch folder at launch
• Fixed undefined reference to nanosleep64 with GCC 14.2 — replaced usleep with std::this_thread::sleep_for
• Added libssp-0.dll to runtime DLL copy list
• Removed all MSYS2 references from Windows DLL check
• Fixed extraction progress bar using ZipInputStream with real percentage
• Fixed NoClassDefFoundError for com.sun.management on non-HotSpot JVMs

macOS

• Fixed std::string not in namespace std errors on Apple clang — added #include <string> to Processing_api.h
• Fixed RAND_MAX implicit int-to-float conversion warnings
• Fixed char >= 128 tautological comparison warning
• Fixed sprintf deprecated warning in stb headers
• Fixed ::std:: namespace ambiguity in Processing.cpp on Apple clang
• Bundled universal dylibs (arm64 + x64) in libs/macos/ — no Homebrew required on Apple Silicon or Intel
• checkMacLibs checks bundled dylibs first before falling back to Homebrew

Performance

• Cache no longer invalidated by timestamp — precompiled .o and .gch used if present
• macOS ships precompiled Processing.o and Processing.h.gch for both arm64 and x64
• Low memory threshold raised to 3GB before skipping PCH

Linter

• Fixed double -std flag in PCH generation
• Fixed linter using system g++ instead of portable WinLibs on Windows
• PCH validity now checked by existence only

CI

• macOS dylibs built as universal binaries from source using lipo
• macOS build-cache produces Processing.o and Processing.h.gch for both arm64 and x64
• Integration tests on all 3 platforms
• Upgraded to actions/setup-java@v5
