Release Candidate Version 2023

• Adds error codes for ImageSegment storage primitive fail
• Adds error codes for primitiveFileClose on Linux, macOS, and Windows
• Adds machine-code primitive for #primitiveHighResClock on 64-bit platforms
• Adds machine-code primitive for #perform:withArguments: (84)
• Adds VM parameter 50 for maxLiteralCountForCompile

• Adds support for multi-byte data to ClipboardExtendedPlugin
• Adds support for various data types to ClipboardExtendedPlugin on Windows
• Adds support for UTF8 Unicode to ClipboardExtendedPlugin on Windows
• Adds flag #upscaleDisplayIfHighDPI to be set via command line or stored in image header; true by default
• Adds support for -eventtrace on Linux and Windows
• Fixes memory leak related to scale-factor lookup on Linux (X11)
• Fixes potential GDI leak in getDpiSystem on Windows
• Fixes failure of Spur image segment loading due to not having enough memory
• Fixes path lookup for "." (i.e., current directory) on Windows
• Fixes JIT issue around frameless block activation

• Fixes bug in BitBlt rgbMul combination
• Fixes structure argument passing for ARMv8 FFI call-outs
• Fixes float conversions for FFI call-outs
• Fixes float arguments for FFI call-outs on RiscV64
• Fixes #become: on compiled methods for Spur flavors
• Fixes jitted #perform: primitive by adding argument-count check
• Fixes MoveCqR on ARMv8 for certain bit patterns (in the JIT)
• Fixes crash on ARMv8 when toggling fail/succeed primitives for mixed mode arithmetic
• Fixes accessor-depth calculation in SocketPlugin and other places
• Fixes type-declaration problem in DeflatePlugin for 64-bit RiscV
• Fixes other issues around SmartSyntaxInterpreterPlugins (e.g., JPEGReadWriter2Plugin, BitBltSimulation, SocketPlugin)
• Updates support for compilation on RiscV64 (including FFI plugin)
• Updates VectorEnginePlugin to 2022-10-28 (89cc00e86...) from Cuis
• Updates BitBltPlugin to be faster for noSource/noHalftone setup
• Updates joystick support on Linux

🚧 Compatibility notes

• Pre-built Linux binaries require GLIBC_2.29, which means Ubuntu 20.04 or later
  • For older systems, please build on your own
  • We will happily help out; just ask on the vm-dev mailing list
• On macOS, a restart of the VM is required after installing SqueakFFI for the first time
  • Otherwise, modules and function addresses cannot be loaded

⚠️ Known issues

• On Ubuntu 22.04 within VirtualBox 7.0, screen contents stop refreshing after some keyboard input until mouse cursor is moved again
• On Ubuntu/Linux, many SqueakSSL tests fail on Squeak 6.0+ ... might be an image-related issue
• On macOS, command-line arguments are not passed to the image (see #668)
  • Fixed via 1b15c7e
• On macOS, file-drop crashes the VM
  • Fixed via cc2dd90
• Crashes on RaspPi4; we are investigating
  • The platform subtype can be 'aarch64', which means that (at least in Squeak) the detection of #isLowerPerformance fails and thus lots of tests are timing out. See TestCase >> #defaultTimeout
