v0.0.19

New Features

• LuaJIT's built-in CPU profiler can be enabled with the new profile command, or loaded as profiler
• A syslog library has been added to support formatted log messages that tie into the event system
• The eval command provides a REPL for interactive code evaluation if no arguments were passed
• Added a debug command that allows running apps in debug mode, where event logging is always enabled
• Two extensions have been added to the table library: table.reverse and table.invert
• The etrace library received support for event listeners via publish,subscribe, and notify
• Optimized bit operations for C++ numerics are now available: ceil, floor, ispow2, and width

Improvements

• Error details are now displayed in reverse order by bdd reports to reduce the need for scrolling
• Encoding options should correctly be passed to json.stringify (and not just json.encode)
• Apps can now use json.encode with cdata and other values that provide a __tostring metamethod

Breaking Changes

• Replaced the global EVO_VERSION variable with runtime.version(), which supports multiple returns
• The WebGPU FFI bindings are now preloaded as wgpu instead of webgpu, providing the same API
• Moved stbi.replace_pixel_color_rgba from Lua to C++ (apps must now access it via stbi.bindings)
