1.5.0

A Visual Studio Code extension is now available. It provides formatting, live diagnostics, and syntax highlighting for VSCode-based text editors, including VSCodium and Cursor. You can retrieve it from the Open VSX Registry. Those that use other LSP-capable text editors like Vim can take a look at the language server for manual usage.

• Added string interpolation.
• Added lus format command.
• Added runtime attributes for altering local assignments.
• Added error-processing handlers to catch expressions.
• Added initial language server foundation and VSCode extension.
• Enum ordering comparison across different enum roots now raises a runtime error.
• Brought debug.parse to parity with the internal parser.
• Fixed debug.parse serializing linked lists as single nodes instead of arrays.
• Fixed buffer overflow in worker message serialization when arena allocation fails.
• Fixed missing recursion depth limit in worker message deserialization.
• Fixed integer overflow in deser_read bounds check that could allow out-of-bounds reads with large size_t values.
• Fixed negative or huge table counts in worker deserialization being passed to lua_createtable unchecked.
• Fixed missing luaL_checkstack in worker deserialization that could exhaust the Lus stack on deeply nested tables.
• Fixed uninitialized constant slots in enum parsing that could cause a GC crash when luaM_growvector expanded the constants array.
• Fixed race condition in worker receive context signaling that could cause a use-after-free when the receiver destroys a stack-allocated context while a worker thread is still accessing it.
• Fixed missing bounds checking in bundle index parser.
• adjustlocalvars now validates the register limit before assignment.
