Lua, a lightweight, high-level scripting language designed for embedding into other applications, has just rolled out version 5.5.
One of the key additions is explicit global variable declarations, enabling developers to define globals more clearly and avoid common errors associated with implicit globals. In addition, variables in for-loops are now read-only, reducing unintended side effects in loop constructs.
Memory usage for arrays has been significantly optimized in Lua 5.5. According to devs, implementing more compact arrays reduces the memory footprint of large tables by approximately 60 percent, improving performance for data-intensive applications
