# What's changed? * Compiler now targets bytecode version 5 by default, this includes support for vector type literals and sub/div opcodes with a constant on lhs ### New Type Solver * Normalizer type inhabitance check has been optimized * Added ability to reduce cyclic `and`/`or` type families ### Native Code Generation * `CodeGen::compile` now returns more specific causes of a code generation failure * Fixed linking issues on platforms that don't support unwind frame data registration --- ### Internal Contributors Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com> Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: David Cope <dcope@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com>
