• Lua 5.5 support under the new lua55 feature flag
• Luau updated to 0.705+
• Added AnyUserData::is_proxy

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.5...v0.11.6

Lua 5.5 support external strings and mlua enable this optimisation for impl IntoLua for String/BString (owned versions to move Drop into Lua). Also the Lua::create_external_string function allow moving ownership to Lua for any Into<Vec<u8>> types.

• Luau updated to 0.701
• Added Lua::set_memory_category and Lua::heap_dump functions to profile (Luau) memory
• Added Lua::type_metatable helper to get metatable of a primitive type
• Added Lua::traceback function to generate stack traces at different levels
• Added add_method_once /add_async_method_once UserData methods (experimental)
• Make AnyUserData::type_name public
• impl IntoLuaMulti for &MultiValue

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.4...v0.11.5

• Make Value::to_serializable public
• Added new serde option detect_mixed_tables (to encode mixed array+map tables)
• Added ObjectLike::get_path helper (for tables and userdata) for easy access of nested data
• Added (experimental) __namecall optimization for Luau

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.3...v0.11.4

• Added Lua::yield_with to use as coroutine.yield functional replacement in async functions for any Lua (see doc examples)
• Do not try to yield at non-yielable points in Luau interrupt (#632)
• Added Buffer::cursor method (Luau)
• Added Lua::create_buffer_with_capacity method (Luau)
• Make Lua reference values cheap to clone in Rust (only increments ref count)
• Fix panic on large (>67M entries) table creation

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.2...v0.11.3

• Faster stack push for Variadic<T>
• Fix handling Windows paths with drive letter in Luau require (#623) by @piz-ewing
• Make Luau registered aliases ascii case-insensitive (#620)
• Fix deserializing negative zeros -0.0 (#618)

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.1...v0.11.2

• Fixed bug exhausting Lua auxiliary stack and leaving it without reserve (#615)
• Lua::push_c_function now correctly handles OOM for Lua 5.1 and Luau

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.0...v0.11.1

• Allow linking external Lua libraries in a build script (e.g. pluto) using external mlua-sys feature flag
• Lua::inspect_stack takes a callback with &Debug argument, instead of returning Debug directly
• Added Debug::function method to get function running at a given level
• Debug::curr_line is deprecated in favour of Debug::current_line that returns Option<usize>
• Added Lua::set_globals method to replace global environment
• Table::set_metatable now returns Result<()> (this operation can fail in sandboxed Luau mode)
• impl ToString replaced with Into<StdString> in UserData registration
• Value::as_str and Value::as_string_lossy methods are deprecated (as they are non-idiomatic)
• Bugfixes and improvements

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.0-beta.3...v0.11.0

• Luau in sandboxed mode has reduced options in collectgarbage function (to follow the official doc)
• Function::deep_clone now returns Result<Function> as this operation can fail with OOM
• Luau "Require" resolves included Lua files relative to the current directory (#605)
• Fixed bug when finalizing AsyncThread on drop (call_async methods family)

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.0-beta.2...v0.11.0-beta.3

• Lua 5.4 updated to 5.4.8
• Terminate Rust Future when AsyncThread is dropped (without relying on Lua GC)
• Added loadstring function to Luau
• Make AsChunk trait dyn-friendly
• Luau Require trait synced with Luau 0.674
• Luau Require trait methods now can return Error variant (in NavigateError enum)
• Added __type to Error's userdata metatable (for typeof function)
• parking_log/send_guard is moved to userdata-wrappers feature flag
• New serde feature flag to replace serialize (the old one is still available)

Full Changelog: https://github.com/mlua-rs/mlua/compare/v0.11.0-beta.1...v0.11.0-beta.2

• mlua-sys is back to v0.6.x (Luau 0.663)
• Reverted: Trigger abort when Luau userdata destructors are panic (requires new mlua-sys)
• Reverted: Added large (52bit) integers support for Luau (breaking change)
