## v0.6.0-beta.3
- Errors are always `Send + Sync` to be compatible with anyhow crate
- Implement `UserData` for `Rc<RefCell>`/`Arc<Mutex>`/`Arc<RwLock>`
- Added `__ipairs` metamethod for Lua 5.2
- Added `String::to_string_lossy`
- Various bugfixes and improvements
## v0.6.0-beta.2
- [**Breaking**] Removed `AnyUserData::has_metamethod()`
- Added `Thread::reset()` for luajit/lua54 to recycle threads.
It's possible to attach a new function to a thread (coroutine).
- Added `chunk!` macro support to load chunks of Lua code using the Rust tokenizer and optinally capturing Rust variables.
- Improved error reporting (`Error`'s `__tostring` method formats full stacktraces). This is useful in the module mode.
## v0.6.0-beta.1
- New `UserDataFields` API
- Allow to define arbitrary MetaMethods
- `MetaMethods::name()` is public
- Do not trigger longjmp in Rust to prevent unwinding across FFI boundaries. See https://github.com/rust-lang/rust/issues/83541
- Added `SerializeOptions` to to change default Lua serializer behaviour (eg. nil/null/array serialization)
- [**Breaking**] Removed `Result` from `LuaSerdeExt::null()` and `LuaSerdeExt::array_metatable()` (never fails)
- [**Breaking**] Removed `Result` from `Function::dump()` (never fails)
- `ToLua`/`FromLua` implementation for `Box<str>` and `Box<[T]>`
- [**Breaking**] Added `LuaOptions` to customize Lua/Rust behaviour (currently panic handling)
- Various bugfixes and performance improvements
## v0.5.4
- Build script improvements
- Improvements in panic handling (resume panic on value popping)
- Fixed bug serializing 3rd party userdata (causes segfault)
- Make error::Error non exhaustive
## v0.5.3
- Fixed bug when returning nil-prefixed multi values from async function (+ test)
- Performance optimisation for async callbacks (polling)
## v0.5.2
- Some performance optimisations (callbacks)
- `ToLua` implementation for `Cow<str>` and `Cow<CStr>`
- Fixed bug with `Scope` destruction of partially polled futures
## v0.5.1
- Support cross compilation that should work well for vendored builds (including LuaJIT with some restrictions)
- Fix numeric types conversion for 32bit Lua
- Update tokio to 1.0 for async examples
## v0.5.0
- Serde support under `serialize` feature flag.
- Re-export `mlua_derive`.
- impl `ToLua` and `FromLua` for `HashSet` and `BTreeSet`
## v0.4.2
- Added `Function::dump()` to dump lua function to a binary chunk
- Added `ChunkMode` enum to mark chunks as text or binary
- Updated `set_memory_limit` doc
## v0.4.0
- Lua 5.4 support with `MetaMethod::Close`.
- `lua53` feature is disabled by default. Now preferred Lua version have to be chosen explicitly.
- Provide safety guaraness for Lua state, which means that potenially unsafe operations, like loading C modules (using `require` or `package.loadlib`) are disabled. Equalient for the previous `Lua::new()` function is `Lua::unsafe_new()`.
- New `send` feature to require `Send`.
- New `module` feature, that disables linking to Lua Core Libraries. Required for modules.
- Don't allow `'callback` outlive `'lua` in `Lua::create_function()` to fix [the unsoundness](tests/compile/static_callback_args.rs).
- Added `Lua::into_static()` to make `'static` Lua state. This is useful to spawn async Lua threads that requires `'static`.
- New function `Lua::set_memory_limit()` (similar to `rlua`) to enable memory restrictions in Lua VM (requires Lua >= 5.2).
- `Scope`, temporary removed in v0.3, is back with async support.
- Removed deprecated `Table::call()` function.
- Added hooks support (backported from rlua 0.17).
- New `AnyUserData::has_metamethod()` function.
- LuaJIT 2.0.5 (the latest stable) support.
- Various bug fixes and improvements.
