mlua/CHANGELOG.md

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.
• 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.
