mlua/CHANGELOG.md

[0.11.0]

• rlua::Error now implements failure::Fail and not std::error::Error, and external errors now require failure::Fail. This is the only API incompatible change for 0.11, and my hope is that it is relatively minor. There are no additional bounds on external errors, since there is a blanket impl for T: std::error::Error + Send + Sync of failure::Fail, but rlua::Error no longer implements std::error::Error and there is an additional dependency, and that is more likely to cause breakage.
• protect a call to luaL_ref when creating new userdata types.
• Some documentation improvements for Error, Lua::create_function, and MetaMethod, and a rustdoc warning fix (thanks @jonas-schievink!)
• Expose the RegistryKey type in the API properly, which makes the API around it vastly easier to use! Also fixes a safety hole around using the RegistryKey API with the wrong Lua instance.
• Add an API for "user values", which are arbitrary Lua values that can be attached to userdata.

[0.10.2]

• Registry API for storing values inside the Lua instance, either by string or by automatically generated keys.
• Important memory safety fix for luaL_ref.

[0.10.1]

• Documentation spelling fix

[0.10.0]

• Handle all 'm' functions in the Lua C API correctly, remove LUA_ERRGCMM hacks.
• Lots and lots of internal changes to support handling all 'm' errors
• Change the API in a lot of places due to functions that can trigger the gc now potentially causing Error::GarbageCollectorError errors.

[0.9.7]

• Add unsafe function to load the debug Lua module (thanks @Timidger!)
• Fix setmetatable wrapper with nil metatable (thanks again to @Timidger!)

[0.9.6]

• Fix an annoying bug that made external errors appear to have no further cause errors in the cause chain.

[0.9.5]

• Fix incorrect xpcall behavior
• Change FromLua / ToLua impls for HashMap to be generic over the hasher. This may be technically a backwards incompatible change, but this would be really unusual though, and I don't think it deserves an API bump.

[0.9.4]

• Fix quadratic behavior in Function::bind
• lua_checkstack fixes, particularly fixing a crash bug due to luaL_ref using a single extra stack space.

[0.9.3]

• Soundness fix for recursive function calls, now causes a panic. This is temporary while I work on a more major update that prevents panics / aborts from scripts.

[0.9.2]

• Bugfix, don't load the "base" library into the "base" global variable @jonas-schievink
• Additional documentation work, a link fix for Variadic docs, new crate documentation @jonas-schievink
• Metatable access on Table
• gcc crate warning fix for 0.3.52 and up
• Bugfix for Table::raw_get, now actually calls raw_get and is sound.

[0.9.1]

• Add travis badge

[0.9.0]

• Huge API change, removed the Lua prefix on all types, changes to callback signature that remove the need for manual wrapping and unwrapping in most cases.
• Tons of soundness bugfixes, very few soundness problems remain.
• Tons of documentation and bugifx work @jonas-schievink

[0.8.0]

• Major API change, out of stack space is no longer an Err, you should not be able to run out of stack space by using this API, except through bugs.
• Simplification of error types

[0.7.0]

• API change to remove dependency on error_chain, major changes to error handling strategy to allow Lua to catch and rethrow rust errors sanely.
