- Added support for `Array.from` and `Array.of`

- Added support for `beforeEmit` hook to plugins that runs after tstl is totally done, but before emitting the result.

- For more info about plugin hooks, see: https://typescripttolua.github.io/docs/api/plugins

- Added support for import expressions (`import("./module").then(m => m.foo());`)

- Added tsconfig setting `lua51AllowTryCatchInAsyncAwait` to disable restrictions on try/catch in combination with async/await in 5.1 (default: false)

- Added tsconfig setting `noImplicitGlobalVariables` to disable tstl making variables global in non-module files.

- Various lualib optimizations

- JSDoc comments from input TS are now also part of output Lua as LDoc comments.

- Can be disabled with `removeComments` tsconfig setting.

- Rewrote how try/catch works in async functions, fixing many bugs.

- Fixed a bug where methods with non-null expressions (i.e. `obj.method!()`) would not pass the correct self parameter, causing runtime errors.

- Fixed a bug where symlinked node_modules (for example when using `npm link`) were not recognized as external dependencies by module resolution.

- Fixed a bug with sourcemap traceback leading to invalid lua

- Improved sourcemap traceback interaction with `loadstring`
