 ### Features
 
 * lang: `Program` type introduced for executable accounts ([#705](https://github.com/project-serum/anchor/pull/705)).
 * lang: `Signer` type introduced for signing accounts where data is not used ([#705](https://github.com/project-serum/anchor/pull/705)).
+* lang: `UncheckedAccount` type introduced as a preferred alias for `AccountInfo` ([#745](https://github.com/project-serum/anchor/pull/745)).

 ### Features
 
 * lang: Add new `Account` type to replace `ProgramAccount` and `CpiAccount`, both of which are deprecated ([#686](https://github.com/project-serum/anchor/pull/686)).
+* lang: `Box` can be used with `Account` types to reduce stack usage ([#686](https://github.com/project-serum/anchor/pull/686)).
 * lang: Add `Owner` trait, which is automatically implemented by all `#[account]` structs ([#686](https://github.com/project-serum/anchor/pull/686)).
 * lang: Check that ProgramAccount writable before mut borrow (`anchor-debug` only) ([#681](https://github.com/project-serum/anchor/pull/681)).
