+* **eslint-plugin:** [no-unused-expressions] handle ternary and short-circuit options ([#2194](https://github.com/typescript-eslint/typescript-eslint/issues/2194)) ([ee9f100](https://github.com/typescript-eslint/typescript-eslint/commit/ee9f100a2f9a874c2b361482742686eeaa9bdac7))
+* **typescript-estree:** handle TS4.0 breaking change in TupleType ([#2197](https://github.com/typescript-eslint/typescript-eslint/issues/2197)) ([5d68129](https://github.com/typescript-eslint/typescript-eslint/commit/5d6812914831a386997b453b4db1e3283e26005d))
+
+
+### Features
+
+* **eslint-plugin:** [naming-convention] better error message and docs for prefix/suffix ([#2195](https://github.com/typescript-eslint/typescript-eslint/issues/2195)) ([a2ffe55](https://github.com/typescript-eslint/typescript-eslint/commit/a2ffe5568df0f7224bfe9141d298e538383d5f09))
