+============
+- Added :func:`~arch.univariate.base.ARCHModelResult.std_resid` (:issue:`326`).
 - Error if inputs are not ndarrays, DataFrames or Series (:issue:`315`).
 - Added a check that the covariance is non-zero when using "studentized" confidence intervals.
   If the function bootstrapped produces statistics with 0 variance, it is not possible to
