 - `correlator` now throws an `ArgumentError` when the sites are not ordered as `i < j`.
   Previously such a call only logged an `@error` and then continued into a contraction that is
   not the requested correlator. ([#489](https://github.com/QuantumKitHub/MPSKit.jl/pull/489))
+- TimerOutputs 1.x is now required. The timing tables printed at `verbosity > 3` use the new

 ### Deprecated
 
 ### Removed
 
+- Support for TimerOutputs 0.5.
+
 ### Fixed
 
 - `isfinite(::WindowMPOHamiltonian)` was undefined. ([#489](https://github.com/QuantumKitHub/MPSKit.jl/pull/489))
