Throughout this year (if you are referring to the present calendar year) Throughout last year Over the last few years Bottom line – be careful of how you use “during” to refer to time periods

We updated X to overcome Y. => We updated X to address Y.
If you feel you need to be explicit, then be explicit. Write two sentences.
