An initial report was released in July 2014. Updates were published in July 2015, July 2016, June 2018, and July 2020. The inventory will be updated every two years thereafter.
WSIPP was scheduled to update the inventory in 2022. Instead of an updated, WSIPP assessed the use of the inventory. In the absence of the regular update, WSIPP published a historical review of the LAP inventory, describing potential changes resulting from 2021 legislation, and offering a discussion of options regarding the future of the inventory.
