β This issue applies solely to users that have been using the "Optimized HIFO" Beta method with "Wallet-based cost tracking". If you are not using wallet-based tracking, then this will not affect you.
Prior to this update, Optimized HIFO only supported the universal cost-tracking method. Using Optimized HIFO with wallet-based cost tracking would result in tax lots being selected in an undefined order when transferred between wallets.
We have now added support for wallet-based cost tracking, so that tax lots are selected correctly when transferred between wallets.
