[IMP] Average price correction + Lot should be changeable in bar code interface
[IMP] Gives warning when the product needs tracking in bar code interface + pack ops with packs don't need lot for related moves
[IMP] is_product_variant not needed in most views + no delete in stock valuation history
[IMP] No attrs for taxes and income/expense accounts
[IMP] Condition tag would not be upgraded when migrating
[IMP] Type manufacturing orders, remove double accounting entries, child_of, push rule global has no route
[FIX] Change two-one step wh, multi-comp wh, quantity field float, show product_uom_qty instead of product_qty in mrp production for moves
[FIX] Don't change to product_uom_qty if not move
[IMP] Not necessary as operations are computed, but more logical to do action_pack as dropdown(process)
