The old wording could be used to hire bounty hunters as an escort or delivery - since contracts would not specify "hunting".
i.e.: Old: Can attack any ship in pursuit of a contract. >> I hire Bessie Bishop to protect me or deliver RP item to base.
New: Can attack any ship that is the target of a contract. > This one is not subject to interpretation, you can put only a chase contract (follow / spy / monitor/ etc.) or attack if necessary.
You lose escort and courier contracts for BH with the new wording.
