that recent anouncement was for direct entry to quatar or departure from quatar. It clearly states that it is not applicable for the travellers using quatar as transist only. It may change later, but for now you are fine as you are expecting to use doha as transit only. I was in doha 10 days ago, and there was no temperature check for us (transist) , but it was there in TIA. My return flight was supposed to be on 31st march, I just received (literally 30 mins ago) about my schedule changes. They cancelled 8:45 pm flight and pushed to 2 am flight . This is likely because travellers to quatar as a destination are cancelled , so they trying to fit everyone in single flight.
