Odd Even Count Sudoku 2017 - 1

And today we have the final request of Rakesh being fulfilled. We have an Odd Even Count Sudoku. I had thought that I will be creating this after coming back from the Times Sudoku Championship finals, but since I managed to create it in advance, here I am posting it. There will be a lull on Sunday as I will be out of town for the championship. See you all on Monday.

Rules of classic Sudoku apply. Additionally, An even number placed in a cell with a circle indicates the number of even numbers placed in the surrounding 8 cells. An odd number placed in a cell with a circle indicates the number of odd numbers placed in the surrounding cells. Numbers placed in cells without a circle may have either of these properties.
