It was meant to have been released, but the latest I heard it was pushed back to around the 15th..
Oh and the cool demo player has been shunted to 1.6, also in 1.6 will be Narbys map de_comrade
This release is meant to have de_piranessi ( steam beta test map ) and some bug fixes ( nothing noteworthy ). And they have added a few more anticheat bits too..
