Even if the release wasn't deliberate, their reaction to it certainly wasn't accidental. They tried to shut down travel to the rest of China from Wuhan, but still allowed people to travel to the rest of the world. The only reasonable explanation that I can come up with is that they were deliberately trying to spread it to the rest of the world.
The timing is also too much for me to consider it coincidental. I just don't think it matters much if it was released deliberately or not. The end result is the same either way.
