We previously set the deprecation warning to an "always" filter, however this has unintended consequences - it voids user's own filters, so it makes the warning impossible to turn off. If running code in parallel, this can lead to it being practically impossible to stop the warning being printed multiple times, making it very annoying. I think we shouldn't be over-riding users own warnings settings - so this removes the "always" filter.
