New Release Schedule
Up until now, releases of ares were made when the changes felt 'significant' enough to do so. As of v135, we are moving to a monthly release schedule.

We will aim to publish a new release each month from this point forward, however, there is no strict date allocated for this, so there's still an aspect of 'when suitable'.
