vkd3d release schedule

[Henri Verbeet]

Hi all,

As you may have noticed, the time between the vkd3d 1.3 and 1.4
releases was a fair bit shorter than the time between the 1.2 and 1.3
releases. That was deliberate; at the start of the year the plan was
made to aim for about 4 vkd3d releases per year. I think that has
worked out well so far, so we'd like to continue along those lines. In
practical terms, that puts the tentative release dates for vkd3d 1.5
and 1.6 at late September and late December this year.
