Planet generation modified?

[Snowpig]

i usually use seed 8887 to generate a planet with a very cold spot to play with the icesheet mod. after installing A9 i noticed, that the lowest (january-) temperature on coldest spot on the map went up from -101.5°C (A8) to around -80.6°C. In addition the altitude of the map went down from ~5500m to ~4800m.

Was the planet-generation algorithm changed deliberately?

I don't know about those changes, but a change I noticed with A9 is that the first world I generated seemed to span both the northern and southern hemispheres, with polar caps at both the top and the bottom of the map and the tropics in the center (including seasonal differences in the southern hemisphere that at first glance seemed to make sense).  Prior to A9 every generated world seemed to be northern hemisphere only, with the equator at the bottom of the map.

However, I just tried generating another world in A9, and this time it was once again only the northern hemisphere.  So I'm no longer sure how that happened.  Maybe I just dreamed it?
