We just released a patch for 0.1.9

It's a relatively minor update, focused on removing known bugs and bringing 0.1.9 up to full feature parity with 0.1

• It's now possible to save world defines (which from now on is the preferred way of saving worlds between versions)
• Two new map modes (Volcanic map mode and Ice age map mode)
• Koppen climate is now displayed in the tile inspector
• Background galaxy is back
• Temperature map modes should work again
• Fixed some minor UI bugs
