# Grit 0.8.1

Grit 0.8.1 is out now. I've made three somewhat small changes here. First, there was some trouble with shared palettes/tiles if there was no -O or -S option. “Trouble”, as in segmentation fault. This should now be fixed.

I've also reformatted the include guards from __FOO__ to GRIT_FOO_H. GCC uses that format for internal #defines and it is very territorial about such matters. So, say, when you have elf.png, GCC gets cranky because that would hide its own __ELF__, and guess who wins out there? Again, thanks for pointing these things out, Quirky.

The last item is the addition of column-major tiling. This can be useful for horizontal scrolling games, since the data or the columns are all adjacent instead of a whole scanline apart. A second benefit of this mode is that rendering to tiles is made considerably easier (and a little bit faster too).

In case you hadn't noticed yet, I've also put the manual on-line. This shows the basic options for grit and wingrit, and now there's a description of how to use it in makefiles as well. This includes how the building the grit-demo project works. This one's quite interesting, so please check it out.
