Jacques Lucke and Omar Ahmad have presented a first version of AN for Blender 2.8 for testing.
These are only test builds. I do not recommend to use them in any real production.
There will be no support for random crashes that might or might not be caused by Animation Nodes.
Only bugs that are obviously in Animation Nodes will be handled. (Usually those bugs should not crash Blender but produce some longer error message in the console.)
If your scene is crashing, try to get rid of everything AN related in the scene and check if it is still crashing. If the crash persists when Animation Nodes is not enabled, make a bug report in the Blender bug tracker.
There will be no builds for 32 bit systems.
The macOS build was never tested yet. Please let me know if it works via Twitter or BlenderArtists.
