Ethereal clears every biome when it starts to get rid of the default mapgen, which breaks the nether and can cause crashes.
Adding Ethereal as an optional dependency ensures the nether is loaded after Ethereal has already cleared the biomes.
* clears netherrack from dungeon stairways
* Adds pillars or mezzanine floors to large rooms
* slightly more careful with window placement
* glowstone sometimes added behind in windows
Add more appropriate/atmosphere distance fog to the nether, via climate_api mod to avoid conflicting with other mods.
Any game or server with climate_api mod installed will be expecting climate_api to take control of sky values.
The error below was reported, so handle the existence of a mod called "bucket" which doesn't have any liquids field:
Runtime error from mod 'nether' in callback on_mods_loaded(): /mods/environment/nether/nodes.lua:378: attempt to index field 'liquids' (a nil value)
stack traceback:

Adds a magma oceans region to the nether outside the existing nether caverns, which can be reached via tunnels.
Other misc changes:
* chatcomment nether_whereami, a debug aid for knowing which perlin-noise region you are in
* Nether ores no longer obtainable on the ceiling
* Move crafts into crafts.lua
* Add steam to lava cooling, and play bubbling lava upon death by lava
* Add cracked netherbrick
a decorative node which can only be obtained from dungeons or structures
I encourage someone to improve or replace the cracked netherbrick texture. For copyright purposes it's currently a derivative work (by me, 2020) from nether_brick.png, which is licensed under CC BY-SA 3.0 by PilzAdam, so it can fall under the "All other media" PilzAdam's credit in readme.md rather than need its own entry.
* textures for new tool items
* axe, shovel, pick, sword based on nether
* run also tools.lua
* Textture for Compressed Netherbrick
* new node "Compressed Netherbrick"
* define how to craft "Compressed Netherbrick"
* change recipe for NetherLump and remove old node
* Delete nether_nether_compressed.png
The round ones look nice and cartoony, but not the right art direction for Minetest Nether.
Making use of the existing default_item_smoke.png is also a close contender for smoke puffs, but it's not translucent and I think the roundness of it reduces how much the puffs form into plumes.
Portals will now fail to ignite instead of defaulting to a fallback depth of (starty - 256) when no unprotected target can be found.
The search depth is also increased from (starty - 256) to (starty - 646)
This is to properly handle large protected areas that are sometimes set up at spawn - see issue #26
* respect protected areas when spawning remote portals
* Use portal_shape to determine area to check for natural/protected
* Log warning on deprecated function call
