Riverheim changelog

v1.0.0

The release version, a major overhaul of all aspects of Riverheim.

New feature: budgeted generation of biomes, lakes and mountains. Worlds are more consistent and even outliers should be playable.
New feature: channels can cut through larger landmasses to connect distant bodies of water.
New feature: sub-biomes present themselves to Valheim as existing biomes, but have distinct terrain.
Marsh is a rare sub-biome of meadows that is mostly submerged in water. Patches of marsh can be found adjacent to water sources.
Mistglade is a rare sub-biome of mistlands with mellow terrain and no mist. Patches of mistglade can be found deep within their parent biome.
Mountains are rarer and grander in scale.
More variety in the river network.
Various local terrain features at key locations like river sources.
Improved cliffs and biome-specific terrain variations.
Ashlands no longer borrows terrain generation from the base game.
Independent generation of different regions of the world to prepare for Deep North.
New metadata format for save files. Some of the generation parameters are now stored in the save file enabling safe updates.
Consistent generation across different 64-bit platforms.
Improved performance.
Innumerable improvements to the foundation code to ensure stability and reproducibility.

Merged mod assemblies into one.
Rivers are now approximated by segments rather than points, eradicating occasional unnatural looks at low widths.
River profile has changed to be less extreme at large heights, resulting in fewer blending artifacts.
Different rivers are now blended separately which should eliminate sharp rock formations between them.
River rendering has been optimized to be marginally faster.
The above changes produce difference in heightmap compared to 0.11, but it is not drastic and is only contained in close proximity to rivers.

Fixed a bug that occasionally prevented joining other servers with a client with other mods installed that presented in an "Incompatible version" error when in fact versions have been compatible.
Starting from 0.11, version checks are relaxed to major.minor. Patch versions are going to be compatible between each other.

Fixed a bug introduced in 0.10.0 that made all terrain rocky and impossible to cultivate.

Fixed fish spawning, oceans are now slightly less deep so fish can properly rise to the surface.
Fixed leviathans barely spawning.
Slightly lowered overall height of Swamp, improving spawn of locations like the Bog Witch.
Reduced the amount of unnavigable shallows at the coast of Plains.
Added support for the None biome to support custom biomes in other mods. It will just use base heights with rivers/splats.
Added world metrics logging after world generation.
Patched server-side startup so that the server will terminate with an exception instead of silently creating a new world upon attempt to load a world that's not compatible.
