These are unrelated to the Player API and player object.
All other GUI/HUD code and textures are in default.
All other engine hardcoded sounds are in default.
The player_api mod is highly likely to be used unchanged in new games,
so logical grouping of content will help the creation of new games.

Update side texture to match the new top texture.
3/4 side coverage instead of 1/2,

Alter 'large cactus' schematic to place another force-placed cactus node,
to replace the cactus seedling on growth.
Make schematic 5x7x5 to solve rotation, placement and protection check
issues.
Add a y-slice probability for height variation.

Growth time is tuned to not make this a faster way to obtain cactus nodes
compared to normal cactus farming.
Seedling texture by Extex101.

Use sapling/seedling description in protection intersection message in
'sapling_on_place' function.

sfinv:
Move license information to create the missing license.txt file.
Make README consistent with other Minetest Game mods.

player_api:
Add missing texture and sound credits to README.
Update and add extra license information.

default:
Remove credit for 'player_damage.ogg' sound.

Replaces 'bush' in snowy grassland.

Move chests code out of nodes.lua and into a new file.
Credit torch code, and chest and torch models in README.txt.
Remove 'torches' mod text from torch.lua.
Minor cleanups in README.txt.

Minor clean up of README.txt, including deletion of credits for removed
torch textures.

Move previous tundra to highland and remove the snowblocks that are
unsuitable for a fairly dry biome, use snow slabs instead.

Height 20 to 32 nodes.
Dependent on chunksize >= 5.
Base limited to maximum altitude y = 32.
Craft sapling from 9 jungle saplings.

Use noise with 1 octave and flag 'absvalue' to create sand paths
in dunes.

Remove flowers from coniferous forest.
Add 'dirt with coniferous litter' to farming mod overrides.

Add and use 'default.node_sound_snow_defaults()' function.

Original texture by tobyplowy, colourised by paramat.

This keeps the filenames the same, but adds a new "inside" double texture
for the open chest.
Use regular drawtype for closed chest and delete the "cube.obj" model.
X-flip the right-side texture for the closed chest.

Prevents generating ugly looking dummy images for mods that weren't updated yet.

Adds a mesh model that appears when a chest is opened. The chest
stays visibly open as long as the player keeps it open. When the
player closes the formspec, the chest returns back to the closed
shape. While opening and closing, a sound plays.

A second person inspecting the chest will trigger a second sound
open. However, only after the last player closes the chest, does the
chest actually visually close and is the sound close played. This
keeps mesh updates to a minimum.

While it's possible that a server shutting down may cause chests
to remain open, this does not affect the chests' working matter,
and opening or closing them should fix them.

Old chests are converted to the new style by LBM. I previously
had them converted on open but this was unreliable, and LBMs
don't have that problem.

Open chests cannot be dug up. This prevents people from keeping
a chest open and digging it out as well, since closing a chest
would place a chest back (swap) at the spot. We could protect
against this, but it still messes up the client and causes a lot
of "missing node inventory" error messages otherwise. It's
unlikely but possible that a player lagging out causes a chest
to stay "open" and thus unremovable by digging, but there are
other ways of dealing with that - a server restart fixes that
issue.

If the lid of the chest is obstructed, the sounds continue to play,
but the lid isn't opened. Obstructed means that a node is present
above the chest lid, however, we ignore several node types like signs,
torches (not 3d) and wallmounted nodeboxes (typically signs) since
they don't pose any major obstruction in almost any case, and are
typically found above chests. Additionally, the selection box of the
opened chest does not include the lid, and so one can still interact
with e.g. a sign behind an open lid.

Due to the fact that chests now have 7+ textures, we can no longer
use materials (limit: 6) to texture the chest, and so there is now
a single UV mapped image that applies both to open and closed chests.
While this does mean texture pack makers need to create it, this
is extremely simple and consists of a simple cut'n'paste over the
template and should be really easy to do. Only one texture file is
now then used for both open and closed chests.

Previously i had matched ore density to moreores, but this density was
too high and out of balance with MTGame, reduce density to be similar
to copper ore.
The 2 levels of underground ore were overlapping, fix.
Textures are actually by kilbith, update credits.

Also credit kilbith for bronze, copper, gold and steel blocks, credits
had not been updated at the time.

Use Calinou's textures from moreores mod.
Craft bronze from tin and copper instead of steel and copper.
Match ore density to the moreores mod but start ore at a depth of
y = -32 to be part of the depth progression of other ores.

Bush saplings grow in half the time of tree saplings.
Bushes do not need 'from sapling' schematic variants because only the
stem node is force-placed in the mapgen schematic, so only the sapling
is force-replaced.
Bush leaves drop saplings with a rarity that ensures at least 1 sapling
per bush on average.

Add desert and silver sand-related blocks, and stairs.
