-Minetest World Format 22...27
+Minetest World Format 22...29
=============================
This applies to a world format carrying the block serialization version
- 0.4.0 (23)
- 24 was never released as stable and existed for ~2 days
- 27 was added in 0.4.15-dev
+- 29 was added in 5.5.0-dev
The block serialization version does not fully specify every aspect of this
format; if compliance with this format is to be checked, it needs to be
backend = sqlite3 - which DB backend to use for blocks (sqlite3, dummy, leveldb, redis, postgresql)
player_backend = sqlite3 - which DB backend to use for player data
readonly_backend = sqlite3 - optionally readonly seed DB (DB file _must_ be located in "readonly" subfolder)
+ auth_backend = files - which DB backend to use for authentication data
server_announce = false - whether the server is publicly announced or not
load_mod_<mod> = false - whether <mod> is to be loaded in this world
- auth_backend = files - which DB backend to use for authentication data
+
+For load_mod_<mod>, the possible values are:
+
+* `false` - Do not load the mod.
+* `true` - Load the mod from wherever it is found (may cause conflicts if the same mod appears also in some other place).
+* `mods/modpack/moddir` - Relative path to the mod
+ * Must be one of the following:
+ * `mods/`: mods in the user path's mods folder (ex `/home/user/.minetest/mods`)
+ * `share/`: mods in the share's mods folder (ex: `/usr/share/minetest/mods`)
+ * `/path/to/env`: you can use absolute paths to mods inside folders specified with the `MINETEST_MOD_PATH` env variable.
+ * Other locations and absolute paths are not supported
+ * Note that `moddir` is the directory name, not the mod name specified in mod.conf.

Player File Format
===================
NOTE: Byte order is MSB first (big-endian).
NOTE: Zlib data is in such a format that Python's zlib at least can
directly decompress.
+NOTE: Since version 29 zstd is used instead of zlib. In addition the entire
+ block is first serialized and then compressed (except the version byte).

then Minetest will correct lighting in the day light bank when
the block at (1, 0, 0) is also loaded.

+ - Timestamp when last saved, as seconds from starting the game.
+ - 0xffffffff = invalid/unknown timestamp, nothing should be done with the time
+ difference when loaded
