Minetest World Format used as of 0.4.dev-20120322

Minetest World Format 22...23
=============================
This applies to a world format carrying the block serialization version 22
which is used at least in version 0.4.dev-20120322.
This applies to a world format carrying the block serialization version
22...23, used at least in 0.4.dev-20120322 ... 0.4.dev-20120606.
The block serialization version used is 22. It does not fully specify every
aspect of this format; if compliance with this format is to be checked, it
needs to be done by detecting if the files and data indeed follows it.
