Map format serialization version
--------------------------------
For map data (blocks, nodes, sectors).
NOTE: The goal is to increment this so that saved maps will be
loadable by any version. Other compatibility is not
maintained.
Serialization format versions (for raw map data (blocks, nodes, sectors)):
== Unsupported ==
0: original networked test with 1-byte nodes
1: update with 2-byte nodes
== Supported ==
2: lighting is transmitted in param
3: optional fetching of far blocks
4: block compression
5: sector objects NOTE: block compression was left accidentally out
6: failed attempt at switching block compression on again
7: block compression switched on again
8: (dev) server-initiated block transfers and all kinds of stuff
9: (dev) block objects
10: (dev) water pressure
11: (dev) zlib'd blocks, block flags
12: (dev) UnlimitedHeightmap now uses interpolated areas
13: (dev) Mapgen v2
14: (dev) NodeMetadata
15: (dev) StaticObjects
16: (dev) larger maximum size of node metadata, and compression
8: server-initiated block transfers and all kinds of stuff
9: block objects
10: water pressure
11: zlib'd blocks, block flags
12: UnlimitedHeightmap now uses interpolated areas
13: Mapgen v2
14: NodeMetadata
15: StaticObjects
16: larger maximum size of node metadata, and compression
17: MapBlocks contain timestamp
