world generation got configurable: caves, ores, terrain shape and structures are all options now. de8d277
ChunkHelper can generate a seeded world instead of only flat ones. 5add915
versioned entry modules. mc-protocol/26.2 pins a version, the root import tracks the newest one. only Minecraft Java 26.2 (protocol 776) is built in; the multi-version layout is there, the other versions aren’t. cfd5d98
the protocol version is negotiated per connection. groundwork for serving several built-in versions from one Server; today that’s still just 776. 1fa4001
helpers.forVersion() binds the data-backed helpers (items, blocks, chunks and maps) to a protocol version. d78fd31

named item helpers, plus this website. 19b9a1f
command tree, particle and entity metadata helpers. 01ec43e
new Proxy class that sits between a client and a server and lets you intercept packets. 0d8f604 once handlers are honored on the proxy too. 865b66a
map helpers with RGB to map color conversion. 0b0cb18
servers negotiate compression, and client and proxy were checked against it. 043db3a compression is on by default at the vanilla threshold. 2944c3d
fix: automatic negotiation now finishes before your packet listeners run, so you don’t see half-set-up connections. 79685b5
look up vanilla block state ids by name and properties. 11594c3
packet flag helper with named bit maps. e13e3c3 fix: flag map bits are validated and serverbound ability flags are split out. 4de17ac
