## 18 September 2026

- world generation got configurable: caves, ores, terrain shape and structures are all options now. [de8d277](https://github.com/GDLev/mc-protocol/commit/de8d277)
- `ChunkHelper` can generate a seeded world instead of only flat ones. [5add915](https://github.com/GDLev/mc-protocol/commit/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](https://github.com/GDLev/mc-protocol/commit/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](https://github.com/GDLev/mc-protocol/commit/1fa4001)
- `helpers.forVersion()` binds the data-backed helpers (items, blocks, chunks and maps) to a protocol version. [d78fd31](https://github.com/GDLev/mc-protocol/commit/d78fd31)

## 17 September 2026

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

## 16 September 2026

- the project history was imported into this repository. this is where the git log starts. [cf5264e](https://github.com/GDLev/mc-protocol/commit/cf5264e)
- fix: protocol framing, connection lifecycle and wire encoding were corrected. [35d6031](https://github.com/GDLev/mc-protocol/commit/35d6031)
