v0.5.2

• Enum variants can now be serialized by name. (#62 by @Freax13)

v0.5.1

• Fixes a performance regression in array serialization. (#61 by @caelunshun)

• Fixes an incompatibility with serde versions 1.0.119 and later. (#60 by @Iaiao)

v0.5.0

New Features

• Compiling with the preserve_order feature will use an IndexMap instead of a HashMap for compound tags, which preserves insertion order when serializing. (#54 by @samlich)

• Structs can now be explicitly told to serialize as byte/int/long arrays instead of a list under Serde by using serialize_with and the new i8_array(), i32_array(), and i64_array() functions. (#51, #52, and #53 by @Schuwi). For example:

#[derive(Serialize)]
struct MyStruct {
    #[serde(serialize_with="hematite_nbt::i8_array")]
    byte_array: Vec<i8>,
}

• Blob now has a len_bytes() method to compute the expected length when serialized, restoring functionality removed in #36. It turns out to be helpful to know the length when writing NBT payloads into network packets. (#48 by @ejmount)

• Blob now has a get() method to get values by name; previously this was only possible via indexing, which would panic if the key was absent. (#44 by @vlakreeh)

• Blob now implements Default::default(), as suggested by Clippy.

Bug Fixes and Other Improvements

• The flate2 dependency has been bumped to enable compilation for WASM. (#56 by @oOBoomberOo)

• The use of various deprecated APIs in the Rust standard library has been fixed, so consumers of this crate will no longer see build warnings. (#49 by @atheriel)

• UnrepresentableType will now correctly show the type in the error message, instead of the literal string $type. (#47 by @caelunshun)

• The benchmark suite has been rewritten to use Criterion, so it should compile with stable Rust. However, it's not clear that the black-box benchmarks are actually working properly at this time.

• The project now uses and enforces rustfmt rules.

v0.4.1

• Strings are now encoded and decoded using Modified UTF-8, matching the behaviour of the vanilla Minecraft client. This should only affect strings with codepoints outside of the Basic Multilingual Plane, which are likely quite rare in the wild. Note that we permissively handle true UTF-8 input, but always write MUTF-8 output. (#39)

• Serde-based deserialization now supports TAG_LongArray. (#41 by @caelunshun)

• Empty lists are now written with TAG_End as the list type instead of TAG_Byte. This matches the behaviour of the vanilla Minecraft client, although it should not in theory affect well-behaved NBT parsers.

• Fixes Serde-based serialization of empty lists.

• Updates the project README and adds a NEWS file.
