## [Unreleased]
## [1.0.0] - 2023-08-04
### Changed
- Introduce `std` (enabled by default) and `unstable` features ([#58]). They
enable corresponding serde’s features and if either is enabled, `Error`
implements `std::error::Error` trait. By itself, `serde-json-wasm` is now
`no_std`; it’s up to serde’s features whether the entire build is.<br/> **Please
note:** this potentially breaks `default-features = false` builds.
If you need the `Error` trait impl, enable one of the two features explicitly.
- Serialize / deserialize `u128`/`i128` types as numbers instead of strings
([#59]).<br/> **Please note:** this breaks deserialization of `u128`/`i128`
serialized with older versions of `serde-json-wasm`.
[#58]: https://github.com/CosmWasm/serde-json-wasm/pull/58
[#59]: https://github.com/CosmWasm/serde-json-wasm/pull/59
## [0.5.1] - 2023-04-11
### Added
- Add support for `collect_str` serialization ([#51], [#55]).
[#51]: https://github.com/CosmWasm/serde-json-wasm/pull/51
[#55]: https://github.com/CosmWasm/serde-json-wasm/pull/55
## [0.5.0] - 2022-12-06
### Added
- Add support for map (de)serialization.
- Add support for `#[serde(flatten)]` (de)serialization ([#20]).
[#20]: https://github.com/CosmWasm/serde-json-wasm/issues/20
### Changed
- Bump min supported Rust version to 1.59.0 (same as cosmwasm-std)
- Upgrade codebase to Rust edition 2021
## [0.4.1] - 2022-05-05
### Changed
- Properly serialize `u128`/`i128` types when embedded in structs
## [0.4.0] - 2022-03-29
### Added
- Add support for `#[serde(untagged)]` enums representation
## [0.3.2] - 2021-12-14
### Added
- Add support for u128/i128 serialization and deserialization ([#32],
[#33]).<br/> **Please note:** this is
[incompatible with serde-json and schemars](https://github.com/CosmWasm/cosmwasm/issues/1605)
and for this reason discouraged to use.

[#33]: https://github.com/CosmWasm/serde-json-wasm/pull/33
## [0.3.1] - 2021-01-19
### Added
- Add support for Unit () deserialization.
## [0.3.0] - 2021-01-14
### Changed
Maintenance release:
- Update clippy version in CI to 1.49.0.
- Fix `clippy::manual-non-exhaustive` warnings.
## [0.2.3] - 2021-01-14
### Changed
- Optimize string serialization / deserialization.
## [0.2.2] - 2021-01-13
### Added
- Add support for unit structs serialization / deserialization.
- Add support for tuple variants serialization / deserialization.
- Add support for unit serialization / deserialization.
## [0.2.1] - 2020-05-07
### Changed
- Remove unused Travis CI config
- Polish Cargo.toml
## [0.2.0] - 2020-05-07
### Fixed
- The end of strings is now detected correctly in deserialization (#11)
### Changed
- Strings are now escaped during serialization (#10)
- `from_str`/`from_slice` now work for `T: DeserializeOwned` instead of
`T: Deserialize<'de>`, making it impossible to deserialize into non-owned
reference fields. This is necessary since string unescaping requires creating
a mutated copy of the source data and only JSON strings without escape
sequences can be deserialized copy-free. The same limitation applies to
serde_json, where the problem shows up at
[runtime instead of compile time](https://github.com/serde-rs/json/issues/530).
- Strings are now unescaped during deserialization (#13)
## [0.1.3] - 2020-03-12
- Expose deserializer and serializer
## [0.1.2] - 2019-12-20
- Add newtype string support
## [0.1.1] - 2019-10-27
- Fix embeded enums
## [0.1.0] - 2019-10-27
