# v3.0.0
|
|
|
|
Released on 2017-12-17.
|
|
|
|
First 3.x release — a major release with breaking changes (see the
|
|
[migration guide](../../integration/migration_guide.md)).
|
|
|
|
- Introduces user-defined [exceptions](../exceptions.md) (`json::exception` and subtypes, each with an
|
|
identifier).
|
|
- Adds a non-throwing [`accept`](../../api/basic_json/accept.md) function and an `allow_exceptions` flag
|
|
for [`parse`](../../api/basic_json/parse.md), and an [`update`](../../api/basic_json/update.md) function to
|
|
merge objects.
|
|
- Adds streaming for CBOR and MessagePack and allows storing NaN/infinity.
|
|
- Non-UTF-8 strings now throw on serialization, and the iterator category changed to bidirectional.
