## Highlights
- **Multi-Document Parsing:** read a bundle of JSON documents (ndjson) 2-4x faster than doing it
- **Multi-Document Parsing:** Read a bundle of JSON documents (ndjson) 2-4x faster than doing it
individually. [API docs](https://github.com/simdjson/simdjson/blob/master/doc/basics.md#newline-delimited-json-ndjson-and-json-lines) / [Design Details](https://github.com/simdjson/simdjson/blob/master/doc/parse_many.md)
- **Simplified API:** The API has been completely revamped for ease of use, from the DOM API to
error handling and error chaining! [Docs](https://github.com/simdjson/simdjson/blob/master/doc/basics.md#the-basics-loading-and-parsing-json-documents)
- **Exact Float Parsing:** simdjson now parses floats flawlessly *without* any performance loss,
- **Simplified API:** The API has been completely revamped for ease of use, including a new JSON
navigation API and fluent support for error code *and* exception styles of error handling with a
single API. [Docs](https://github.com/simdjson/simdjson/blob/master/doc/basics.md#the-basics-loading-and-parsing-json-documents)

it will adjust automatically when it encounters larger files.
- Runtime selection API: We've exposed simdjson's runtime CPU detection and implementation selection
as an API, so you can tell what implementation we detected and test with other implementations.
- Error handling your way: Whether you use exceptions or check error codes, simdjson lets you handle
errors in your style. APIs that can fail return simdjson_result<T>, letting you check the error
code before using the result. But if you are more comfortable with exceptions, skip the error code
and cast straight to T, and exceptions will be thrown automatically if an error happens. Use the
same API either way!
- Error chaining: We also worked to keep non-exception error-handling short and sweet. Instead of
having to check the error code after every single operation, now you can *chain* JSON navigation
calls like looking up an object field or array element, or casting to a string, so that you only
have to check the error code once at the very end.
