This release **fixes a locale-related bug in the parser**. To do so, the whole number handling (lexer, parser, and also the serialization) have been overworked. Furthermore, a lot of small changes added up that were added to this release. All changes are backward-compatible.

- :bug: Locales that have a different character than `.` as decimal separator (e.g., the Norwegian locale `nb_NO.UTF-8`) led to truncated number parsing or parse errors. The library now has been fixed to work with **any locale**. Note that `.` is still the only valid decimal separator for JSON input.
- :bug: Numbers like `1.0` were correctly parsed as floating-point number, but serialized as integer (`1`). Now, **floating-point numbers correctly round trip**.
- :bug: Parsing incorrect JSON numbers with leading 0 (`0123`) could yield a [buffer overflow](https://github.com/nlohmann/json/issues/452). This is fixed now by detecting such errors directly by the lexer.
- :bug: Constructing a JSON value from a pointer was incorrectly interpreted as a Boolean; such code will now yield a compiler error.
- :bug: Comparing a JSON number with `0` led to a comparison with `null`. This is fixed now.
- :bug: All throw calls are now wrapped in macros.
- :lock: Starting during the preparation of this release (since 8 February 2017), commits and released files are **cryptographically signed** with [this GPG key](https://keybase.io/nlohmann/pgp_keys.asc?fingerprint=797167ae41c0a6d9232e48457f3cea63ae251b69). Previous releases have also been signed.
- :sparkles: The parser for MessagePack and CBOR now supports an optional start index parameter to define a byte offset for the parser.
- :rotating_light: Some more warnings have been fixed. With Clang, the code compiles **without warnings** with `-Weverything` (well, it needs `-Wno-documentation-unknown-command` and `-Wno-deprecated-declarations`, but you get the point).
- :hammer: The code can be compiled easier with many Android NDKs by avoiding macros like `UINT8_MAX` which previously required defining a preprocessor macro for compilation.
- :zap: The unit tests now compile two times faster.
- :heavy_plus_sign: [Cotire](https://github.com/sakra/cotire) is used to speed up the build.
- :pencil2: Fixed a lot of typos in the documentation.
- :memo: Added a section to the README file that lists all used [third-party code/tools](https://github.com/nlohmann/json#used-third-party-tools).
- :memo: Added a note on constructing a string value vs. parsing.
- :white_check_mark: The test suite now contains 11202597 unit tests.
- :memo: Improved the [Doxygen documentation](https://nlohmann.github.io/json/) by shortening the template parameters of class `basic_json`.
- :construction_worker: Removed Doozer.
- :construction_worker: Added Codacity.
- :arrow_up: Upgraded Catch to version 1.7.2.
