- Release date: 2016-06-28 - SHA-256: ef550fcd7df572555bf068e9ec4e9d3b9e4cdd441cecb0dcea9ea7fd313f72dd This release fixes a performance regression in the JSON serialization (function `dump()`). This fix is backwards compatible. - The locale of the output stream (or the internal string stream if a JSON value is serialized to a string) is now adjusted once for the whole serialization instead of for each floating-point number. - The locale of an output stream is now correctly reset to the previous value by the JSON library.
