• Add optional dependency for jason_native. Please refer to the repo for usage instructions

• Use the :erlang.float_to_binary(_, [:short]) function, instead of io_lib_format.fwrite_g/1 where available (OTP 24.1+). This provides equivalent output with much less memory used and significantly improved performance.

• Add the Jason.OrderedObject struct
• Support decoding objects preserving all the keys with objects: :ordered_objects option
• Support decoding floats to Decimal with floats: :decimals option
• Add ~j and ~J sigils in module Jason.Sigil to support writing JSON literals in code

• Fix error reporting when decoding strings (it was possible to mis-attribute the offending byte)
• Verify fields given to @derive

• Support Decimal 2.0

• Fix html_safe escaping in Jason.encode

  The <!-- sequence of characters would not be escaped in Jason.encode withhtml_escape mode, which could lead to DoS attacks when used for embedding of arbitrary, user controlled strings into HTML through JSON (e.g. inside of <script> tags).

  If you were not using the html_safe option, you are not affected.

  Affected versions: < 1.2.1 Patched versions: >= 1.2.1
