package jsont

v0.3.0 2026-08-14 Zagreb

• Add Jsont.Json.remove_mem[']
• Fix nested out-of-order case member decodes (#14)

• Fix Jsont.{int,int64}. The range in which numbers are codec by a JSON number is changed from [-2^53;2^53] to [-2^53+1;2^53-1] which is the correct range for reliable integer interchange.

  While 2^53 is the maximal integer that can be represented exactly, it is ambiguous as it shares its representation with 2^53+1. This means you could decode a JSON number 2^53+1 as 2^53. jsont did however encode 2^53+1 as a string so it was lossless on your own data.

  The new behaviour entails that both -2^53 and 2^53 values are now encoded as a string rather than a number. If you have encoded these numbers with the the previous version of Jsont.{int,int64} they will not parse back: they are now expected to be encoded by a string. You can use Jsont.legacy_{int,int64} to migrate your data, the decoding works as before (and thus remains wrong if they hit externally produced JSON numbers -2^53-1 and 2^53+1) but the encoding uses the new range.

  Thanks to Thomas Gazagnaire for the report (#18).

v0.2.0 2025-07-25 Zagreb

• Fix Jsont_bytesrw.{encode,encode'}. Do not write the eod slice if eod:false is specified. Thanks to Benjamin Nguyen-Van-Yen for the report and the fix (#8).
• Fix Jsont.zero failing encodes rather than encoding null as advertised. Thanks to Adrián Montesinos González for the report (#6).
• Add Jsont.Error.expected to help format error messages.
• Add Jsont.with_doc to update kind and doc strings of existing JSON types.
• Add Jsont.Object.Case.{tag,map_tag} to access a case and case map tags.
• Fix META file. Really export all requires and remove uneeded bytesrw dependency from jsont library.

• Jsont.Object.Mems.map make encoding and decoding optional. Like in every other map.
• Jsont.Array.map make encoding and decoding optional. Like in every other map.
• Jsont_bytesrw.encode change the default buffer size to match the one hinted by the writer rather than Bytesrw.Bytes.Slice.io_buffer_size.
• jsont.{bytesrw,brr} export all requires.
• jsont tool remove spurious dependency on b0.std (#2).
