v1.10.0

Break Change

• [#464] Due to design bugs, we are sorry to warn you that some behaviors of ast.Node have to be changed:

  • BREAK CHANGE: ast.Unset() now WON'T change ast.Len() and ast.Index()
  • BREAK CHANGE: ast.UnsafeArray() and ast.UnsafeMap() are deprecated and user SHOULDN'T modify node based on these API

• [#393] Due to difficulty of maintaining compatibility with Golang:

  • BREAK CHANGE: sonic now only support Go 1.16~1.20, drop Go 1.15 support

Feature

• [#493] support Go1.21.0
• [#471] (ast) add ast.Visitor for transversing JSON in-place
• [#470] add Valid() API

Bugfix

• [#486] possible overflowed instruction while handling byte type
• [#484] (decoder) avoid scratched memory of returned error
• [#496] (ast) Exist() didn't check Valid() first
• [#498] (ast) drop ast.Node API UnsafeArray() and UnsafeMap() (Break Change)

Optimization

• [#393] refactor asm2asm to avoid SIGPROF crashing, and enable traceback when C function panics
• [#464] (ast) use linked chunk as fundamental storage for nodes to keep node pointer valid (Break Change)
• [#464] (ast) avoid malloc when meeting empty values, and inline header chunk into lazy-parsing stack to reduce malloc. The performance of Parse()\Load()\Interface() promoted 10~60%
• [#475] (last) pass skipnumber flag to avoid decoding numbers
