v0.15.0

Language

• New stdlib functions:
  • std.member
  • std.clamp
  • std.stripChars, std.lstripChars, std.stripChars
  • std.flatMap
  • std.repeat

Interpreter (Go)

Runtime

• Greatly improved performance of multiple stdlib functions:
  • std.reverse
  • std.substr
  • std.base64, std.base64Decode, std.base64DecodeBytes
• Adaptive string representation - naively joining many short
  strings using operator + is now a linear operation.
• Fixed incorrect handling of overflow in bitwise operators.
• Tests should now pass on x86 and ARM.
• Unary + no longer allowed on objects.

API

• Fully compatible, experimental Python API is now available.
• Import cache is now preserved across evaluations, which
  improves performance when evaluating multiple files, which
  use the same libraries or when evaluating the same file with
  different TLAVars. Note that changing ExtVars still clears
  the cache, because they potentially affect every import.
• New public functions jsonnet.ResolveImport and
  jsonnet.ImportData for easier integration of tooling
  with importers.
• New public function toolutils.Children for easier traversing
  of AST.
• AST contains comments now, which allow building code transformation
  tooling.

Interpreter (C++)

• Fixed incorrect error message, when too few arguments are provided
  for string formatting.
• Fixed a dangling pointer, which could have potentially caused crashes.
