  • Inf is emitted as .inf.
  • -Inf as -.inf.
  • NaN as .nan.
  • TRUE is now emitted as yes, and FALSE as no.
• Because the YAML specification does not specify how to handle NA values, the various NA types are emitted as follows:

• Fixed solaris compilation error.
• Removed printf/assert symbols from the compiled library.

yaml 2.1.0

• Rewrote as.yaml in C (using libyaml’s emitter).

yaml 2.0.0

• Switched from the Syck parser to the libyaml (0.1.4) parser.
• Sequences of sequences no longer collapse when they contain the same type; ex: yaml.load("[1, [2, 3], 4]") returns list(1L, c(2L, 3L), 4L).
