Changes in Version 2.0

  • The code has been re-written. It is now easier to read and follow; less of a mish-mash.
  • Support for native JSON has been included. This means that if you are using a browser that supports JSON.stringify, it will be used. Also evalJSONand secureEvalJSON will use JSON.parse if available.
  • Changes were made in the JSON output to move in line with the JSON object standard. This means 2.0 is not backwards compatible with the previous versions.
  • toJSON now renders like compactJSON used to and compactJSON does not exist anymore. As per the JSON object standard, needless spaces are now removed. This makes it less readable; if someone wants to send me a prettyJSON patch, it will be welcome.
  • Differences between output when JSON.stringify is available and when it is not could exist. I am unable to test all strings. Be aware when testing your apps.
