Linuxeden开源社区由于意外地收到了Google一名工程师的PR（https://github.com/Neeke/Jsonnet-PHP/pull/6），Jsonnet-PHP发布了1.3.1版本。
此次PR内容为：
- Fixed capitalization: JsonNet -> Jsonnet
- Added language directive for syntax highlighting code snippets
- Removed extra indent whitespace around code samples for readability
- Minor wording changes for readability
- Added link to Jsonnet homepage for more info
可以看到 1.3.1 主要是将 JsonNet 修改为 Jsonnet，并对代码的格式进行了修改以提升可读性。
JsonNet-PHP 是 Google Jsonnet 对 PHP的支持扩展.
