Jansson 2.2.1 released

Jansson 2.2.1 has been released. This release fixes a major bug and little documentation and style issues.

The bug has to do with locales: Jansson's encoder and decoder both failed hard on real numbers when the locale's decimal separator was not the standard one. Furthermore, the decoder issued invalid error messages in some cases under non-UTF-8 locales.

The full release notes are available here.
