What is ' Issue 36: Introduce optional variables' in the Camunda-Camel extension?

Does anyone know why this commit happened; https://github.com/camunda/camunda-bpm-camel/commit/87322c859fc581b43b1ceaabc618c5abe70203b6 ?
The commit is part of pull request 37 (https://github.com/camunda/camunda-bpm-camel/pull/37 ), which is titled ’ Issue 36: Introduce optional variables’

When I upgrade to use this version of the library, all my variables have a query character appended to the end of their names, which stops all my Camel routes from executing correctly.

Thanks

Hi @NickTheArchitect,

I recommend you raise an issue on the github issue tracker of the extension.

Cheers,
