Where is the source code for the Websocket plugin

Hi everyone,

First time in this forum. I checked out source code of the release version for OF 10.0.3 . But i found no code related to the websocket plugin at all. I have to install this plugin from the .jar file. It's got a jar file, so there must be source code for version 3.10. Where do i find that source code?

If you checkout the branch 3.10, you can't find websocket plugin in the src/plugins/ folder. But it's there in master branch.

Am i missing something? I need to hack the 3.10's source code.

Best regards
