Where I can find that the new release (version) was released? Detection in backend dont work.
I have now Book It2.0.0.

Hello,

I am sorry for late response. Version 2.0.0 contains bug. It doesn't show that there is new version.
You can download new version in Download Area.

Fill there your download_id and then it will start to download package with actual version. It is 2.0.2 ant there are these problems already solved. You should be able to check that there is new version in Control Panel of the component.

Update can be done in Check Updates page in Control Panel and tab Configuration.
