Strange that when I have CTF check for updates, it says:
ClickToFlash 1.5.3 is currently the newest version available.

Nevermind. I found this on the link you provided:
The current version is ClickToFlash-1.6b7-upload1.zip, but you may have go to the Github page for ClickToFlash to download it.

Jonathan Rentzsch explained that he hasn't been able to update it himself due to illness. However, given that it is open-source, four others (identified as ndfred, Justin, ssp and lapcat) identified the problem and a solution, and Rentzsch merged it back into the main branch of the code.
Thanks for the "heads up" on this.
