Hi

Every time I try to clean build my project, I am flooded with these warnings:

It is rather annoying, and it would be great if these could be patched. Thanks!

No, I have zero intention to remove those unused variable warnings.

v2.9.9 is two years old. Yes, it is about time that I issue a new Release. I have been saying this for at least the last year.

Hi, so is there anything that will be done about it? And what and when will be the new release?
