[aur-general] Submit package with different version

Hi, 1) I want to submit a pkgbuild for csound5, release 5.10, but I'm not able because another one exists for csound5, release 5.09. My package is not just a minor update to the previous one, so simply commenting the 5.09 version is out of question. How should I do this then? 2) At some moment I uploaded a csound51 package just to try and then I found out that I was unable to delete it. Could you please remove this package? Best regards -Carlos
