Although the survey documentation indicates that SkyView has been using the SDSS DR9, it has been using the DR8 data internally. The main difference is that there are some astrometric corrections in the DR9. The releases since the DR9 have not affected the imaging survey.
The SkyView web site should now be using the DR9 and we will be releasing a new SkyView -in-a-Jar shortly. Our apologies for the error.
