Since we don't have a dedicated thread for regressions introduced with the initial merge of the cairo-rendering branch and I don't want to mix it with reports about merge of the rendering cache or the removal of libnr, I'm starting a new thread forwarding related confirmed reports in the bug tracker which haven't been mentioned on the list before:
Bug #845153 https://bugs.launchpad.net/inkscape/+bug/845153 "radial gradients not rendered correctly"
Bug #837066 https://bugs.launchpad.net/inkscape/+bug/837066 "Bucket Tool regressions with Cairo renderer"
Bug #814179 https://bugs.launchpad.net/inkscape/+bug/814179 "CMS tab: Yellow and Cyan colors are swapped"
Bug #805392 https://bugs.launchpad.net/inkscape/+bug/845153 "Circle resizing do not preserve stroke width"
