There are release candidates for R 2.6.1 that is expected to be release next Monday (26). Those daily release candidates are placed here http://cran.r-project.org/src/base-prerelease/ I think that we could push those release candidates to updates-testing to detect earlier problems. In any case we have to deal in the first push of the new version with the dependency of rpy. Regards, -- José Abílio
