We are currently on R 2.0.0 alpha. If you submit a bug fix, preferably this week and at the latest next week, it will be considered for 2.0.0.
Please take seriously that R is an open project and does not have `staff' to fix bugs. If you think it is worth fixing, please fix it for us by providing a complete analysis and fixes for all the possible options that might be affected. The best place for a patch to be sent is R-bugs.
