Oracle recently published the first release of ODSEE, Oracle Directory Server Enterprise Edition 11g Release 1 (11.1.1), formerly known as Sun Directory Server Enterprise Edition 7.0 (DSEE 7). ODSEE 11.1.1 simply corresponds to the first patch for DSEE 7, so one can see it as DSEE 7.0P1 or DSEE 7.1, as you want !
This is only a "bug fix" release, there's no new feature.
