We are currently running ROCm version 2.7.1, and the last upstream version is 3.10 (https://rocm-documentation.readthedocs.io/en/latest/Current_Release_Notes/Current-Release-Notes.html).
While testing with @Miriam we found some bugs of the combination tensorflow-rocm / ROCm that we hope to see it fixed after the upgrade (worst case scenario we'll provide a bug report to upstream with their last version of the code).
Before starting, it is worth to point out that the new version will probably only support tensorflow-rocm 2.x. Waiting for @Miriam's green light before proceeding :)
