AMD ROCm 5.4.2 Released As Another Small Update To The Compute Stack
Sadly, as is all too often the case for AMD point releases, there aren't any accompanying change-log that specifically outlines what has been changed with this minor revision.
The new 5.4.2 documentation doesn't provide any change-log or any substantive difference over the earlier 5.4 updates.
RHEL/CentOS 8 and 9, SUSE Linux Enterprise 15 SP4, and Ubuntu 20.04.5 LTS / Ubuntu 22.04.1 LTS remain the supported Linux distributions by the Radeon Open eCosystem stack.
The officially supported hardware by ROCm remains the Radeon Instinct MI50/MI60, Radeon VII, Radeon Pro VII, Radeon Pro W6800 series, Radeon Pro V620, and Instinct MI100/MI200 hardware. There's nothing to report yet on official RDNA3 support for ROCm.
