S5148F-ON Multicast Routing support?

In the OS 10.4.3.0 user guide there's an important note to say "OS10 does not support multicast routing on S5148F-ON".

In the latest OS user guide there's no note in the multicast section of the user guide. There are also no notes in the OS 10.5 release notes to state whether a fix has been implemented. The latest datasheet that I have for the S5148F has no mention of multicast routing (IGMP or PIM) support.

Has multicast routing been implemented on the S5148F?
