Nobody noticed, with regard to HPE OfficeConnect 1920S Switch Series, that HPE OfficeConnect Support Portal was not updated with latest PD.01.07 Firmware built (December 2017)?
The page related to HPE OfficeConnect 1920S Switch Series on the HPE OfficeConnect Support Portal still reports the PD.01.06 (June 2017) as latest Firmware build available for the entire series.
Sadly, as of today, related Release Notes document appears to be not yet available...maybe the download URL will be fixed soon.
The new PD.01.07 may (or may not) solve some issues reported recently on HPE Community about the HPE OfficeConnect 1920S Switch Series (as example the one reported here) but, without PD.01.07 Release Notes, it's hard to tell if that will be true or not.
Edit: gosh, discovered that the HPE OfficeConnect Support Portal was not kept up-to-date also with regard to HPE OfficeConnect 1950 Switch series...latest build reported is R3116 of June 2017 when, instead, the R3116P05 is available since October!
