SiLabs Gecko SDK 5.0.0.0 + Silicon Labs Simplicity SDK Suite 2024.6.0 has been announced and to be released soon and support for EZR32/EFM32/EFR32 Series 0 and Series 1 devices been removed

Just a heads-up, sounds as if Silicon Labs is phasing out Z-Wave 700 and older by only including Z-Wave 800 in the new SDK versions.

FYI, Silicon Labs Gecko SDK 5.0.0.0 + SiLabs Simplicity SDK Suite 2024.6.0 been announced (but not yet released but will very soon?):

Gecko SDK 5.0 seems to be scheduled to be released very soon as Q2/2024 (June 2024) is specifically mentioned as the release date:

Perhaps most noteworthy is that SiLabs Gecko SDK 5.0 / 5.x has removed support for EZR32/EFM32/EFR32 Series 0 and Series 1 devices.

Gecko Platform 5.0 will remove support for EFR32 Series 0/1 (e.i. EFR32MGx and EFR32MG1x) so need to use separate SDKs for Series 0 & 1 and Series 2 & 3 Starting in Q2 2024 (June 2024) as the new Gecko Platform and SDK are designed specifically for our EFR32 Series 2 and upcoming Series 3 devices only.

It is however still unclear to me which specific Z-Wave SoC chips will not be supported in Gecko Platform 5.x and newer versions.

If I understand it then it sounds like only Z-Wave 800 Series SoCs will be supported in SiLabs Gecko SDK 5.0 / 5.x platform versions?

So only Z-Wave 800 will be supported in Z-Wave SDK version 7.22.0.0+ while Z-Wave 700 and older will only continue in 7.21.x.x?

Also newly released are Z-Wave and Z-Wave Long Range 800 version 7.22.0.0 which changelog says something along those lines.

If so then it means Z-Wave 700 and older SoCs will continue with 7.2x.x.x as long-term support for bug-fixes but not get new features?

FWIW, Simplicity SDK is already released and available within Simplicity Studio.

Also I don't think Gecko SDK will be released as version 5. The links above mention Gecko Platform 5.0, which is serviced by Simplicity SDK.

Not sure about their versioning plans. Limiting 700 series to 7.21.x sounds like they'll only receive patch releases, but then I didn't have the impression that the firmware versions follow SemVer anyways.
