Panasonic has released new firmware for the Lumix DMC-GH4 camera, its 42.5mm f/1.2 portrait lens and the 30mm f/2.8 macro. The firmware was introduced the same day as the V2.0 for the Lumix DC-GH5, but was rather over-shadowed by the bigger news (for obvious reasons). That doesn’t mean it’s not worth mentioning though.
On the camera side, the update for the GH4 fixes an issue that prevented image stabilization from functioning with some third party lenses when working in the variable frame rate video mode.
For the lenses, the update brings Dual IS 2 to both the (H-HS030) Lumix G Macro 30mm f/2.8 ASPH Mega OIS and (H-NS043) Leica DG Nocticron 42.5mm f/1.2 ASPH Power IOS lenses, with individual updates for each of the models.
The version 2 of the stabilization system that combines in-camera sensor movement with in-lens anti-shake units is said to provide better performance for stills shooters as well as stabilization in movie mode and 4K/6K Photo modes via a new gyro system in Dual IS 2 compatible bodies. At the moment only the DC-GH5 and G80/G85 support the system, which differs from the Dual IS modes used in the GX8 and GX80/85.

Panasonic also publishes a chart that shows the version of Dual IS each lens/body combination will deliver.
