What’s Included in the New Panasonic Firmware Update

This update might not include headline-grabbing features like the G9 II firmware earlier this year, but it’s focused on something important: improving reliability and security. Panasonic says the update enhances how the camera handles Bluetooth, Wi-Fi, USB connections, and communication with Lumix mobile apps.

These are the two main areas of this update:

1. Improved Security:

Panasonic says this update helps protect your camera from potential vulnerabilities—like unauthorized access or data interception—especially when connecting to networks or smart devices.

2. Better Operational Stability:

You should see fewer bugs, crashes, or hiccups. Whether you're shooting stills or video, you're expected to experience more stable and reliable performance.

Some GH5 II users have noted that certain features disappeared after updating. Panasonic has confirmed these removals were intentional and part of improving the camera’s security protocols.
