@MartyG-RealSense , thanks for the announcement. There seems to be something missing. On release page (https://github.com/IntelRealSense/librealsense/releases/tag/v2.42.0) it recommends firmware 5.12.11.0, however, on firmware page (https://dev.intelrealsense.com/docs/firmware-releases) the latest one is 5.12.10.0.

Is this a typo, or should we wait for 5.12.11.0 a little more?
Thanks,
Akif

Hi @akifh New firmwares are bundled into the SDK that they are recommended for. So if you have SDK 2.42.0 installed, you can update the firmware in the 2.42.0 version of the RealSense Viewer program by going to the More option near the top of the Viewer's options side-panel and selecting from its menu the option Install Recommended Firmware. This should automatically update your camera to the new firmware without needing a firmware file.

The standalone bin file for a new firmware usually appears on the firmware download page within a week or so of its initial availability at the release of a new SDK version, so I recommend checking the firmware page occasionally to see when the latest firmware appears on it.

@MartyG-RealSense , thanks for the info. I will deploy the new firmware to a remote, headless system via rs-fw-update tool. Therefore, viewer etc. are not available, I need bin file. Then, we will wait for it to become available. Maybe, for upcoming releases, recommendations and firmware download page can be more synchronized.

Thanks,
Akif

[MartyG-RealSense]

My expectation would be that if you have the previous firmware 5.12.10.0 currently installed then it should still work for the 2.42.0 release.

[akifh]

@MartyG-RealSense , thanks, yes I think so. But this is something irrelevant with synchronization of both pages. As soon as a firmware is recommended officially, one should be able to use it with official rs-fw-update tool, without needing GUI tools etc.

Thanks,
Akif

[MartyG-RealSense]

@akifh I do understand your concern about release synchronization. Taking into account the logistics involved that may prevent day-one updates across all resources, Intel are agile in responding to a new librealsense release with updates for primary supporting components (websites, RealSense ROS wrapper, etc).

[ev-mp]

@akifh hello, the distribution method involves passing external hosting services, and, as pointed by @MartyG-RealSense , it may take certain time for all the release content to propagate.
Specifically for the new FW - running SDK's CMake locally will download the new image bin files, and those can be used immediately.

[akifh]

@MartyG-RealSense day-one updates may not be possible due to external services, yes, but "a week or so" was a bit long for me so I asked for better synchronization. Though, @ev-mp 's suggestion is sufficient for me at this point.

Thanks for all the replies,
Best,
Akif

@agrunnet @dorodnic @MartyG-RealSense Any update on external color synchronization for the D455 cameras? #7502

[smeng9]

Still no official release for latest python version? Disappointed and does not sound reasonable

[MartyG-RealSense]

@smeng9 2.42.0 includes the updates to pybind11 discussed in #8229 (comment)

Integrate pybind11 V2.6.1 + replace pybind11 files with clone action
Clone pybind11 instead of keeping pybind files inside librealsense2 repo
Update pybind version 2.2.1 -> 2.6.1

[smeng9]

Understand, but the pypi release will be much easier and helpful because we no longer need to build from source when deploying on multiple computers

[MartyG-RealSense]

@sam598 I have no details to provide about external color synchronization for the D455 cameras at the time of writing this.

Hi @akifh Firmware 5.12.11.0 is now listed on the firmware download page.

Edit: ROS1 wrapper 2.2.22 for SDK 2.42.0 has just been released.
