I wrote "Udev" because it appears at the first of the sentence.

OK. But in this page, https://linux.die.net/man/8/udev
"udev provides a dynamic device directory containing only the files for actually present devices."
They have used "udev" at the starting. Therefore, I had this doubt.

So, should we change it to "udev"?

It means that native (p/invoke) functions called by C# ImageUtil API are deprecated, so I changed it to newly added native functions.
I've thought about this sentence again, and I think it can be removed.
Please simply remove this sentence.

We need to add (omitted by mistake):

- Inference API set
  - It supports TensorFlow-lite (.tflite) and custom C (.so) models. In Tizen 5.5, TensorFlow (.pb) and nnfw-runtime models are not supported.

Hello.

I have some queries with latest version.
Would you please check?

- Support for the custom launching window transition effect has been added. It allows the launcher application to perform various custom launching animation effect instead of the enlightenment display server through tizen-ws-shell.
- Support for the seamless widget transition effect has been added. It supports seamless widget animation between one window to another window. Seamless animation is an animation that seamlessly transits from one window (occupying the current screen) to the other window (will occupy the next screen) and looks like a transition effect is running only on one window.
- The 'focus_policy_ext' configurable property has been added to support the window focus policy selection.

I'm not sure with line 496.
Is the the line line 496 intended below?

  • Support to distinguish CMAS public safety alerts, public safety alerts for an additional language, State/local WEA tests, and State/Local WEA test for an additional languages have been added to message service.

Or, it looks it'd be compatible to add below list under line 495, with removing this line.

  • Support for alerts from 4396 ~ 4399 has been added to the message API set.
    • 4396 : CMAS public safety alerts
    • 4397 : Public safety alerts for additional language
    • 4398 : State/local WEA tests
    • 4399 : State/Local WEA test for a additional languages.
