Why no one review this?

I would like to, but I am not familiar with the code base. I am waiting for @chrox to review since he also manages the release :)

Are you interested in being a maintainer of this project?

[cytown]

OK, why not:) I hope we can find few useful cool features for this one...

[houqp]

Awesome, I will send you an email soon.

[chrox]

Looks good to me. Thanks. 👍

@cytown we have also given you write access to this repo so you can help maintain it in the future :) Look for github invite in your inbox.

When I tried to install the version 0.6.5 using mrinstaller ,it kept showing destroying packages. No problem with 0.6.4. Firmware version is 5.8.9. Am I the only one encountering this problem ?

[cytown]

Did you use upgrade? Or fresh install? Please try uninstall and clear install.

[DesertHuYang]

I've tried both.
Now I found the last hint is "not targeting your device " or something.
Can you please fix it :) ?
My device is kt3.

[cytown]

Please try this one, and check the message.

If still happen, maybe I am using wrong package tool or wrong command to package it.

Thanks. I will try again.
Sorry but it's still the same. The earlier version is okay. You may get more feedbacks from other users and fix the problem in next release.
