Maixpy

New Features
* Add WiFi AP mode API and demo(in `MaixPy/examples/tools` directory)
* Now USB driver (virtual network card) can be auto recognized by Windows and MacOS and Linux, no need to install driver manually anymore!
* Add USB setting in settings APP, you can select device mode or host mode(can use external USB devices like USB camera), and virual network card selection.
* Add timezone setting API and setting item in settings APP, and you can also find demo in `MaixPy/examples/tools` directory.

Optimization
* [optimize app.switch_app ignore same app switch](https://github.com/sipeed/MaixCDK/commit/3fd0701f0cfbbabea4a3ee0766a6c8a005965b4c)
* Optimize runtime installation to ensure old system use old runtime.
* Optimize MaixPy upgrade UI, now you can exit without stuck.
* Optimize builtin find_blob APP blue color threshold to find more blue color.
* Increase kernel memory to 128MB, so now user space memory is 128MB(the 4.4.19 is 160MB) for better camera driver stability.
* Add depracate warning to v1 API and optimize v1 examples' test image path.

BUG Fix
* NN memory leak issue when use dual_buff mode.
* Fix UART0 Tx pin write data error sometimes.
* [Fix morph bug](https://github.com/sipeed/MaixCDK/commit/1069419a75c7a616b205654efb50e72c944c81f6)
* Fix camera reopen bug.
* Fix desktop-monitor APP run failed error.


Attention

**You must to burn system image(`*.img.xz` file below) to use this version because it have camera driver update in system, and don't forget to install runtime in first bootup, old version system DO NOT upgrade runtime**
**你必须烧录系统镜像(下面的`*.img.xz`文件），以及第一次开机后记得安装运行库，才能正常使用此版本**

Bug Fix

* Cancel camera default 80fps mode, cause some camera not support this freq, if you want to use 80fps mode, set it in `camera.Camera(320, 240, fps=80)`
* Camera add_channel bug fix
* UART read function param `len` bug fix
* Limit app desc must one line when app_store installing app

New Features
* Add MaixHub client APP, now you can collect dataset by this APP and directly upload to MaixHub, and deploy model to MaixCAM in one click.
* Add `image.Image.set_windowing` function.
* Support now global shutter camera sms_sc035gs (only support 60FPS mode now, later will support 180fps~240fps)
* Support 5 inch screen, and 7inch touchscreen, buy [here](https://item.taobao.com/item.htm?spm=a1z10.1-c-s.w21412213-24984936557.35.5a6752b1Fv7lsZ&id=610352268976&skuId=5688232998030)

Optimization
* Camera(GC4653) now default support 80FPS mode, if you want to use 30 or 60 fps, set `fps=30` or `fps=60` when construct `camera.Camera` object.
* Change `image.Image.awb_mode` to `image.Image.set_awb` function.

Bug Fix
* Fix camera image buffer error.
* Fix cv2image grayscale image error

New Features

* i18n now support load from yaml dict files.
* Camera APP support record video(mp4 format), you can find video in `/maixapp/share/video` directory of device.

Optimization

* Camera(GC4653) support 60FPS mode now, and now fefault 60FPS(only support when resolution <= 720p).
> 60FPS mode's color has some different with 30FPS mode, if you want to use 30FPS mode, please set `fps=30` in `camera.Camera()`.
* AI model(NPU) support dual_buff mode and set it to default, now runing faster twice than before.
> dual buff mode enabled by default, if you want to disable it, set arg `dual_buff = False` when initilize model like `nn.YOLOv5(model="“, dual_buff=False)
* APP bootup/switch faster now.
* YOLOv5 and YOLOv8 object coordinate now ensure all value >= 0.
* `disp.set_backlight(0)` now will close backlight now.


BUG Fix

* Setting install runtime success but always show not install bug.
* Face recoginizer run fail bug.
* image.cv2image and image.image2cv memory leak bug
* RTSP optimize, now you can play it with `ffplay rtsp://10.228.104.1:8554/live` or `mpv rtsp://10.228.104.1:8554/live`
