版本发布特性说明

Atlas 200I DK A2开发者套件于2023年8月3日发布最新版本，建议升级到最新版本，软件功能更强，接口功能更丰富。

2023年8月3日版本（23.0.RC2）更新说明

Atlas 200I DK A2开发者套件2023年8月3日发布版本变更说明如表1所示。

表1 特性变更说明
特性名称	变更类型	变更说明
镜像文件	新增	USB接口新增连接音频设备功能。 USB接口新增WIFI连接功能，可使用USB接口的WIFI信号接收器（默认仅支持RTL 8192CU型号的芯片）无线连接到路由器。内置图形桌面驱动和LXQT桌面系统，用户直接将显示器通过HDMI接口连接开发者套件即可使用可视化桌面。新增VNC远程桌面登录功能（默认使用XFCE桌面系统）。
	修改	ssh远程登录的欢迎文字修改为开发者套件专属欢迎文字。默认安装v4l-utils依赖，使用USB摄像头功能无需再手动下载该软件。默认安装sympy，使用atc转模型无需再手动下载该三方库。删除默认用户ubuntu与CustAiCpuUser，若用户需要则自行添加。 miniconda安装路径从/root/改成/usr/local/，对用户使用无影响。后续不再更新E2E镜像，同时在基础镜像中增加E2E扩展功能安装脚本（含下载扩展包与安装功能）。烧录镜像默认已创建8G容量的swap交换分区，用户无需再手动创建。补回/etc/fstab文件。开发者套件启动速度提升。
	修复	修复了使用ATC工具转模型时，引用库文件libstdc++.so.6提示缺少GLIBCXX_3.4.30的问题
一键制卡工具	新增	支持在线升级。支持制卡后，对SD卡当中的镜像进行网络信息的配置。
模型适配工具	新增	支持在线升级。预置的三个模型（MobileNetV3、Yolov5、UNet++）支持INT8量化。模型训练过程支持提前停止。
E2E场景化样例	新增	新增机器狗样例：支持运动控制、自动循线运动、特定目标跟随。机械臂样例增加一键增加环境配置的脚本。
推理参考样例	新增	20个推理参考样例。 https://gitee.com/ascend/ascend_community_projects/tree/310B/SpeechRecognition https://gitee.com/ascend/ascend_community_projects/tree/310B/ALSA-Audio https://gitee.com/ascend/ascend_community_projects/tree/310B/MoveitMechanicalArmSimulation https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/2_object_detection/YOLOV4_coco_detection_car_video https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/2_object_detection/YOLOV3_mask_detection_picture https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/3_segmentation/unet++ https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/2_object_detection/YOLOV4_coco_detection_car_picture https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/1_classification/inceptionv3_picture https://gitee.com/ascend/ascend_community_projects/tree/310B/RosSdkInfer https://gitee.com/ascend/samples/tree/master/python/level2_simple_inference/1_classification/googlenet_onnx_picture https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/FatigueDrivingRecognition https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/OpenposeKeypointDetection https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/VehicleCounting https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/VehicleIdentification https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/CartoonGANPicture https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/EfficientDet https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/FastSCNN https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/PraNetSegmentation https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/TextSnake https://gitee.com/ascend/mindxsdk-referenceapps/tree/310B/contrib/RoadSegmentation
