 - ``esp_vfs_dev_uart_use_driver`` has been renamed to ``uart_vfs_dev_use_driver``
 
 For compatibility, `vfs` component still registers `esp_driver_uart` as its private dependency. In other words, you do not need to modify the CMake file of an existing project.

+XMC-C series flash suspend support has been removed. According to feedback from the flash manufacturer, in some situations the XMC-C flash would require a 1ms interval between resume and next command. This is too long for a software request. Based on the above reason, in order to use suspend safely, we decide to remove flash suspend support from XMC-C series. But you can still force enable it via `CONFIG_SPI_FLASH_FORCE_ENABLE_XMC_C_SUSPEND`. If you have any questions, please contact espressif business support.

+XMC-C 系列闪存 suspend 功能的支持已被移除。根据闪存制造商的反馈，在某些情况下，XMC-C 闪存需要在 resume 和下一条命令之间间隔 1 毫秒。这对于软件请求来说时间太长。基于上述原因，为了安全使用 suspend 功能，我们决定取消对 XMC-C 系列闪存挂起的支持。但是你依旧可以通过打开 `CONFIG_SPI_FLASH_FORCE_ENABLE_XMC_C_SUSPEND` 来强行使能这个功能。如果您有任何疑问，请联系 espressif 商务支持。
