- The ``psram_trans_align`` and ``sram_trans_align`` members in the :cpp:type:`esp_lcd_rgb_panel_config_t` structure have also been replaced by the :cpp:member:`esp_lcd_rgb_panel_config_t::dma_burst_size` member for configuring the DMA burst transfer size.
- The ``color_space`` and ``rgb_endian`` configuration options in the :cpp:type:`esp_lcd_panel_dev_config_t` structure have been replaced by the :cpp:member:`esp_lcd_panel_dev_config_t::rgb_ele_order` member, which sets the RGB element order. The corresponding types ``lcd_color_rgb_endian_t`` and ``esp_lcd_color_space_t`` have also been removed; use :cpp:type:`lcd_rgb_element_order_t` instead.
- The ``esp_lcd_panel_disp_off`` function has been removed. Please use the :func:`esp_lcd_panel_disp_on_off` function to control display on/off.
- The ``on_bounce_frame_finish`` member in :cpp:type:`esp_lcd_rgb_panel_event_callbacks_t` has been replaced by :cpp:member:`esp_lcd_rgb_panel_event_callbacks_t::on_frame_buf_complete`, which indicates that a complete frame buffer has been sent to the LCD controller.
- The ``on_bounce_frame_finish`` member in :cpp:type:`esp_lcd_rgb_panel_event_callbacks_t` has been replaced by :cpp:member:`esp_lcd_rgb_panel_event_callbacks_t::on_frame_buf_complete`, which indicates that a complete frame buffer can be safely reused.
- The LCD IO layer driver for the I2C interface previously had two implementations, based on the new and legacy I2C master bus drivers. As the legacy I2C driver is being deprecated, support for it in the LCD IO layer has been removed. Only the APIs provided in ``driver/i2c_master.h`` are now used.
- ``pixel_format`` member in the :cpp:type:`esp_lcd_dpi_panel_config_t` structure has been removed. It is recommended to only use :cpp:member:`esp_lcd_dpi_panel_config_t::in_color_format` to set the MIPI DSI driver's input pixel data format.
- ``bits_per_pixel`` member in the :cpp:type:`esp_lcd_rgb_panel_config_t` structure has been removed. The color depth of the internal framebuffer is now determined by the :cpp:member:`esp_lcd_rgb_panel_config_t::in_color_format` member.

- :cpp:type:`esp_lcd_rgb_panel_config_t` 结构体中的 ``psram_trans_align`` 和 ``sram_trans_align`` 均已被 :cpp:member:`esp_lcd_rgb_panel_config_t::dma_burst_size` 成员取代，用来设置 DMA 的突发传输大小。
- :cpp:type:`esp_lcd_panel_dev_config_t` 结构体中的 ``color_space`` 和 ``rgb_endian`` 配置均已被 :cpp:member:`esp_lcd_panel_dev_config_t::rgb_ele_order` 成员取代，用来设置 RGB 元素的排列顺序。对应的类型 ``lcd_color_rgb_endian_t`` 和 ``esp_lcd_color_space_t`` 也已被移除，请使用 :cpp:type:`lcd_rgb_element_order_t` 替代。
- ``esp_lcd_panel_disp_off`` 函数已被移除。请使用 :func:`esp_lcd_panel_disp_on_off` 函数来控制显示内容的开关。
- :cpp:type:`esp_lcd_rgb_panel_event_callbacks_t` 中的 ``on_bounce_frame_finish`` 成员已被 :cpp:member:`esp_lcd_rgb_panel_event_callbacks_t::on_frame_buf_complete` 成员取代，用于指示一个完整的帧缓冲区已被发送给 LCD 控制器。
- :cpp:type:`esp_lcd_rgb_panel_event_callbacks_t` 中的 ``on_bounce_frame_finish`` 成员已被 :cpp:member:`esp_lcd_rgb_panel_event_callbacks_t::on_frame_buf_complete` 成员取代，用于指示一个完整的帧缓冲区可以被安全复用。
- I2C 接口的 LCD IO 层驱动有两套实现，分别基于新、旧 I2C Master 总线驱动。由于旧版的 I2C Master 驱动逐渐被弃用，遂 LCD 的 IO 层也移除对旧版的支持，只使用 ``driver/i2c_master.h`` 中提供的 API。
- :cpp:type:`esp_lcd_dpi_panel_config_t` 结构体中的 ``pixel_format`` 成员已经被删除。建议仅使用 :cpp:member:`esp_lcd_dpi_panel_config_t::in_color_format` 来设定 MIPI DSI 驱动输入的像素数据格式。
- :cpp:type:`esp_lcd_rgb_panel_config_t` 结构体中的 ``bits_per_pixel`` 成员已经被删除。内部帧缓冲区的色彩深度现在由 :cpp:member:`esp_lcd_rgb_panel_config_t::in_color_format` 成员决定。
