MicroPython在这个版本中增加了对使用CMake作为构建系统的通用支持。RP2移植被合并以使用新的CMake文件，esp32和zephyr移植已切换为纯CMake项目。这三个移植都有围绕CMake构建的SDK，这一更改使它们更易于维护和使用。
作为这项工作的一部分，基于CMake的移植现在支持用户C模块。用户C模块的作者应该同时提供.mk和.cmake配置文件（遵循文档和示例）。
修复了多精度整数库中的一个错误，即长除法例程中的算术溢出。在此修复之前，某些整数除法将花费大量时间并产生不正确的结果。有关详细信息，请参见提交0a59938。此外，还修复了正则表达式，在编译表达式时检查和报告字节溢出错误。参见172fb52。
在uasyncio库中，添加了一个新的MicroPython扩展ThreadSafeFlag，它可以从asyncio事件循环外部进行设置，例如从其他线程、irq或调度程序上下文。它允许像irq这样的抢占式代码中向asyncio任务发送信号，这些任务本质上是协作的（非抢占式的）。asyncio.current_task() 也已添加，语义与CPython相同。
如上所述，esp32移植已切换到基于CMake的完整项目，传统的make功能已被删除（尽管仍保留一个简单的helper Makefile，以使顶级构建/部署命令与其他移植保持一致）。因为切换到 CMake，network.LAN 支持已被删除，并将在以后重新添加（如果需要LAN，请使用以前的版本）。esp32模块增加了对非易失性存储的基本支持。此外，还初步支持 ESP32-S2 和 USB，并定义了一个通用的 S2板。
在mimxrt和samd移植上，USB-CDC-TX处理已修复，因此现在可以可靠地工作。
RP2移植启用了更多的Python核心特性，同时还启用了ubinascii.crc32()、uos.VfsFat和machine.Signal类，以及uerrno模块。uos.urandom() 已添加，并且machine.freq() 现在可以更改CPU时钟频率。machine.UART 类现在支持timeout/timeout_char、反转的TX/RX信号和可配置缓冲区大小的TX/RX。对于PIO，StateMachine添加了restart(), rx_fifo() 和 tx_fifo()助手函数，并支持fifo连接。现在支持用户C模块（通过CMake）和构建不同的板配置（默认仍然是PICO板）。提高了USB的可靠性。
对于stm32移植，现在有更多的板配置选项，例如USBD VID/PID和模块的fine-grained选择。UART类现在支持L0、L4、H7和WB MCU上的LPUART。WB MCU对访问BLE ACL 自由缓冲区列表的竞争条件有一个修复，解决低级BLE bug。
zephyr移植已经更新为使用 Zephyr v2.5.0，并使用 CMake 构建MicroPython。
下面是从git提交历史生成的更改的详细列表，并将其组织为多个部分。
