End of active development for STM32F3 based flight controllers

For a while now, development of Betaflight for flight controllers based on the STM32F3 chip has been hampered by a severe limitation that this chip has: Unlike the STM32F4 and STM32F7 models, the STM32F3 versions that are used on flight controllers have only a very limited amount of flash space available to fit the firmware into. This has meant that, starting from around version 3.3, the majority of the new features that were developed for Betaflight could not be added to STM32F3 based boards. Even worse, due to improvement in basic features, other more and more of the less commonly used features had to be removed from these flight controllers, and a number of them are at a point where they only support the bare minimum of functionality required to make them fly.

This means that, even if we kept supporting STM32F3 based boards in future releases, there would only be little advantage in this, as there simply is no space left on STM32F3 to add any of the new features that these releases will contain.

For this reason, and because the effort required to remove features from STM32F3 based flight controllers on a weekly basis is cutting into the time that we have to actually develop new features, we have decided to drop support for STM32F3 based flight controllers after the last release of 4.0.

This does not mean that it won't be possible to use these flight controllers after this point in time - they will still work fine when used with the last release of 4.0, just as there are thousands of users who are still enjoying their STM32F1 based flight controllers with Betaflight 3.2.5. We will also strive to keep these versions supported in new releases of configurator, so that users still using these flight controllers will be able to configure them with the same configurator that they use to configure their STM32F4 and STM32F7 based boards.

STM32F3飞控的固件系统将不再有新版本

一段时间以来，基于STM32F3芯片的飞控betaflight的开发受到了该芯片的严重限制：与STM32F4和STM32F7型号不同，用于飞控的STM32F3版本只有非常有限的闪存空间可用于安装固件。这意味着，从3.3版开始，为betaflight开发的大多数新功能不能添加到基于STM32F3的板上。更糟糕的是，由于基本功能的改进，越来越多不常用的其他功能必须从这些飞控中删除，其中一些功能仅支持使其飞行所需的最低限度的功能。

这意味着，即使我们在将来的版本中继续支持基于stm32f3的板，这也没有什么优势，因为stm32f3上根本没有空间添加这些版本将包含的任何新功能。

因此，由于每周从基于STM32F3的飞控中删除功能所需的努力缩短了我们实际开发新功能所需的时间，我们决定在4.0的最后一个版本发布后不再支持基于STM32F3的飞控。

这并不意味着在这个时间点之后就不可能使用这些飞控——当与4.0版本以前的固件一起使用时，它们仍然可以很好地工作，就像成千上万的用户仍然在享受他们的基于STM32F1的飞控与BetaFlight 3.2.5一样。我们还将努力在新版本的配置器中保持这些版本的支持，以便仍然使用这些飞控的用户能够使用与配置基于STM32F4和STM32F7的板相同的配置器来配置它们。
