The wiki is versioned (through different URLs), and its versions correspond to major developments in the Yocto-based OpenSTLinux flagship ecosystem, of which the BSP serves as the basis for the other Linux-based ecosystems.

A release flow for the Yocto-based OpenSTLinux ecosystem designates all the releases of the Yocto-based OpenSTLinux ecosystem which are based on the same versions of the major software components such as the Linux^® kernel (see details in the table).
Each vx release flow groups together all the vx.y.z releases of the Yocto-based OpenSTLinux ecosystem, and has its own wiki.

Thus, the wiki versioning is driven by the vx release flow (implied meaning, of the Yocto-based OpenSTLinux ecosystem), but any wiki contains also releases for other ecosystems such as the bare metal - RTOS ecosystem or the Android-based OpenSTDroid ecosystem.
The most recent flow is associated with the latest wiki also known as main/flagship wiki (whose URL is "https://wiki.st.com/stm32mpu"), while the previous flows are associated with archived wikis (whose URLs are "https://wiki.st.com/stm32mpu-ecosystem-vx").

The main wiki is for the v6 flow (v6.y.z releases of the Yocto-based OpenSTLinux ecosystem): if you discover the STM32 Arm^® Cortex^®-based MPUs, it is highly recommended to continue browsing this wiki that contains the latest major ecosystem releases for STM32 Arm^® Cortex^® MPUs .

However, if you need information about any previous release flows, browse the associated wiki thanks to the below table:
