Release Notes

Purpose

STM32Cube for Agentic AI 1.1.0 delivers support for the STM32G5 and STM32H7P series. Build and DAP Debug qualification on these devices remains incomplete. This page summarizes the release and links to bundle-specific changes and upgrade procedures.

Update History

1.1.0 / November 10, 2026

This release adds STM32G5 and STM32H7P series support through updated context bundles. The installer, Build, DAP Debug, Embedded Software, STM32CubeMX2, and ST Official Documentation bundles have new reference versions. Other context versions remain unchanged.

  • ST Official Documentation 1.1.0 adds STM32G5 and STM32H7P support and improves catalog coverage, including additional board user manuals.

  • Embedded Software 1.1.0 extends example discovery, source analysis, and HAL/LL guidance to STM32G5 and STM32H7P alongside STM32C5.

  • STM32CubeMX2 1.1.0 improves STM32H7P compatibility, target and peripheral configuration, backend error recovery, and sandbox guidance.

  • Build 1.1.0 improves project-readiness checks and the CMake configure/build workflow. DAP Debug 1.1.0 improves configuration checks and tool-discovery guidance.

  • Build and DAP Debug qualification on STM32G5 and STM32H7P remains incomplete. With installer 1.1.0, the agent states the restriction and requests approval before using these contexts on the affected devices. STM32C5 is unaffected by this restriction.

  • Installer 1.1.0 selects Build, DAP Debug, Embedded Software, STM32CubeMX2, and ST Official Documentation from the 1.1.x release line during catalog-driven machine installation.

  • TRAE support is in preparation. Qualification remains in progress, and the installer continues to reject TRAE targets.

See Supported contexts and versions for the complete release-reference version table. Bundles are versioned independently of the overall toolkit release. For detailed changes, dependencies, compatibility information, and limitations, consult each bundle’s release notes as described below. Toolkit-wide limitations are listed in Known limitations.

Bundle release notes

List installed bundles and their locations with:

cube bundle list | Select-String 'cube-agentic-ai-'

Open Release_Notes.md in the reported bundle directory. On Windows, the default location is $env:LOCALAPPDATA\stm32cube\bundles\<bundle-name>\<version>\Release_Notes.md.

Use the directory reported by the command if the bundle location was customized. The notes describe that installed bundle version, not necessarily the latest version available from the registry.

Upgrade to this release

Machine installation and project deployment are separate operations. Updating bundles on the machine does not update contexts already deployed in a project.

  1. Install or upgrade the installer. For a first installation, follow the installation guide. For an existing installation, follow Update the installer.

  2. Install or update the context bundles on the machine. Continue with Update machine context bundles to obtain the latest eligible versions from the configured registry. Registry versions can advance beyond this release’s reference versions.

  3. Deploy to a new project. Follow Choose your installation to select a target and use the typical or custom deployment route.

  4. Update an existing project. Ask the AI coding agent to use the installer’s cli.project-housekeeping skill to update the project’s contexts and services while preserving its target. See STM32CubeCLI and project housekeeping for the skill’s responsibilities and Update existing project contexts for the doctor workflow and target-preserving update commands. Do not rerun first-time setup on an already deployed project.
