This service pack includes the following:

• ST-LINK/V3
  Support has been added for STMicroelectronics debug probe ST-LINK/V3.

• Corrected problems
  See the release notes for further details.

• Support for new devices:
  STM32F071C8, STM32F723E-DISCO, STM32F730I8, STM32F730R8, STM32F730V8, STM32F730Z8, STM32F750N8, STM32F750V8, STM32F750Z8, STM32H750IB, STM32H750VB, STM32H750XB, STM32H743I-EVAL, STM32H753ZI

Highlights

• Improved multicore support
  The multicore implementation has been redesigned. It is now easier to setup and configure multicore debug sessions. The debugger can now more easily cope with startup and sleep scenarious where cores are inactive.

• Cortex-M23/M33 project setup
  You can now select secure or non-secure setup in the project options. In previous releases this had to be done using Extra Options.

• New CMSIS-Pack implementation
  The CMSIS-Pack implementation is now based on the CMSIS-Pack Eclipse plugin from Arm.

• Extended support for Arm ACLE
  The language support now adds extended support for the Arm ACLE (Arm Compiler Language Extensions).

• C++17 features
  The compiler adds support for the following C++17 features:
  - Over-aligned memory allocation.
  - Compile-time if.
  - Portable feature test macros.
  - Fold expressions for variadic templates.
  - Inline variables.
  - Initializers in if and switch statements.
  - Structured binding declarations.
  - __has_include.
