Streaming trace for improved code coverage and profiling featuresThe code coverage and profiling windows in C-SPY can now be feed with streaming trace data when using the IAR I-jet Trace probes. This means that both code coverage and profiling data can be collected during infinite test runs. See IAR Embedded Workbench C-SPY Debugging Guide for more information. Extended multicore supportThe multicore support has been extended to support any number of asymmetrical cores. For example, it is now possible to debug and control a device with one A9, one M7, and two M4 cores, all synchronized by the Arm Coresight CTI mechanism under debugger control.

Performance Monitoring windowThe Performance Monitoring window is a viewer for counting events or CPU clock cycles through the Performance Monitoring Unit (PMU) available on Cortex A and Cortex R processors. This feature is only available when using an IAR I-jet probe. Live update is available on all recent Cortex-A cores.
See IAR Embedded Workbench C-SPY Debugging Guide for more information. Indicator for sleep modeA new window in the C-SPY debugger shows if the processor is sleeping or not. See IAR Embedded Workbench C-SPY Debugging Guide for more information. C-SPY plugin for the UNISON RTOSThe REMEDY RTOS Viewer from RoweBots is now included as a C-SPY plugin. It provides updated information on operating system objects and system state information for the UNISON RTOS. Support for new devicesThis version adds support for new devices from Analog Devices, STMicroelectronics and Toshiba.
Support for the C11 language standardThe compiler and libraries add support for the latest C language standard ISO/IEC 9899:2011.Note: the new C library binary object interface is incompatible with earlier versions of the product. Support for the C14 language standardThe compiler and libraries now support the latest C standard ISO/IEC.Note: the new C library binary object interface is incompatible with earlier versions of the product. Unicode supportThe Unicode standard for consistent encoding, representation, and handling of text is now supported.
This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code. IDE performance improvementsGeneral improvements of the IDE startup time and overall performance. Stack protectionThe IAR C/C compiler for RL78 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.
C-STAT MISRA CThe MISRA C 2004 package in C-STAT has been updated with about 20 new checks, some of which are enabled by default. Updated device supportSFR header files, linker configuration files, and device description files have been added for the latest Renesas devices. Updated IDE look and feelThe IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials. Enhanced Registers and Symbols windows in C-SPYThe C-SPY Symbols and Registers windows have been re-designed with new features.
The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.

Parallel buildIAR Embedded Workbench can now build projects using multiple parallel processes. This can improve build performance significantly on multi-core or multiple processor computers. C-SPY debugger improvements. There is now a search box in the C-SPY Register window for finding a specific register. It is now possible to sort the entries in the C-SPY Statics window by clicking on the respective column header.
If a selection is made in the C-SPY Memory window, then the Find and Replace context menu commands now operate just on this selection. The new C-SPY macro MessageBoxYesNo displays a Yes/Cancel dialog box and returns the user input. Typically, this can be useful for creating macros that require user interaction.Building all configurations with iarbuildBy specifying a wildcard character (.) as the configuration name, it is now possible to clean/build/make all configurations defined in the project file by calling iarbuild.exe only once. Control of optimized DLIB library functionsSome of the DLIB libraries delivered with the product now contain optimized variants, such as a small integer division routine for Cortex-M0, or a fast strcpy implementation for cores that support the Thumb-2 ISA. The compiler and linker will automatically select the variant that matches the optimization goal. It is possible to override this selection by using the option -useoptimizedvariants. See user guide corrections for more information.
CMSIS-DAP v2The debugger now supports the latest CMSIS-DAP standard with WinUSB transfer mode resulting in faster debug experiences when using CMSIS-DAP v2 compliant boards. Support for new devicesSupport for new devices from Ambiq, Cypress, Microchip, NXP, Qorvo. Updated IDE look and feelThe IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.

Unicode supportThe Unicode standard for consistent encoding, representation, and handling of text is now supported. This means that you can use Unicode characters (alphabetic, numeric, symbols, emoji, etc) in the source code. Stack usage analysisWith stack usage analysis enabled, a stack usage section will be added to the linker map file with listings of the maximum stack depth for each call graph root. The analysis process can be customized to take into account such constructs as calls via function pointers and recursion. The output can optionally be generated in XML format for post-processing activities.
Stack protectionThe IAR C/C compiler for RH850 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection. Renesas Smart Configurator includedRenesas Smart Configurator is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with settings.
