Latest releases
We are constantly updating and refining our tools with new features, new device support and extended capabilities.
Latest version: 3.11
Improved Source Browser
The following improvements have been made to the Source Browser:
- The source browser data is generated faster as it is now running as a separate thread.
- New Source Browser Log window.
- Status indicator in the status bar.
- Enhanced feedback in case source browsing data cannot be generated.
Documentation Comments support in the editor
The editor can distinguish comments that start with /**, /*!, /// or //! as Documentation Comments. Inside a Documentation Comment, the editor can recognize keywords that begin with \ or @. If the keyword is recognized as a doxygen keyword, the Documentation Comment will appear in tooltips and parameter hints for variables and functions. See IAR Embedded Workbench IDE Project Management and Building Guide for more information.
Newer version of C-STAT
The static analysis tool C-STAT has been updated with 20 additional rules, a number of bugfixes and better reporting function.
Support new debugger
Support for STLINK-V3 has been added.
Version 3.10
Updated IDE
The IDE has a new graphical profile, enhancements to window management and docking, customizable toolbars, a revised Information Center, and new tutorials.
Extended functionality in C-STAT
The static analysis tool C-STAT has been extended with approximately 150 new checks including 90 new MISRA C:2012 checks and two new packages of checks. There are also new options to enable or disable the false positives elimination phase of the analysis and to exclude files from the analysis. C-STAT message suppression can now be controlled by directives placed in comments in the source files.
Added support for new devices
Complete device support for the following new devices: STM8S001J3, ASTWBC5V,STWBC, STWBC-EP, STWBC-MC, STWBC-WA
Updated user documentation
The IDE Project Management and Building Guide and the C-SPY Debugging Guide have been updated to reflect the product changes.

User guides and documentation
Languages and standards
The IAR C/C++ compilers offer different dialects of the C and C++ programming languages, as well as different extensions specific for embedded programming (please note that not all language standards are supported for all target implementations). The compiler can be instructed to disable extensions for strict conformance to the standards.
A wide range of industry-standard debug and image formats compatible with most popular debuggers and emulators are supported. This includes ELF/DWARF where applicable.
ISO/ANSI C/C++ Compliance
The IAR C/C++ compilers adhere to a freestanding implementation of the following C programming language standards:
- INCITS/ISO/IEC 9899:2018, known as C18 (Latest version only).
- The compiler supports all C++17 features. The C++ library supports C++14 with no C++17 additions. (Latest version only).
- ISO/IEC 14882:2015, known as C++14
- INCITS/ISO/IEC 9899:2012, known as C11
- ANSI X3.159-1989, known as C89
The ISO/ANSI C/C++ Compliance level varies between the different compilers. For complete information, please refer to the IAR C/C++ Compiler user documentation in your chosen product.
IEEE 754 standard
IAR Embedded Workbench supports the IEEE 754 standard for floating-point arithmetic.
MISRA C
MISRA C is a software development standard for the C programming language developed by MISRA, The Motor Industry Software Reliability Association. Its aims are to facilitate code safety, portability and reliability in the context of embedded systems, specifically those systems programmed in ISO C.
The first edition of the MISRA C standard, "Guidelines for the use of the C language in vehicle based software", was produced in 1998. In 2004, a second edition was produced with many substantial changes to the guidelines, including a complete renumbering of the rules. Additionally MISRA C:2012 with extended support and MISRA C++:2008 for identifying unsafe code constructs in the C++ standard have also been added to the standards.
IAR Embedded Workbench features an add-on product C-STAT so you can check compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012.
Test validation
We use the following commercial test suites to test conformance of our tools to the standards:
- Plum Hall Validation test suite for ISO/IEC C conformance
- Perennial EC++ Validation Suite for C++ conformance
- Dinkum C++ Proofer to test how our libraries conform to the C and C++ standard as well as test our STL implementation against the C++ standard.
In addition to the commercial suites, we use several in-house test suites for testing new features, regression testing, corrected errors, etc.
