IAR Embedded Workbench for ARM

Version 5.10 is the main release and prefered installation. It will give you the latest features, program corrections and device support. If you're upgrading from V4.xx to v5.xx, then V5.10 requires some migration changes to your C, ASM and linker config file. It is important that you review the migration path document before using it on your v4.xx code.

Version 5.10 does however lack support for for Cortex-M3 and VFP (but is supported in 4.42A). Version 5.x support for Cortex-M3 and VFP will be available October 2007 (in version 5.11).
