IAR Embedded Workbench for ARM

Version 5.11 is the main release and prefered installation. It will give you the latest features, program corrections and device support. If you're upgrading from 4.xx to 5.xx, then 5.11 will require some migration changes to your cstartup and linker configuration files. It is important that you review the migration document before migrating your 4.xx code.

Version 5.11 does lack support for VFP (but VFP supported in 4.42A). Version 5.xx support for VFP will be available May 2008 (in version 5.20).
