This is the first announcement on upcoming changes to the supported Linaro GCC versions.
GCC 4.7 is expected out in the next two weeks. We plan to switch to 4.7 for the Linaro GCC 2012.04 release and, as part of that, will put Linaro GCC 4.6 into maintenance and retire Linaro GCC 4.5. While in maintenance we will continue to update, fix bugs, and do releases on 4.6. No further changes or releases will be made to 4.5. All historical releases and branches will stay available.
For more informatio, please see the flyer at: https://wiki.linaro.org/WorkingGroups/ToolChain/Flyer
especially the section on Lifecycle: https://wiki.linaro.org/WorkingGroups/ToolChain/Flyer#Lifecycle
The formal change notes will be sent after the 2012.04 release.
