+ Introduced API function xTaskResumeFromISR(). Same functionality as xTaskResume(), but can be called from within an interrupt service routine. + Optimised vListInsert() in the case when the wake time is the maximum tick count value. + Bug fix: The 'value' of the event list item is updated when the priority of a task is changed. Previously only the priority of the TCB itself was changed. + vTaskPrioritySet() and vTaskResume() no longer use the event list item. This has not been necessary since V4.0.1 when the xMissedYield handling was added. + Lowered the PCLK setting on the ARM9 STR9 demo from 96MHz to 48MHz. + When ending the scheduler - do not try to attempt a context switch when deleting the current task. + SAM7X EMAC drivers: Corrected the Rx frame length mask when obtaining the length from the rx descriptor.
