   registers usage now the kernel is much smaller, faster and most OS APIs
   use less RAM in stack frames (note, this is an ARM7 thumb mode specific
   optimization).
+- CHANGE: Removed the field p_tid from the Thread structure and the related
+  code, this improved the thread creation scores (~2%) and saves some RAM,
+  the trace buffer field cse_tid is now populated with a simple hash of the
+  thread pointer.
 - CHANGE: Renamed the macros chSysIRQEnter() and chSysIRQExit() in
   CH_IRQ_PROLOGUE() and CH_IRQ_EPILOGUE() in order to make very clear that
   those are not functions but inlined code. Also introduced a new macro

+*** 1.0.1 ***
+- FIX: Modified the default value for the STM32 HSI setup it was 1, it should

+- FIX: Removed an obsolete constant (P_SUSPENDED) from thread.h.
