+@quotation Compatibility Note
+Segger released many firmware versions for the many harware versions they
+produced. OpenOCD was extensively tested and intended to run on all of them,
+but some combinations were reported as incompatible. As a general
+recommendation, it is advisable to use the latest firmware version
+available for each hardware version. However the current V8 is a moving
+target, and Segger firmware versions released after the OpenOCD was
+released may not be compatible. In such cases it is recommended to
+revert to the last known functional version. For 0.5.0, this is from
+"Feb 8 2012 14:30:39", packed with 4.42c. For 0.6.0, the last known
+version is from "May 3 2012 18:36:22", packed with 4.46f.
