 -----------
+Changes in v0.7.11
+
+1) Ethash additions: printing share diff in GH (always enabled), hashrate watchdog (see --eth_hashwatch).
+2) Better debug support: --long_timestamps, --pool_debug.
+3) We've found certain motherboard/bios combinations that due to kernel and/or driver bugs have issues with the first or last gpu in rigs. If you see excessive hw errors reported on a single gpu, and switching around gpus still always generates errors in the first or last gpu, try using --eth_dag_alloc_patch.
+
+Release notes:
+- Added DAG allocation patch under linux for certain mobo/bios combinations (see --eth_dag_alloc_patch).
+- Added ethash hashrate watchdog (see --eth_hashwatch).
+- Added ethash abort mechanism for Vegas on ROCm (see --eth_direct_abort). Not useful in other contexts.
+- Added pool traffic debug (use --pool_debug).
+- Added print of share difficulty for ethash family algos. Unit is always GH.
+- Added microsec timestamp resolution in logs (use --long_timestamps).
+- Regression bug: argon2/chukwa was broken in 0.7.10, now working again.
+- Turned off compute mode checks for non-Polaris gpus.

+      --eth_hashwatch(=M,M) Defines a min/max watchdog hashrate in MH/s expected when gpus are hashing.  If a GPU falls outside
+                              of this range for too long it will be considered faulty and the watchdog will be triggered.  The
