-----------
Changes in v0.7.18

1) Support for the ETC fork added. Run with "-a etchash" for easiest support, see "--eth_variant_mode" in the help for more info.

2) ETH+ZIL miners: add "--eth_dag_cache=0" to use a second dag cache and prebuild epoch 0 immediately at miner start.

3) Ethash miners relying on ramp-up and stagger for stability: the default mode of these tweaks has been changed to off. They now need to be enabled with --eth_ramp_up and --eth_stagger. While helping a number of rigs, these tweaks caused increased instability of others, making the choice of a good default mode difficult.

Release notes:
- Added etchash support (see algo etchash and --eth_variant_mode).
- Added dag cache support, mostly intended for eth+zil mining (see --eth_dag_cache).
- Fixed hex char parsing in enable/disable submenu, can now work with >= 10 gpus.
- Changed the default for ethash ramp-up and staggering to false (see --eth_ramp_up and --eth_stagger).
- Added check for broken win setups with duplicated opencl platforms and/or devices.

Team Red Miner version 0.7.17
Team Red Miner version 0.7.18
Usage: teamredminer [OPTIONS]
Options:
-a, --algo=ALGORITHM Selects the mining algorithm. Currently available:
ethash (eth, etc, etp, others)
etchash (alias for -a ethash --eth_variant_mode=etchash)
kawpow (ravencoin)
lyra2z
phi2 (lux, argoneum)

applied to each GPU. For example: --eth_config=A,B750,,A288
Any gpu that does not have a specific config in the list will use the first

--eth_variant_mode=X This argument controls activation of the ethash changes for ETC from epoch 390 as described
in ecip-1099. The following modes are available:
pool - Default mode. Only activates if the pool sends an algo flag containing etchash.
Once this flag is seen, all pool jobs will be assumed to be etchash unless another.
algo flag containing ethash is received.
etchash - Etchash mode. Epoch >= 390 will be assumed to be etchash, lower epochs ethash. Pool
algo flags are not used.
deduce - Ignore pool algo flags and only apply a heuristics based on the current system time
and known heights and times for ETC and ETH. This mode should work as a generic
approach when ETH reaches epoch 390 in Jan 2021. The system clock needs to be correct.
It should also handle any profit switching setups that switch freely between ethash and
etchash jobs by proxying underlying pools.
auto - As long as the pool hasn't passed an algo flag, use deduce mode. When an algo flag
is seen, switch to pool mode.
ethash - Forced ethash mode. Never apply ecip-1099.
force_etc - Forced etchash mode. Always apply ecip-1099 rules. Use for ETC testnet mining.
--eth_aggr_mode Enables automatic use of the 'B' mode for all Polaris 8GB cards, unless they have a
different config provided by the --eth_config argument. This is the same thing as
manually setting all Polaris 8GB gpus in the rig to 'B' mode using --eth_config.

1 means minimal slowdown, 9 means max. Default value: 4 for a slight slowdown.
--eth_no_stagger Disables the staggering of gpus when building a new DAG. The default behavior is to stagger
GPUs so they don't all enter the DAG build process at exactly the same time.
--eth_no_ramp_up Disables the ramping up of intensity for each gpu.
--eth_stagger Enables staggering of gpus when building a new DAG. This is more lean on PSUs that don't like
going from 0-100% load on all gpus at the same time.
--eth_no_stagger Disables --eth_stagger. Already the default behavior from 0.7.18. Argument kept for backwards

--eth_ramp_up Adds ramping up the intensity on all gpus after a DAG build, gpu disable/enable or network outage.
Can help rigs with crashes right between the DAG build and starting mining.

--eth_direct_abort Uses a different mechanism to abort ongoing gpu jobs. Recommended for Vegas in ROCm environments
to minimize stale shares. Will apply to Vega and Polaris gpus in the rig only.

to handle gpu resets that result in huge fake hashrates but no minimum check.
--eth_dag_cache(=EPOCH) Enables saving eth DAGs from jobs with different epochs to prevent having to rebuild them in the
future if jobs with the old epochs are received again. At most one DAG will be saved if GPU memory
space allows. This is useful for switching pools such as eth+zil mining. If you want to prebuild a
certain epoch immediately at startup, add the optional value. Eth+zil switching miners should use
--eth_dag_cache=0. Only ethash (and not etchash) epochs can be prebuilt at this time.
--eth_dag_cache_resv=MEM Sets the amount of GPU memory the miner will attempt to leave unused when running with DAG caching
enabled (see --eth_dag_cache). The argument MEM is the amount of memory to leave unused in
mebibytes. The default value is 256.
