This is the announcement thread for lolMiner 1.11  a multi algorithm Ethash / Equihash / Beam & Grin miner with focus on AMD GPUs (OpenCL based).
Note it will run on most Nvidia GPUs, too but the speed and stability may vary.

Changelog

Version 1.12

• Added support for ETCHash (Ethereum Classic dag size reduction planned for end November). Use --algo ETCHASH to activate it. (See note below).
• Reworked Ethash codes for late epochs on Windows. See  4G_Windows_Readme.txt for configuring it.
• Slightly improved Ethash efficiency for GCN 3 (R9 Fury, 470 - 590) & Navi cards
• Added experimental support for Ethash on Nvidia GPUs (See note below)
• Added new parameter: --4g-alloc-size to define the memory allowed for Ethash on 4G cards. Maxing out will give more epochs of mining & better Zombie mode performance, lower values may improve compatibility. Suggested values: Linux: 4076 Windows 4008 - 4024
• Added new parameter: --worker to set the worker in ETHPROXY stratum mode (improves pool compatibility)
• Overall new Ethash host size back end - hopefully improving stability of mining
• Fixed bug: Zombie mode generates defect shares in Windows
• Fixed bug: Logs were not written when "LOG" : 1 was set in json style config file

Version 1.11

• Added experimental ZOMBIE mode for 4G AMD GPUs (Fiji & Polaris). This will allow continue mining Ethash above the 4G DAG size limit with some time memory trade of. This allows efficient ETH mining until ~February in Linux and end of this year in Windows (a),(c).
• Complete rework of Ethash memory allocation strategies (see below)
• Added bestshare display & api output for BeamHashIII
• Fixed BeamHashIII for R9 380 8G cards (they now use the working 4G code)

New allocation strategies:
For 8G cards:
-> The ZIL cache is now stable and can be safely enabled on all drivers
-> Temporarily fixed allocation issues on 19.x drivers in Linux (b)
-> 8G cards will now allocate up to 5 epochs ahead, so they need to go through this critical phase less often

For 4G cards:
-> Windows: added experimental mem allocation pattern that should allow reaching epoch 375 or 376 at full speed ( * ). It is default on in Windows, you can turn it off with "--win4galloc 0"

(a) The new memory allocation pattern and the Zombie mode are highly experimental in Windows and can occasionally produce defect shares. This will be fixed in next version.
(b) The fix might stop end working on epoch 384. If you see the miner struggling to start up when coming close to that epoch, then consider upgrading your driver or installing a different Linux kernel. The problem only occurs with some amdgpu-pro drivers with version number 19.x (20.x are fine !) and some Linux kernel versions.
(c) On higher epochs the Zombie mode may need a bit more power then for working epochs. If you see crashed loosen your OC / UV settings slightly until it is stable again.


Version 1.09

• Added support of Vega GPUs on 18.30 and 18.40 drivers on Ethash and BeamHash III
• Fixed bug: Miner crashes on startup when Ethash coin different to ETH / ETC is mined
• Fixed bug: Stratum module may crash on epoch change or not amend epoch change
• Fixed bug: DAG epoch less then 200 should work now (instead of crash)
• Fixed bug: short statistics show very high hash rate after temporary connection loss. Note: on startup first 30 seconds will show lower hash rate now since it involves DAG generation.
• Fixed bug / new feature: stratum does no longer crash when EthereumStratum/1.0.0 login request is responded in Ethproxy format. Instead stratum module now tries to change the mode to fit the pools format.

Version 1.08

• Added support for Ethash on AMD GPUs (R9 380 and newer) at 0.7% fee. Use --algo ETHASH to mine it.
• For Ethash in Linux all 4G cards are supported up to epoch ~380 to 382 (most often: 381). 6G and higher cards are ready to run past passing the 4G barrier - 8G cards are verified to work up to epoch 700. Windows use of 4G cards might work, but can not be guarantied. To test it, use --keepfree parameter.
• Added support for BeamHash III on 4G Tonga (R9 280(X) ) GPUs
• New parameter (all algorithms): Use --keepfree (default on Linux 5, Windows 150) to set the number of MBytes the miner should reserve on each GPU for the operation system. On Ethash this will affect the maximum epoch the miner tries to start, on other algorithms the kernel the miner will run (in case a lower memory kernel is available).
• New ethash specific parameter: Use --benchepoch among with --benchmark ETHASH to run the benchmark mode for a fixed epoch height (default: 350)
• New ethash specific parameter: Use --ethstratum to set the stratum mode for ethash. Currently available options are ETHV1 (default) and ETHPROXY
• New ethash specific parameter: Use --dagdelay to put a delay in seconds between allocation of DAG for the single GPUs. May help especially in Windows to get a rig with low system memory and small page file running.
• Fixed bug: watchdog toggle was inactive although it should be active.

Version 1.07

• Added support for mining Cuckoo 29 (Aeternity, use -a C29AE) on 6G+ cards
  
• Added support for mining Cuckaro 29-48 (Planned Italocoin fork, use -a C29-48 ) on 6G+ cards
  Minor cosmetic fixes
