Rigel 1.13.1

• Set GPU memory clock offset to 0 when building DAG to prevent its corruption
• Add {ts} and {algo} template parameters for log file name (see --log-file in readme for more details)

Bug fixes:

• Large amount of rejected shares when mining kawpow to Nicehash
• (RXD) Fix performance regression on Pascal GPUs introduced in version 1.11.1

Rigel 1.13.0

• Add support for mining arbitrary KawPow (-a kawpow) and Ethash (-a ethash) coins
  Old coin-specific algorithms like -a neurai are now obsolete and will eventually be removed, see below for details
• Cache DAGs when mining kawpow or ethash
  To turn off set --kawpow-cache-dag off / --ethash-cache-dag off
• (API) Add new fields:
  • zil_state, indicates whether ZIL is currently mining, possible values: waiting, mining
  • pool_hashrate

Bug fixes:

• The miner crashes if API server fails to bind

Quick kawpow/ethash configuration guide:

1. If you're mining a single coin, set --coin parameter. This is the best way to mine these algorithms as it eliminates DAG rebuilds completely. The full list of supported coin tickers is available at https://github.com/rigelminer/rigel#supported-algorithms. If your coin is not listed, don't worry, at most the miner would only need to cache two DAGs - one for your coin and one for a dev fee coin - and there's a very good chance your GPU has enough memory for both.
2. If you're mining to a profit switching pool (Nicehash, MRR, Zergpool etc.), there isn't much you can do - the miner would still be rebuilding DAGs from time to time as the pool sends jobs with different epochs but assuming your GPUs have enough memory, automatic DAG caching will do its thing and reduce the number of required rebuilds to a minimum.
3. Old coin-specific algorithms are obsolete and will be removed in one of the future releases, but for now they are mapped as follows:

Old algorithm	Equivalent
-a aipg	-a kawpow --coin aipg
-a clore	-a kawpow --coin clore
-a neoxa	-a kawpow --coin neox
-a neurai	-a kawpow --coin xna
-a ravencoin	-a kawpow --coin rvn
-a octa	-a ethash --coin octa
-a powblocks	-a ethash --coin xpb

Rigel 1.12.2

• (PYI) Improve performance on 16xx series GPUs
• (ZIL) Display hashrate between rounds (set --zil-retain-hashrate off to disable this feature)

Bug fixes:

• (ZIL) The miner keeps connecting to the failover pool even when the primary pool is up

Rigel 1.12.1

• (PYI) Significant hashrate increase on 16xx series GPUs
• (ZIL) Calculate pool hashrate accounting for Zilliqa not being mined continuously - now it reflects what the pool dashboard would show
• Add --no-pool-url option to hide the pool URL from the log and display the algorithm name instead

Rigel 1.12.0

• (AIPG) Add AI Power Grid mining support (-a aipg), dev fee 1%

Bug fixes:

• GPU memory temperatures are not displayed on 545+ drivers, and on some cards with HBM2 memory

Rigel 1.11.1

• (RXD) Minor hashrate/efficiency improvements
• Add RTH+PYI, ERG+PYI, CFX+PYI, +ZIL mining support, see bat/sh scripts

Bug fixes:

• (PYI, KLS) Extranonce parsing error when mining to stratum bridges
• The miner accepts multiple overclock arguments for the same GPU / clock type instead of displaying an error

Rigel 1.11.0

• (PYI) Add pyrinhash algorithm (dev fee 1%, see pyi bat/sh script)

Rigel 1.10.1

• Add support for Volta architecture (Titan V)
• Add CFX+KLS and CFX+KLS+ZIL mining support (see dual-cfx-kls bat/sh script)

Bug fixes:

• (KLS) Unexpected EOF error when mining to Mining Rig Rentals

Rigel 1.10.0

• (KLS) Add karlsenhash algorithm (dev fee 1%), including
  • RTH+KLS, ERG+KLS, ETC+KLS, +ZIL, see bat/sh scripts
• (KAS) Remove kheavyhash algorithm

Rigel 1.9.2

• Add PowBlocks mining support (-a powblocks)
• Remove flora algorithm

Bug fixes:

• (Windows 7) TUI is broken
