Usage
T-Rex supports command line arguments similar to that of ccminer:
x16r:
Code:
t-rex -a x16r -o stratum+tcp://eu.minermore.com:4501 -u <wallet> -p x
MTP:
Code:
t-rex -a mtp -o stratum+tcp://xzc.2miners.com:8080 -u <wallet> -p x

To get the full list of supported options run:
Code:
t-rex -h


Dev fee
Dev fee is set to 1%. When the miner starts and stops mining dev fee it reports it to the console output.

New algo: geek (GeekCash coin)
Performance improvements (1-3%) of x16-like algorithms for GTX/RTX cards.
Added watchdog. Replace "t-rex.exe" with "watchdog.exe" in your bat file in order to use it.
Watchdog lets you update T-Rex using the monitoring web page or perform auto-updates if launched with "--autoupdate" parameter, and also restarts the miner if it hangs for any reason.
Default value for "-N" paramater increased from 30 to 60 seconds.
Added "shares per minute" stats read-out.

Minor performance improvements for skunk and x16 family of algorithms for Pascal and Turing cards

Bug fixes:
Crashes 20 sec after dev fee session when using -r 0
Temporary backed out "clean job" feature that was causing rejects on some pools e.g. beepool and bitpoolmining

0.7.3
Improve skunk, phi, polytimos; small improvements for x16r/s etc on some configurations.
Performance improvements for Turing GPUs (20xx series)
Add functionality to return to the main pool after mining on failover ones (see --back-to-main-pool-sec launch parameter)
Handle client.reconnect stratum messages (used by MiningRigRentals)
Handle clean jobs stratum flag correctly (resulting in fewer stale jobs) - this feature is supported by coinblockers.com
Add file handler to API. Allows to create custom files in miner directory via API.
Add functionality to keep your failover pools separately in a config file. May be helpful if you need to load pools from file. (t-rex -c pools.json -a x16r <your parameters>)

Bug fixes
Remove assert on NULL rpath in Linux.
Fix average hashrate reporting when using large -N values.

0.7.2
Added algo: x22i
Note: if the miner crashes on x22i, decrease your overclock, the algorithm is quite "unstable"


0.7.1
Added algos: sha256t, timetravel
Replace "--exit-on-fail-shares" parameter with "--reconnect-on-fail-shares"
New/changed arguments:
--temperature-start: When a GPU cools down to this temperature the miner starts using it again
--exit-on-fail-shares: Now replaced with --reconnect-on-fail-shares
-r (--retries): if set to 0, miner exits immediately upon the first network failure
--cpu-priority: Set process priority (default: 2) 0 idle, 2 normal to 5 highest

Allow C-style comments in config files (see config_example). Can be used to disable failover pools temporarily etc.
A few cosmetic changes.

API:
Multiple http://localhost:4067/trex page enhancements, it now displays all the info you see in the console, including hashrate/power consumption on the graphs with zoom option. (click on left mouse button and drag) Don't need to use console anymore use your browser instead!
New API handler "config".
Some miner parameters can now be changed and saved on the fly.
Please see the help file for additional details.

Bug fixes:
"bad weak ptr" error
Share rejects were not displayed (Suprnova, Aikapool, possibly some others)
Command line arguments did not always override config file


0.7.0
Speed improvements: there's ~1% improvement in x16 family of algorithms on some configurations.
Add support for Volta (Titan V) and Turing (20xx) cards - not optimised yet. Download CUDA 10 version to run on 20xx cards.
New arguments:
--temperature-limit: When a GPU reaches the temperature limit (in Celsius) the miner stops using it and keeps mining with the rest of GPUs
--exit-on-fail-shares: Forces miner to immediately exit on N successively rejected shares (default: 10)
Command line arguments now take precedence over config files. If an argument is set in both places, the value from cmd line overrides the config one.
New HTTP API handler that allows you to control the miner via a web browser on the fly. By default is accessible at http://localhost:4067/trex. Functionality is limited but will be extended in future releases if there's demand. We're looking forward to getting your feedback.

Bug fixes:
Stability fixes, especially on x16r/s and bitcore
CUDA version reported by the miner is now the version that the miner has been built against rather than the one installed on user's machine
Redirection of console output to stdout on Windows with no buffering in place.

Cosmetic changes:
Add miner efficiency (Hashes per Watt) to console output and API
Print "Submitting found block!" message when a block is found and return this info in API


0.6.10
Speed improvements: x16r/s, x17, c11, bitcore, bcd, sonoa - 1-2%
Add functionality for setting failover pools in cmd line by specifying -o, -u and -p arguments multiple times.
New cmd line arguments:
--gpu-report-interval: controls how often GPU report stats are displayed (by default every 5th share).
--no-color: disable coloured output
--time-limit: maximum time to mine before exiting the program.
--quiet: disable GPU stats output
Add ability to change averaging hashrate window, enable protocol dump mode, and change GPU report interval via API or web browser on the fly (without stopping the miner) - see the help file.

Bug fixes:
Hung/freeze issues
Invalid shares on x16r
Long log path issue on Linux
"extranonce subscribe timed out" on suprnova pools

Cosmetic changes:
Showing configured pools upon start up
Displaying colour representation of hashorders for x16r/s

To disable API altogether set --api-bind-http / --api-bind-telnet to 0.
HTTP API: new control command "shutdown" to quit the miner (read help file for details)

0.6.5
New algo: bcd
Speed improvements:
x16r/s, bitcore, renesis, hmq1725 - 2-3%

Slight improvements (few %) of all algorithms except lyra2z.
Added extra shares submit functionality. Reduced the number of rejects on pool side (both resulting in increased poolside hashrate).
Fix for multiple scenarious where the miner used to freeze.
Fix "doesn't validate on CPU" errors for phi/renesis algos.
Display pool latency when submitting shares.
Support decimal intensity values (e.g. 21.3)
Highlight accepted/rejected shares using different colours (Windows version)
Display GPU full name/temperature/power consumption/fan details.
New command line option -P (stratum protocol dump).
-N option now uses seconds rather than samples as a unit of measurement. E.g. -N 30 means a sliding window of 30 seconds is used to calculate average hashrate.
Added support for Compute Capability 5.0 cards (e.g. 750, 750ti).

HTTP API:
Added GPU full name/temperature/power consumption/fan details.
Added current pool details (name, difficulty etc)
