NEW VERSION 4.0.0, MAY 26 2014

Human readable changelog:

• Various options (specifically, --temp-cutoff, --temp-target, and the various --<driver>-options) have been migrated to the --set-device interface.
• Automatic hotplug support for Linux and Windows.
• TUI: Redesigned pool information line to include share difficulties in multipool modes and timestamp of the last explicit work update (which are no longer logged).
• Forbid cross-domain server redirection by default, unless pool URI has #redirect in it.
• Stratum: Unauthenticated TLS support.
• Stratum: Improve support for stratum-compliant scrypt servers, while still cleanly handling the expectations of many broken servers.
• bifury: Support for OneStringMiner and Hex*Fury (see README.ASIC for notes about boards with buggy firmware).
• bitfury: Detect gen2 chips and report hashrate correctly.
• bfx: New driver for BFx2 Bitfury USB stick miners.
• bitforce: Support for Monarch 28nm cards, including PCI-Express support on Linux (see README.ASIC for setup instructions).
• drillbit: Add support for protocol version 4 devices.
• dualminer: New driver, supporting both SHA256d and scrypt ASIC mining.
• gridseed: New driver, supporting only scrypt ASIC mining.
• hashbusteravalon: New driver for Avalon2-based HashBuster devices, such as the HashBuster Alpha.
• hashfast: Display of temperature and voltage, as well as setting clock frequency at startup.
• icarus & cairnsmore: Since Block Erupters are far more popular, and less unprofitable, the erupter driver is now preferred over icarus and cairnsmore drivers. This means you must change -S all to -S icarus:all or -S cairnsmore:all.
• knc: Added a use_dcdc setting that can be used on Nov batch units to avoid triggering DCDC problems (--set knc:use_dcdc=no).
• nanofury: Support for new, multi-chip NF2 and NF6 units.
• RPC: cpu* and gpu* commands have all been deprecated; CPUs and GPUs are now accessible using pga* and proc* commands just like everything else.
• Stratum proxy: Support for GBT upstream pools, as well as scrypt algorithm.
• getwork proxy: Support for scrypt and included in Win64 binaries.
• opencl: Major updating of code to use set-device interfaces.
• opencl: Support for loading kernels by filename, provided they use a known interface. Loading most scrypt kernel should just work, and most SHA2 kernels can be enabled by adding a single comment to the CL source.
• opencl: Support for new "xintensity" unit by using --set-device OCL:intensity=x5 (for example).
• opencl: Raise max scrypt GPU intensity to 31, and enabled driver by default for scrypt.
• opencl: Add some optimised scrypt kernels by zuikkis and psw.
• scrypt: Fixed nonce-based (third) hashrate, and display sub-one share difficulties.
• Default log interval (and first hashrate rolling average) increased from 5 seconds to 20 seconds to make it more useful.
• Benchmark mode refactored to work for both SHA256d and scrypt, and with the third hashrate.
• Many uncommon options (including CPU and GPU mining related ones) have had their "shorthand" forms deprecated. A future release will remove (and perhaps redefine) these shorthands entirely.
• Bundled a start-bfgminer.sh shell script for *nix which will start/restart BFGMiner in a screen session, and can safely be used in init/cron tasks.

Full changelog:

• Update openwrt Makefile for xz source
• Update libblkmaker to 0.4.0
• Workaround Homebrew-induced segfault during device scan

• Bugfix: Avoid using an enum type to hold a bitfield
• ruby extension is "rb" not "py"
• README.RPC: Document api-example.rb

• Use cURL return code to check if cURL sockets hit CURLE_AGAIN
• Abstract pool_recently_got_work into a dedicated function
• AUTHORS: Dmitry Smirnov contributes BFGMiner packaging to Debian

• bitfury: Eventually (after 30 seconds) give up trying to detect chip generation and just assume gen1
• bitfury: Use other nonces for gen1 detection so one bad core can't break it
• Bugfix: bitfury: Account for necessary nonce fudging during chipgen detection
• gridseed: Switch from the Queued miner loop to the Scanhash miner loop Improves performance on Raspberry Pi Fixes inaccurate hashrate estimates Fixes bug overwriting work inadvertently
• If the current pool lacks its own block change detection, keep the pool used for that connected
• pool_active_lp_pool function to complement select_longpoll_pool

Congrats Luke! Testing ASAP.

[freddyfarnsworth]

Congratulations ! Lots of new work

Will test here. W XP laptop and three hubs.

[norgan]

nice work! will test with network and usb devices I have. any more info on the new device options, does auto overclock work with the antminers?

[ManeBjorn]

Great job Luke.
I updated the article with the official release.

http://www.cryptocoinsnews.com/news/bfgminer-4-0-officially-released-multiminer-3-0-officially-released-tandem/2014/05/24

Luke Jr has officially released BFGMiner 4.0 into the wild with a ton of enhancements and features. Along with it a key member of the development team Nate Woolls released MultiMiner 3.0 to go along with it. Update: BFGMiner is live. 5/26/14  Quick Note: Slight Delay on BFGMiner.  It will be posted soon. :-) Notable in the BFGMiner release is the support for many new miners that have come on the scene. Some you will recognize from my reviews like the OneString Miner, HexFury and Gridseed Blade reviews. The official support makes BFGMiner even more hardware friendly. There is even support for the hard to find DrillBit miners.  Notable is the support for the extremely late Butterfly Labs Monarch miner which is looking more and more like a waste of Bitcoin that buys Josh of BFL a house and two cars. More support for the multi-chip Nano Fury miners and so much more. The new hardware support is great because it allows quick integration into your existing BFGMiner controlled ecosystems without messing around.

Thanks again for the hard work and allowing me to spread the word about it.

[Anonymailer]

Awesome, thanks luke! I've updated MacMiner from 3.99 to 4.

[nwoolls]

Awesome, thanks luke! I've updated MacMiner from 3.99 to 4.

Ah - just the person I was looking for! Time to put you on the spot 

As a fellow Mac dev and someone familiar with BFGMiner, if you could take a peak at this and see if there's anything you can crack that would be super:

https://github.com/luke-jr/bfgminer/commit/1c4821cbe814845c0c72530f3fba3b9040647648

This put Luke and I back a couple days on releasing 4.0 and, in the end, we still had to go with a work-around rather than finding a proper solution. It would be great to get someone else with the required resources and system taking a look.

[Taugeran]

Thanks for the day early birthday present Luke ^_^

Now 20

• A few device drivers for scrypt:
  • DualMiner ASIC-based USB miner
  • OpenCL GPUs, such as AMD Radeons
  • CPU (not enabled by default nor included in Windows build)
  • Coming soon:
    • 5-chip Gridseed mining orb
    • any other device provided for development (PM me)

We do want to credit and thank both DualMiner.com and LIGHTNINGASIC Co., LTD for sponsoring the development of these drivers. This is not an endorsement of their hardware or services beyond their commitment to Open Source mining software to power their ASIC hardware. Thank you!

multiminer is actually passing the following:

-S antminer:\\.\com3 -d antminer@\\.\com3 etc if I strip all extra switches out it still shows the error. is it a multiminer issue?

[nwoolls]

multiminer is actually passing the following:

-S antminer:\\.\com3 -d antminer@\\.\com3 etc if I strip all extra switches out it still shows the error. is it a multiminer issue?

These are standard arguments for BFGMiner (plus I mine with AntMiners using MultiMiner) so it's not MultiMiner issue per se. MultiMiner does save your devices, and maybe the device COM port has changed? Just a theory. Try stopping mining, and then right-click and Scan Hardware so that the paths are all updated before starting mining again.

hey Nate, yeah I tried that and confirmed the comm port numbers from device manager. It's a funny one. just don't know if it's a bfgminer thing or a mm thing. right now I have a delay when starting but it finally gets going.

same thing the other message came back " serial "0000098681", but mcp2210 lowlevel driver failed to open it

Are there two separate issues here then?

Can you bisect each of them individually?

• Open http://luke.dashjr.org/tmp/code/webisect/webisect.php
• Enter a unique unlikely-to-be-guessed-by-someone-else session identifier
• For Working commit, put bfgminer-3.10.0 (or whatever the last version you were using was)
• For Broken commit, put bfgminer-4.0.0
• Follow instructions to test each custom build for the single bug you're investigating

Thanks

Hi Luke,

 serial "0000098681", but mcp2210 lowlevel driver failed to open it

is the main error. i'll look into what you suggested when I'm back in my office tomorrow.

EDIT: I just tried that and it bombed out:
