OLD: BFGMiner 4.10.0: GBT+Stratum, RPC, Mac/Linux/Win64, Spondoolies SP30 - page 41.

NEW VERSION 4.0.0, MAY 26 2014

Human readable changelog:

Various options (specifically, --temp-cutoff, --temp-target, and the various ---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.

Move OpenCL kernel FAQ to README.GPU and clarify it a bit
Bugfix: Log work updates for all active pools in multipool mode
test_work_current: Cleanup
Bugfix: Differentiate pool_actively_desired from pool_actively_in_use for cnx_needed
Abstract pool_actively_in_use to handle multipool checking for multiple uses
Bugfix: antminer: Fix typo
Bugfix: renumber_cgpu: Rebuild repr strings to match new information
Bugfix: Skip final pool_active check in balancing modes (where pools switch around often)
Bugfix: Adjust quota GCD only after completely adding the pool, otherwise it will be ignored by the adjustment
Bugfix: opencl: Can only BFI_INT patch if using OpenCL binaries
SGW: Support for scrypt
README: Document VCOM low_latency flag and latency_timer sysfs attribute, which can help run more VCOM-based devices on low-end USB hosts
Add USB faqs.
Bugfix: Stratum: Wait a bit for a response before assuming the pool is hiding block contents
README: FAQ about Raspberry Pi issues
Check for when errno is set on windows as well as the windows variant for errors.
Partial: Handle interruptions to various select calls in util.c
Bugfix: configure: Only fail due to not having libusb, if the user really needs or wants libusb
Bugfix: Update help display to replace (U)tility with (I)ncome
Bugfix: Deduplicate % symbols in help display
Bugfix: Correct documentation for --shares option
cpu/scrypt: Fix last_nonce to be host endian also
Bugfix: cpu: Correct results found by scrypt algorithm
Bugfix: lowl-vcom: _get_osfhandle failure returns INVALID_HANDLE_VALUE, not NULL
Bugfix: lowl-vcom: Invalid fd checks should be for -1, not 0
Bugfix: SSM: Actually acquire and release extranonce1s
Bugfix: C reserves identifiers beginning with an underscore and uppercase letter or another underscore
Skip trying to submit shares in benchmark mode
Rework benchmark mode
Bugfix: configure: Only pull in lowl-usb for lowl-vcom if libusb is available
Bugfix: hashfast: Ensure size of hex data passed to applog is of type int
README.ASIC: Update "SGW" virtual device identifier to current "PXY"
Bugfix: klondike: Reenable hw error reporting on nonces found for unknown work
Bugfix: Expand deprecated work->subid field to int width, needed by klondike driver for tracking work
Bugfix: erupter: Sapphire detected as Emerald and Emerald not detected
configure: Remove duplicate sys/file.h check
Bugfix: httpsrv: Add missing includes for stdarg, stddef, stdio, and stdlib
hashbusterusb: Initialise send packets fully to avoid leaking uninitialised data to devices
Bugfix: Correct typo in --help ("AlgoritHms")
Bugfix: twinfury: Avoid crashing when next_work is not populated here
Bugfix: hashbusterusb: Close device after failures
Bugfix: hashbuster: Close device after failures
README: List --quota in options
README.ASIC: Update documentation for Avalon
Bugfix: Leave thr->*work alone when disabling non-minerloop_async devices
udev rules: Set flag so ModemManager ignores devices
bifury: Thermal overheat causes restart losing the clock, so resend it while temperature is over 80 C
bitforce: Explicitly assign indexes for bitforce_proto enum
Bugfix: RPC: MSG_PGASETOK does not have a string param
littlefury: Close device if there are any communication problems
littlefury: Abstract out littlefury_set_power
Bugfix: hashfast: Add missing serial_claim
Bugfix: drillbit: Add missing serial_claim
Bugfix: bifury: Add missing serial_claim
Bugfix: littlefury: Add missing serial_claim
Bugfix: Allocate all new devices completely, before trying to activate any (since the first processor may control the secondary ones)
Since scrypt miners tend to work at actual share difficulty, use that for diff1 counting
Bugfix: diff1 measurements should be increased by nonce difficulty, not share difficulty
drillbit: strtol into a long int so negative responses properly get an error
Rename *nonces variables to *_diff1 to reflect their nature better
Refactor diff1 records to properly weigh non-diff1 work
AUTHORS: Add Nico Oelgart
Fixed multiple XSS injection vectors
drillbit: Expand allowed external clock range to 0-65535
