It’s time again to update your miners. cgminer has just released version 3.8.1 of their command line mining software. You can download the application from the following location:

http://ck.kolivas.org/apps/cgminer/

The change log is included below:

Version 3.8.1 – 11th November 2013

– Revert “Send a zero length packet at the end of every usb transfer on windows

in case libusb internally has batched them into one maxpacket sized.”

Version 3.8.0 – 10th November 2013

– api update version to 2.0 and remove GPU form API-README

-Remove now unused scrypt files.

– api.c remove all GPU/gpu references and correct code as required

– Rudimentary removal of GPU OpenCL and Scrypt features from api.c

– Reorder configure alphabetically for devices to compile and fail if no support

is selected to be compiled in.

– BaB update/format some comments

– BlackArrowBitfury early GPIO V1 driver

– Fine tune the reading of results in bitfury driver to not lose any across work

restarts or corrupt due to store results not parsed during restart.

– Send a zero length packet at the end of every usb transfer on windows in case

libusb internally has batched them into one maxpacket sized.

– Framework for ntime rolling, keep looking for OP_USB_INIT replies when other

packets received

– Configure source for a new BaB driver

– sha2 allow external access to some macros and the K array

– Fixed a math issue when reporting fan speed on the status line.

– Use the main hashlist to store work done in the bitfury driver and remove work

from the list by time, thereby fixing the duplicates at startup. Count hardware

errors for when no match occurs.

– Add a get and queue helper work function.

– Remove GPU mining code.

– Use libusb’s own zero length packet support unless we have to emulate it on

windows since only libusb knows for sure if it’s needed.

– Unlock the avalon qlock while sending tasks to not hold the lock for an

extended period.

– Sleep in avalon send task on return to the function to allow other code to

work during the sleep period.

– Send zero length packets when terminating a usb write aligned to

maxpacketsize.

– Do the driver flush in avalon code lockless since it can lead to deadlocks.

– Reset the work_restart bool after the scanwork loop in case the driver flushes

work synchronously.

– Only check for the stratum clean message if we have had a valid message.

– Get rid of the stage thread since all work can be asynchronously added now via

hash_push anyway.

– Remove the now incorrect faq entry regarding scrypt difficulty.

– Check for fatal read errors and break out of the read loop in avalon.

– Send errors are basically fatal in avalon driver so break out of the send

tasks loop.

– Make the avalon driver return -1 for hash count when usb fails, allowing the

main loop code to send it the shutdown flag.

– Break out of the hash work loops when a failure is detected instead of

dropping into mt disable.

– Use usbutils’ own ftdi parser for avalon and the ftdir’s own latency for

managing timeouts since we can wait on reads with completely asynchronous

reads+writes.

– Use usbutils’ own cps function for slowing rate of usb writes on avalon.

– Fix build for no libcurl

– Check length before submitting sync transfers
