- Make it possible to enable/disable the status window from switching via the
display menu
- We should not update the tv hashmeter time unless we're updating the hashrates
- Add cointerra devices to udev rules.
- Use hashfast unique id instead of number since the unique id is displayed
- Remove displayed space
- Left align the displayed unique id
- Use the hashfast opname as its unique identifier
- Display BF1 serial number as its unique identifier

- Use an alternating status display to return to a compact width of 80
characters, allowing more information to be displayed.
- No need for looking for khash hashrates in summary any more
- Fix two potential minor mem leaks
- Fix memory leaks in setup and generate work for gbt solo.
- Fix off by one malloc size error
- Fix memory leak in update_gbt_solo
- Put sanity check on decay_time to prevent updates with no time
- Add 3 rolling average hashrates to API output for summary and devs.
- Use the extra status screen real estate better, displaying rolling 1/5/15min
average hashrates as well.
- Revamp the ageing crufty hashmeter code to have proper exponential decaying
values and store rolling 1/5/15min hashrates.
- Increment total_work under control lock.
- Trivial variable reuse
- Add support for other usb3 hubs on windows
Version 4.2.1 - 24th March 2014
- Fix various ava2 build issues generically
- Minimise the amount of heap memory allocations/frees when submitting gbt
shares.
- Make varint in gbt submission a stack object.
- Fix big endian problems with gbt submissions.
- Fix 32bit overflow on relative diff shown.
- ants1 - stop results read hard looping
- ants1 - slow down mining if overheat occurs
- miner.php allow gen before (bgen) and after (gen) grouping
- Change default solo mining to failing when no btc address is specified.
- Use upgrade cglock variants in get_gbt_curl
- Provide a cg_uilock to unlock the intermediate variant of cglocks.
- Use the one curl instance for all gbt solo operations, protecting its use with
a bool set under gbt lock.
- Only start block detection with gbt solo if setup succeeded
- One less block detection message
- Toss out the curl handle after each solo poll
- Don't reuse any curl handles for solo mining and break out of the lp thread if
the pool is removed.
- Make sure to only start the lognpoll thread once on gbt solo.
- Don't keep RPC connections open for solo mining since bitcoind doesn't like
having many persistent connections.
- GBT solo pools should be considered localgen pools.
- miner.php - speed up formatting and allow calc on gen fields
- Always show the address we're solo mining to to avoid confusion for when no
address is set.

- Decrease the time we wait for unsetting a core on the cta bitmap to correspond
with the lower max diff of 32.
- Set max diff on cointerra devices to 32 which is still only 11 shares per

of pool work difficulty for more accurate hashrates.
- Since the device runtime is now reset, the Raw hashrate entry in the cta API
output is no longer meaningful.

it being invalid.

init frame since it will be dropped regardless.

possible.
- Read off the OP_NAME if it exists and is supported on hfa devices, setting it
to the device serial number or a timestamp if it is invalid.
- Updated hf protocol
- Check for an amount along with no error in hfa clear readbuf
- Hfa clear readbuf can return a nonsense amount when there's a return error so
ignore the amount.
- Running resets always cause a shutdown on hfa meaning the device will
disappear with modern firmware so always kill off the threads to allow
re-hotplugging.
- Reset the hfa hash clock rate to the old one if we find an old instance, only
setting the device id in hfa_prepare

failure.

Version 3.9.0 - 23rd December 2013
- drillbit asic - enable in api.c
- Fix trivial warnings in knc driver.
- Reinstate work utility based hashmeter for knc.
- drillbit format %z not valid on windows
- drillbit more formatting changes
- usbutils remove old code added back
- Memset the spi tx buffer under lock in knc driver.
- drillbit fix temp display to fit in standard space
- Drillbit formatting
- drillbit - use one drvlog and display dname before add_cgpu
- Keep orginal naming for the bitfury driver
- knc: Bugfix - good shares wrongly reported as HW errors. Root cause of the
problem: several work items were assigned the same work_id in the active works
queue of the knc driver. Thus when good nonce report arrived from the FPGA,
wrong work item was picked up from the queue, and submit_nonce evaluated that
as an error. Fix: Limit the work_id counter update rate. Update it only to the
number of works actually consumed by the FPGA, not to the number of works
send.
- Store per-chip submit information for bxf device and show them in the API.
- Check for removed bxf devices before trying to update work or send messages.
- api.c no decref if not json
- Minimise risk of nonce2 overflow with small nonce2 lengths by always encoding
the work little endian, and increasing the maximum size of nonce2 to 8 bytes.
- Change default hashfast timeout to 500ms.
- Ensure we can look up the work item in the hashfast driver or print out an
error if we don't.
- Drillbit source formatting - reindent and retabify
- Add ASIC count, temperature status to drillbit API output (closes #1)
- Many warning fixes
- knc: Do not include variable "last minute" data into the "last hour" per-core
stats
- knc: Make per-core statistics available through API
- Implement command line control of the bxf target temperature.
- Add a simple PID-like controller to bi*fury devices to dynamically alter the
clock setting to maintain a nominal target temperature set to 82 degrees.
- Add data to BXF API output.
- Add support for newer protocol bi*fury commands job, clock and hwerror,
setting clock to default 54 value, turning parsing into a compact macro.
- Look for the thermal overload flag in the gwq status message in the hashfast
driver and send it a shutdown followed by an attempted reset.
- Log message fixups
- Fix for "Timing out unresponsive ASIC" for pools which send early reconnect
requests, and then take a short time to send work (ie BTCGuild)
- Shorten initial config line, win32/pdcurses doesn't like long lines during
early logging

- Align device status lines same regardless of number of temp status or >10
ASICs

- Print a summary of the device settings at level NOTICE during initialisation
- Allow chosing device settings based on 'short' product names shown in status
line
- Allow per-device settings to use "DRBnn" as an identifier instead
- Issue an ASIC restart during a work_restart, removes spurious timeout messages
from ASICs and probably some rejected shares
- Check all results against all work instead of just taking the first match
(avoids some rejected submissions to the pool, ASIC can produce multiple
candidate results.)
- Fix memory leak caused by unnecesarily copied work
