Version 1.2.6 - July 15, 2011 |
|
|
|
- Put a current system status line beneath the total work status line |
|
- Fix a counting error that would prevent cgminer from correctly detecting |
|
situations where getwork was failing - this would cause stalls sometimes |
|
unrecoverably. |
|
- Limit the maximum number of requests that can be put into the queue which |
|
otherwise could get arbitrarily long during a network outage. |
|
- Only count getworks that are real queue requests. |
|
|
|
|
|
Version 1.2.5 - July 15, 2011 |
|
|
|
- Conflicting -n options corrected |
|
- Setting an intensity with -I disables dynamic intensity setting |
|
- Removed option to manually disable dynamic intensity |
|
- Improve display output |
|
- Implement signal handler and attempt to clean up properly on exit |
|
- Only restart threads that are not stuck waiting on mandatory getworks |
|
- Compatibility changes courtesy of Ycros to build on mingw32 and osx |
|
- Explicitly grab first work item to prevent false positive hardware errors |
|
due to working on uninitialised work structs |
|
- Add option for non curses --text-only output |
|
- Ensure we connect at least once successfully before continuing to retry to |
|
connect in case url/login parameters were wrong |
|
- Print an executive summary when cgminer is terminated |
|
- Make sure to refresh the status window |
|
|

|
|
|
Version 1.0.1 - May 14, 2011 |
|
|
|
- OSX support |
|
|
|
Version 1.0 - May 9, 2011 |
|
|
|
- jansson 2.0 compatibility |
|
- correct off-by-one in date (month) display output |
|
- fix platform detection |
|
- improve yasm configure bits |
|
- support full URL, in X-Long-Polling header |
|
|
|
Version 0.8.1 - March 22, 2011 |
|
|
|
- Make --user, --pass actually work |
|
|
|
- Add User-Agent HTTP header to requests, so that server operators may |
|
more easily identify the miner client. |
|
|
|
- Fix minor bug in example JSON config file |
|
|
|
Version 0.8 - March 21, 2011 |
|
|
|
- Support long polling: http://deepbit.net/longpolling.php |
|
|
|
- Adjust max workload based on scantime (default 5 seconds, |
|
or 60 seconds for longpoll) |
|
|
|
- Standardize program output, and support syslog on Unix platforms |
|
|
|
- Suport --user/--pass options (and "user" and "pass" in config file), |
|
as an alternative to the current --userpass |
|
|
|
Version 0.7.2 - March 14, 2011 |
|
|
|
- Add port of ufasoft's sse2 assembly implementation (Linux only) |
|
This is a substantial speed improvement on Intel CPUs. |
|
|
|
- Move all JSON-RPC I/O to separate thread. This reduces the |
|
number of HTTP connections from one-per-thread to one, reducing resource |
|
usage on upstream bitcoind / pool server. |
|
|
|
Version 0.7.1 - March 2, 2011 |
|
|
|
- Add support for JSON-format configuration file. See example |
|
file example-cfg.json. Any long argument on the command line |
|
may be stored in the config file. |
|
- Timestamp each solution found |
|
- Improve sha256_4way performance. NOTE: This optimization makes |
|
the 'hash' debug-print output for sha256_way incorrect. |
|
- Use __builtin_expect() intrinsic as compiler micro-optimization |
|
- Build on Intel compiler |
|
- HTTP library now follows HTTP redirects |
|
|
|
Version 0.7 - February 12, 2011 |
|
|
|
- Re-use CURL object, thereby reuseing DNS cache and HTTP connections |
|
- Use bswap_32, if compiler intrinsic is not available |
|
- Disable full target validation (as opposed to simply H==0) for now |
|
|
|
Version 0.6.1 - February 4, 2011 |
|
|
|
- Fully validate "hash < target", rather than simply stopping our scan |
|
if the high 32 bits are 00000000. |
|
- Add --retry-pause, to set length of pause time between failure retries |
|
- Display proof-of-work hash and target, if -D (debug mode) enabled |
|
- Fix max-nonce auto-adjustment to actually work. This means if your |
|
scan takes longer than 5 seconds (--scantime), the miner will slowly |
|
reduce the number of hashes you work on, before fetching a new work unit. |
|
|
|
Version 0.6 - January 29, 2011 |
|
|
|
- Fetch new work unit, if scanhash takes longer than 5 seconds (--scantime) |
|
- BeeCee1's sha256 4way optimizations |
|

|

|
Version 0.5 - December 28, 2010 |
|
|
|
