|
|
|
+same device
|

+statline
|
|

|
|
+(used by modminer/x6500 for upload %)

|
+- TUI: Replace DevAPI statline_before with a predefined temperature column to
|
|
|
+free up statline space

|
|
+- erupter: New icarus-based driver to handle autodetection of Block Erupter

|
|
|
+the commandline or config file
|
|
|
+- Detect staged work underruns and increase queue to avoid them

+drv:[no]auto can be used for the same purposes
|
|
|
+- Bugfix: Since at least one of unix (or __APPLE__) or WIN32 is required by
|
|
|
+util.h, make sure unix is defined if WIN32 is not
|
|
|
+- Bugfix: Set ELF rpath for bundled libblkmaker to use $ORIGIN so it can be run
|
|
|
+from other directories
|
|
|
+- Bugfix: Cleanup needs to happen before printing the final quit message, or it
|
|
|
+gets lost in TUI mode
|
|

|
|
|
+that want to report initialization status in their statline
|
|
|
+- Bugfix: modminer: Only program once for --force-dev-init

|
|
+- cpu & opencl: Respect scan-serial auto/noauto instructions

|
|
|
+- Split out per-cgpu temperature configuration code to load_temp_config_cgpu

|
|
|
+be done without touching live variables

|
|
|
+are not in older versions of pyserial
|
|
|

|
|
|
+until there are fewer
|
|
|
+- Bugfix: Initialization for bfgtls needs to be done in each thread
|
|
|
+- Bugfix: stratum: Be patient with stratum lines that come in slower than we can
|
|
|
+process them
|
|

+- Use bfg_strerror in locations previously just logging raw error numbers
|
|
|
+- Bugfix: stratum: Log WSAGetLastError() for error number on recv failures on
|
|
|
+Windows
|
|
|

|
+- New thread-safe bfg_strerror function to portably stringify error codes
