# Release news ## Version 4.2.2 - 27th June 2014 * Fixes for a few stratum-related security vulnerabilities (reported by _Mick Ayzenberg_ of DejaVu Security). * Found blocks calculation fix (by _troky_). ## Version 4.2.1 - 22nd May 2014 * Fixed MSVS building, tested with MSVC++ 2010 and 2013 (by _troky_). * Added the "ultratune" feature from `sph-sgminer`, available in the NCurses interface with `[G][C][U]` (by _ultracorp_). ## Version 4.2.0 - 20th May 2014 * git repo moved to [sgminer-dev](https://github.com/sgminer-dev/sgminer). It is now a GitHub organisation with several people having write access. * Kernel `bufius` merger from `vertminer` (by _Bufius_). * Set pool as idle on several stratum failure conditions (by _elbandi_). * API response to `version` has field `CGMiner` instead of `SGMiner` for API client compatibility, and an additional `Miner` field (by _luke-jr_). * API response to `restart` and `quit` only contains a `status` section and passes JSON validation (by _luke-jr_). * API response to `devs` contains `XIntensity` and `RawIntensity` fields. * Config file writing from TUI/API should produce a borked config less often. ## Version 4.1.271 - 12th April 2014 * Allow setting algorithm per-pool and initial implementation of kernel hot-swapping (by _mrbrdo_). Use options `pool-algorithm` (in config file or in CLI) or `algorithm` (config-only). * NCurses UI `[S][W]` writes pool name and description to configuration. * Added algorithm name to `pools` API command (by _troky_). * NCurses UI asks for (optional) pool name, description and algorithm when adding pool. * API command `addpool` allows both `url,user,pass` and `url,user,pass,name,desc,algo`. ## Version 4.1.242 - 7th April 2014 * There are now two mailing lists (on SourceForge), see `README.md`. * Adaptive-N-factor algorithm support (by _Bufius_, _Zuikkis_ and _veox_). For details on choosing the algorithm, see `doc/configuration.md`. * Allowed kernel names are no longer hard-coded. It is now possible to use any `.cl` file. * Configuration parameter `poolname` has been renamed to `name`. `poolname` is deprecated and will be removed in a future version. * Multiple `--name` parsing should now work as expected (by _troky_). * `--description` configuration parameter to specify a freeform pool description, and `--priority` to specify the pool's priority (by _troky_). ## Version 4.1.153 - 14th March 2014 * Display pool URL instead of "Pool N" if no `poolname` specified. * Incognito mode to hide user name in NCurses interface - useful for publishing screenshots. To enable, use `--incognito` on command line, `incognito` in config or `[D][I]` in NCurses interface. * Support building in Microsoft Visual Studio 2010, perhaps other versions as well (by _troky_). Documentation in `winbuild/README.txt`. * Support building in Cygwin (by _markuspeloquin_). Documentation in `doc/cygwin-build.txt`. * Forward-port changes from `ckolivas/cgminer` up to 3.12.3. * Allow setting `worksize` for kernel `zuikkis`. * More log messages in pool handling. * Updated `doc/FAQ.md`. * Updated `example.conf`. ## Version 4.1.0 - 7th February 2014 * Writing configuration file from NCurses interface is broken! * Commandline option parsing may be broken! * MinGW building may be broken! * Bug reporting documentation: `doc/BUGS.md`. * Kernel selection and integration: `doc/KERNEL.md`. * Several updates to other documentation files. * Warn if `GPU_*` environment variables are not set. * Maximum `intensity` lowered to 31 (anything above that gives an overflow anyway). * Experimental `xintensity` setting (by _Kalroth_), see [commit message](https://github.com/veox/sgminer/commit/7aeae40af22e6108aab8b68a229eea25a639d650). * Experimental `rawintensity` setting (by _Kalroth_), see [commit message](https://github.com/veox/sgminer/commit/d11df698d141988491494aa1f29c7d3595e9712b). * `-v` is now a shorthand for `--verbose`, not `--vectors`. * Default `scantime` and `expiry` changed to 7 and 28 (tests run by _MissedOutOnBTC_). * Increased precision of `API_MHS`; added `API_KHS`. * Pulled in kernels: `alexkarold`, `alexkarnew`, `psw`, `zuikkis`; renamed `scrypt` to `ckolivas`; all kernels now reside in directory `kernel`. Kernels can be chosen at startup only, by specifying `kernel`. * Small optimisation to `ckolivas` kernel (by _gdevenyi_). * Named pools via `poolname` (by _Kalroth_). * Failover pool switching back delay is configurable via `failover-switch-delay` (by _Kalroth_). * Pool `state`: `enabled`, `disabled`, and `hidden` (by _Joe4782_). * Allow all pools to be set `disabled`. * Use RPM in ADL `get-fanspeed` requests (from `bfgminer`, by _luke-jr_). * Verbose ADL failure messages (by _Joe4782_ and _deba12_). * Use `git` version string if available. * Allow bypassing ADL checks during build with `--disable-adl-checks`. * MinGW build checks (by _tonobitc_). * Experimental Microsoft Visual Studio 2010 building support in branch `build-msvs2010-upd` (by _troky_). ## Version 4.0.0 - 15th January 2014 * Fork `veox/sgminer` from `ckolivas/cgminer` version 3.7.2. * Remove code referencing SHA256d mining, FPGAs and ASICS. Leftovers most probably still remain. * AMD ADL crash fix on R9 chipsets by Benjamin Herrenschmidt. * Maximum allowed intensity increased to 42. * Move documentation to directory `doc`. * `--gpu-threads` support for comma-separated values by Martin Danielsen (_Kalroth_). * AMD ADL SDK 5 mandatory, preparation for ADL Overdrive 6 support by _Kalroth_. * Allow changing TCP keepalive packet idle time using `--tcp-keepalive`. * Automatic library presence detection by `configure`. * `--scrypt` option removed (no other choice now). * `--vectors` option removed (current kernel only supports 1). * Display per-GPU reject percentage instead of absolute values by _Kalroth_. * Do not show date in log by default (switch with `--log-show-date`). * Fix network difficulty display to resemble that of `cgminer` 3.1.1. * Forward-port relevant bugfixes form `ckolivas/cgminer`, up to `cgminer` version 3.10.0.
