* can build without microhttpd when WITH_HTTPD=OFF * #341 Fix wrong exit code. * +15% boost with non-AES CPU Performance boost validated on Core 2 Quad processor under Windows 10. But it's Windows/MS Visual C++ specific. * #341 Added option --dry-run. * Remove compilation warnings under MSVC * up to 20% perf increase with Cryptonight with non-AES CPU This time, the performance increase is got with MSVC and GCC. On non-AES CPU, there were an useless load/store SSE2 register. The last MSVC "hack" is replaced by a portable code and he's more complete (a load is saved). On my C2Q6600, with 3 thread, I have +16% with MSVC2015 and +20% with GCC 7.3, compared to official 2.4.4 version. * Compilation error under FreeBSD ULONG is not recognized under this OS, so replaced it with more portable definition. * Update README.md * Update README.md * Update README.md * Correct L2 cache size calculation for Intel Core 2 family This is a workaround for total L2 cache size calculation of Intel Core Solo, Core Duo, Core 2 Duo, Core 2 Quad and their Xeon homologue. These processors have L2 cache shared by 2 cores. There is maybe more CPU with L2 shared cache, but I am sure that these models are concerned and they are not so numerous. A better way would be to modify libcpuid to implement L2 cache counting. * Fix code style, replace tabs to space. * Fix code style, replace tabs to space #2. * Update README.md * Update CHANGELOG.md * Update README.md * Update README.md * v2.4.5 RC * Update CHANGELOG.md * Run internal http server in main loop to avoid requirement to thread synchronization. * Added XMRIG_DEPS cmake variable for unified dependencies. * Use adaptive timer instead of idle handler for HTTP server. * Changes for the Monero v1 PoW * #428 Fixed regression with CPU cache size detection. * Fixed regression (all versions since 2.4 affected) fragmented responses from pool/proxy parsed incorrectly. * Update copyright and move version into Job class. * PoW changes WIP * Added reference hashes. * Added full IPv6 support. * Added option to disable Monero v7 PoW, may useful in future if other coins update their network to v7 without PoW change. * Automatically enable nicehash when use with upcoming xmrig-proxy 2.5. * Added coin field support added in xmrig-proxy 2.5. * Update CHANGELOG.md * Update CHANGELOG.md * Revert changes in Api class, single threaded http server will not be included in 2.5 release. * v2.5.0-dev * Change donation address to separate old and new versions. * Some small fixes. * Better v1 PoW implementation, added variant option. * Added test hashes for AEON. * Change port for AEON donate. * Add -DBUILD_STATIC=ON for static builds See #238 * Simplify variant selection. * #438 Fixed memory release. * Fix for previous commit. * Fix FindUV.cmake and FindMHD.cmake. * Fixes for 32 bit gcc builds. * Remove align.h. * Fix. * Fix FindMHD.cmake * Fix macOS compile. * v2.5.0 * Update README.md * Update README.md
