- Added new option 1gb-pages in randomx object with command line equivalent --randomx-1gb-pages.
- Added automatic huge pages configuration on Linux if use the miner with root privileges.
Added automatic Intel prefetchers configuration on Linux.
- Added new option wrmsr in randomx object with command line equivalent --randomx-wrmsr=6.
#1396 #1401 New performance optimizations for Ryzen CPUs.
#1385 Added max-threads-hint option support for RandomX dataset initialization threads.
#1386 Added priority option support for RandomX dataset initialization threads.
For official builds all dependencies (libuv, hwloc, openssl) updated to recent versions.
Windows msvc builds now use Visual Studio 2019 instead of 2017.

v5.1.1

#1365 Fixed various system response/stability issues.
- Added new CPU option yield and command line equivalent --cpu-no-yield.
#1363 Fixed wrong priority of main miner thread.

v5.1.0

#1351 RandomX optimizations and fixes.
- Improved RandomX performance (up to +6-7% on Intel CPUs, +2-3% on Ryzen CPUs)
- Added workaround for Intel JCC erratum bug see https://www.phoronix.com/scan.php?page=article&item=intel-jcc-microcode&num=1 for details.
- Note! Always disable "Hardware prefetcher" and "Adjacent cacheline prefetch" in BIOS for Intel CPUs to get the optimal RandomX performance.
#1307 Fixed mining resume after donation round for pools with self-select feature.
#1318 Added option "mode" (or --randomx-mode) for RandomX.
- Added memory information on miner startup.
- Added resources field to summary API with memory information and load average.

v5.0.1

#1234 Fixed compatibility with some AMD GPUs.
#1284 Fixed build without RandomX.
#1285 Added command line options --cuda-bfactor-hint and --cuda-bsleep-hint.
#1290 Fixed 32-bit ARM compilation.

v5.0.0

This version is first stable unified 3 in 1 GPU+CPU release, OpenCL support built in in miner and not require additional external dependencies on compile time, NVIDIA CUDA available as external CUDA plugin, for convenient, 3 in 1 downloads with recent CUDA version also provided.

This release based on 4.x.x series and include all features from v4.6.2-beta, changelog below include only the most important changes, full changelog available separately.

#1272 Optimized hashrate calculation.
#1263 Added new option dataset_host for NVIDIA GPUs with less than 4 GB memory (RandomX only).
#1068 Added support for self-select stratum protocol extension.
#1227 Added new algorithm rx/arq, RandomX variant for upcoming ArQmA fork.
#808 Added experimental support for persistent memory for CPU mining threads.
#1221 Improved RandomX dataset memory usage and initialization speed for NUMA machines.
#1175 Fixed support for systems where total count of NUMA nodes not equal usable nodes count.
Added config option cpu/max-threads-hint and command line option --cpu-max-threads-hint.
#1185 Added JIT compiler for RandomX on ARMv8.
Improved API endpoint GET /2/backends and added support for this endpoint to workers.xmrig.info.
Added command line option --no-cpu to disable CPU backend.
Added OpenCL specific command line options: --opencl, --opencl-devices, --opencl-platform, --opencl-loader and --opencl-no-cache.
Added CUDA specific command line options: --cuda, --cuda-loader and --no-nvml.
Removed command line option --http-enabled, HTTP API enabled automatically if any other --http-* option provided.
#1172 Added OpenCL mining backend.
- #268 #270 #271 #273 #274 #1171 Added RandomX support for OpenCL, thanks @SChernykh.
Algorithm cn/wow removed, as no longer alive.
