# 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](https://github.com/xmrig/xmrig-cuda), 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](doc/CHANGELOG_OLD.md) available separately.

- [#1272](https://github.com/xmrig/xmrig/pull/1272) Optimized hashrate calculation.
- [#1263](https://github.com/xmrig/xmrig/pull/1263) Added new option `dataset_host` for NVIDIA GPUs with less than 4 GB memory (RandomX only).
- [#1068](https://github.com/xmrig/xmrig/pull/1068) Added support for `self-select` stratum protocol extension.
- [#1227](https://github.com/xmrig/xmrig/pull/1227) Added new algorithm `rx/arq`, RandomX variant for upcoming ArQmA fork.
- [#808](https://github.com/xmrig/xmrig/issues/808#issuecomment-539297156) Added experimental support for persistent memory for CPU mining threads.
- [#1221](https://github.com/xmrig/xmrig/issues/1221) Improved RandomX dataset memory usage and initialization speed for NUMA machines.
- [#1175](https://github.com/xmrig/xmrig/issues/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](https://github.com/xmrig/xmrig/pull/1185) Added JIT compiler for RandomX on ARMv8.
- Improved API endpoint `GET /2/backends` and added support for this endpoint to [workers.xmrig.info](http://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](https://github.com/xmrig/xmrig/issues/1172) **Added OpenCL mining backend.**
  - [#268](https://github.com/xmrig/xmrig-amd/pull/268) [#270](https://github.com/xmrig/xmrig-amd/pull/270) [#271](https://github.com/xmrig/xmrig-amd/pull/271) [#273](https://github.com/xmrig/xmrig-amd/pull/273) [#274](https://github.com/xmrig/xmrig-amd/pull/274) [#1171](https://github.com/xmrig/xmrig/pull/1171) Added RandomX support for OpenCL, thanks [@SChernykh](https://github.com/SChernykh).
- Algorithm `cn/wow` removed, as no longer alive.
