# 2.0.0
**Thx to @xmrig and @SChernykh awesome work!**
* Full Rebase on XMRig 3.1.1
* randomX/wow/XL
* NUMA support
* flexible multi algorithm configuration
* unlimited switching between incompatible algorithms at runtime
* Argon2, UPX2 (Nice hashrate improvement) and CN-Conceal support integrated like in previous version
* 5-10% Hashrate improvement on ARMv8 CPUs when mining CN based algos compared to stock xmrig
* Fully compatible to XMRigCCServer 1.9.5 no server upgrade needed!
**New XMRigCCServer will be released soon with new features**
* Hashrate improve -> add autodetection mode for cpu-affinity
* Hashrate improve, more stable hashrates -> refactor memory allocation
* Add TubeV4 support (cn-heavy + ipbc mod + soft-aes mod)
* Update ccp-httpd lib to fix stop/freeze of cc communication on some miners
* Fix cn-heavy on arm processors
- Added shift+click function for multi row selection to Dashboard
- Added -DBUILD_STATIC=ON/OFF option to CMake configuration to create fully static builds
- Added current algo and list of supported_varaints to login message for future usage on proxy
- Added support for latest Stellite (XTL) and Alloy (XAO) variants
- Simplification of configuration, "force-pow-variant" and "cryptonight-lite-ipbc" parameters are now deprecated see [Coin Configuration](https://github.com/Bendr0id/xmrigCC/wiki/Coin-configurations) for guidance
- Fixed leaks in transport shutdown
* Debouncing of connection retry when connecting donation server fails
* When PoW variant is set on proxy, it will overrule local set PoW
* Implementation of cn_heavy algo
* Added self test for cn-heavy
* Fixed n-loop variant of powV2 and cn-heavy
* Fixed n-loop variant of powV2 and added cn-heavy for ARM
* Fixing n-loop for arm
* Limited cn-heavy to max hashfactor 3 on higher seltest fails.
* Removed a lot of casts
* Fixed algo selftest
- Fixed CPU affinity on Windows for NUMA and CPUs with lot of cores
- Implemented per thread configurable Multihash mode (double, triple, quadruple, quintuple)
- Rebased from XMRig 2.4.4
