# 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**
- Added XLT v5/9 with autodetect(algo: "cryptonight", variant: "xtl" (autodetect), "xtlv9" (force v9))
- Added cn-lite variant UPX/uPlexa (algo: "cryptonight-lite", variant "upx")
- Added force-pow-variant parameter to force usage of the variant from the config and skip parsing of pow/variant from job/pool
* 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
- 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
