# v5.4.0
- [#1434](https://github.com/xmrig/xmrig/pull/1434) Added RandomSFX (`rx/sfx`) algorithm for Safex Cash.
- [#1445](https://github.com/xmrig/xmrig/pull/1445) Added RandomV (`rx/v`) algorithm for *new* MoneroV.
- [#1419](https://github.com/xmrig/xmrig/issues/1419) Added reverting MSR changes on miner exit, use `"rdmsr": false,` in `"randomx"` object to disable this feature.
- [#1423](https://github.com/xmrig/xmrig/issues/1423) Fixed conflicts with exists WinRing0 driver service.
- [#1425](https://github.com/xmrig/xmrig/issues/1425) Fixed crash on first generation Zen CPUs (MSR mod accidentally enable Opcache), additionally now you can disable Opcache and enable MSR mod via config `"wrmsr": ["0xc0011020:0x0", "0xc0011021:0x60", "0xc0011022:0x510000", "0xc001102b:0x1808cc16"],`.

- 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](https://github.com/xmrig/xmrig/issues/1365) Fixed various system response/stability issues.
- Added new CPU option `yield` and command line equivalent `--cpu-no-yield`.
