+# v2.99.1-beta
+- [#1072](https://github.com/xmrig/xmrig/issues/1072) Fixed RandomX `seed_hash` re-initialization.
+
+# v2.99.0-beta
+- [#1050](https://github.com/xmrig/xmrig/pull/1050) Added RandomXL algorithm for [Loki](https://loki.network/), algorithm name used by miner is `randomx/loki` or `rx/loki`.
+- Added [flexible](https://github.com/xmrig/xmrig/blob/evo/doc/CPU.md) multi algorithm configuration.
+- Added unlimited switching between incompatible algorithms, all mining options can be changed in runtime.
+- Breaked backward compatibility with previous configs and command line, `variant` option replaced to `algo`, global option `algo` removed, all CPU related settings moved to `cpu` object.
+- Options `av`, `safe` and `max-cpu-usage` removed.
+- Algorithm `cn/msr` renamed to `cn/fast`.
+- Algorithm `cn/xtl` removed.
+- API endpoint `GET /1/threads` replaced to `GET /2/backends`.
+
+# v2.16.0-beta
+- [#1036](https://github.com/xmrig/xmrig/pull/1036) Added RandomWOW (RandomX with different preferences) algorithm support for [Wownero](http://wownero.org/).
+  - Algorithm name used by miner is `randomx/wow` or `rx/wow`.
+  - Currently runtime algorithm switching NOT supported with other algorithms.
+
+# v2.15.4-beta
+- Added global uptime and extended connection information in API.
+- API now return current algorithm instead of global algorithm specified in config.
+- This version also include all changes from stable version v2.14.4.
+
+# v2.15.3-beta
+- [#1014](https://github.com/xmrig/xmrig/issues/1014) Fixed regression, default value for `algo` option was not applied.
+
+# v2.15.2-beta
+- [#1010](https://github.com/xmrig/xmrig/pull/1010#issuecomment-482632107) Added daemon support (solo mining).
+- [#1012](https://github.com/xmrig/xmrig/pull/1012) Fixed compatibility with clang 9.
+- Config subsystem was rewritten, internally JSON is primary format now.
+- Fixed regression, big HTTP responses was truncated.

 # v2.15.1-beta
 - [#1007](https://github.com/xmrig/xmrig/issues/1007) Old HTTP API backend based on libmicrohttpd, replaced to custom HTTP server (libuv + http_parser).
 - [#257](https://github.com/xmrig/xmrig-nvidia/pull/257) New logging subsystem, file and syslog now always without colors.

- * [Full table for supported algorithm and variants.](https://github.com/xmrig/xmrig-proxy/blob/master/doc/STRATUM_EXT.md#14-algorithm-names-and-variants)
+Since version 3 mining [algorithm](#algorithm-names) should specified for each pool separately (`algo` option), earlier versions was use one global `algo` option and per pool `variant` option (this option was removed in v3). If your pool support [mining algorithm negotiation](https://github.com/xmrig/xmrig-proxy/issues/168) you may not specify this option at all.

+# CPU backend
+
+All CPU related settings contains in one `cpu` object in config file, CPU backend allow specify multiple profiles and allow switch between them without restrictions by pool request or config change. Default auto-configuration create reasonable minimum of profiles which cover all supported algorithms.
+
+### Example
+
+Example below demonstrate all primary ideas of flexible profiles configuration:
+
+* `"rx/wow"` Exact match to algorithm `rx/wow`, defined 4 threads without CPU affinity.
+* `"cn"` Default failback profile for all `cn/*` algorithms, defined 2 threads with CPU affinity, another failback profiles is `cn-lite`, `cn-heavy` and `rx`.
+* `"cn-lite"` Default failback profile for all `cn-lite/*` algorithms, defined 2 double threads with CPU affinity.
+* `"custom-profile"` Custom user defined profile.
+* `"*"` Failback profile for all unhandled by other profiles algorithms.
+* `"cn/r"` Exact match, alias to profile `custom-profile`.
+* `"cn/0"` Exact match, disabled algorithm.
+

+This option was known as `low_power_mode`, possible values is range from 1 to 5, for convinient if value 1 used, possible omit this option and specify CPU thread config by only one number: CPU affinity, instead of object.
