 ## Migration to v3
 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.

+Version 2.2.0
+-------------
+* API
+  + Add hwloc_bitmap_singlify_by_core() to remove SMT from a given cpuset,
+    thanks to Florian Reynier for the suggestion.
+  + Add --enable-32bits-pci-domain to stop ignoring PCI devices with domain
+    >16bits (e.g. 10000:02:03.4). Enabling this option breaks the library ABI.
+    Thanks to Dylan Simon for the help.
+* Backends
+  + Add support for Linux cgroups v2.
+  + Add NUMA support for FreeBSD.
+  + Add get_last_cpu_location support for FreeBSD.
+  + Remove support for Intel Xeon Phi (MIC, Knights Corner) co-processors.
+* Tools
+  + Add --uid to filter the hwloc-ps output by uid on Linux.
+  + Add a GRAPHICAL OUTPUT section in the manpage of lstopo.
+* Misc
+  + Use the native dlopen instead of libltdl,
+    unless --disable-plugin-dlopen is passed at configure time.
