+# v2.10.0
+- [#904](https://github.com/xmrig/xmrig/issues/904) Added new algorithm `cn-pico/trtl` (aliases `cryptonight-turtle`, `cn-trtl`) for upcoming TurtleCoin (TRTL) fork.
+
 # v2.9.4
 - [#913](https://github.com/xmrig/xmrig/issues/913) Fixed Masari (MSR) support (this update required for upcoming fork).
