 # FSL base project changelog
 
 
+## 2111.5 (Friday 19th November 2021)
+
+* Set `-std=c++14` for `nvcc`-compiled code, as CUDA 11.0 is the first version
+  to support `-std=c++17`, and we are targeting older CUDA versions.
+
+
 ## 2111.4 (Wednesday 17th November 2021)
 
 * The default C++ language standard is now `-std=c++17`.
