 ### Current priority: 
 
+- [ ] Numpy-like arrays for multi-dimensional DTW.
 - [ ] If you accidentally compile with amd64_x86 you get bad_alloc due to the insufficient RAM in 32-bit computer. So, put a warning for that. 
 - [ ] Modernise `*.csv` reading interface, allow for rowwise or columnwise data. 
 - [x] CMake files arranging:
   - [x] HiGHS 1.6.0 does not always work. Also it does not work in debug mode due to iterator level.

+## Versioning: 
+
+We use semantic versioning with MAJOR.MINOR.PATCH where:
+
+- PATCH: Backwards compatible bug fix without introducing a new feature. 
+- MINOR: Backwards compatible new feature. 
+- MAJOR: Incompatible changes, especially on API. 
+
+See [this link](https://www.youtube.com/watch?v=xvPiZyx0cDc) for a detailed tutorial on versioning.
