+- Changes relevant for users:
+  - **PLUMED 2.10 requires a C++17 compatible compiler**.
+  - It is now possible to use an embedded Python interpreter to implement collective variables and functions in Python. This is largely based on a previous implementation by Toni Giorgino
+    that is described in [this paper](https://joss.theoj.org/papers/10.21105/joss.01773) and has been integrated in PLUMED by Daniele Rapetti. This feature is provided as a separate plugin
+    that can be linked against the proper Python interpreter and loaded at runtime with \ref LOAD. Documentation about how to install and use this feature can be found in directory
+    `plugins/pycv`.
+  - A prototype of the \ref COORDINATION collective variable with limited functionalities is now included in a CUDA implementation which is orders of magnitude faster
+    when using large groups. This implementation has been contributed by Daniele Rapetti and is provided as a separate plugin
+    that can be linked against the proper CUDA libraries and loaded at runtime with \ref LOAD. Documentation about how to install and use this feature can be found in directory
+    `plugins/cudaCoord`.
 
 - Changes relevant for developers:
   - Removed some shortcuts for `ActionRegister.h` (from the modules bias colvar function sasa and vatom) and `CLToolRegister.h` (from the module cltools), now the two headers can only be included with `#include "core/ActionRegister.h"` or `#include "core/CLToolRegister.h"`.

   - On Linux, `plumed-runtime` executable can now find a working libplumedKernel.so by looking in the `dlopen` path (including `LD_LIBRARY_PATH` and stored RPATH).
     On MacOS, `plumed-runtime` executable can now find a working libplumedKernel.dylib by using a relative rpath.
     These changes should make this executable as functional as the normal `plumed` executable but with the advantage of loading symbols in a local namespace (see above).
+  - A new \ref benchmark tool has been added to time execution of sample input files and facilitate the comparison across multiple PLUMED versions.
