Hi community 
With v3, we are planning to remove large parts of the action functionality of preCICE as these are rarely used and hard to maintain.
Envisioned changelog entry:
- Removed deprecated action timings
regular-prior, regular-post, on-exchange-prior, and on-exchange-post.
- Removed action timings
read-mapping-prior, write-mapping-prior, and on-time-window-complete-post.
- Removed
ComputeCurvatureAction action.
- Removed callback functions
vertexCallback and postAction from PythonAction interface.
Previous functionality:
Please protest if you rely on any of this functionality.
