Dear preCICE community,

We are happy to announce a new bugfix preCICE release v3.1.2.

This is only relevant for users coupling participants with implicit and explicit schemes simultaneously.

We fixed a bug which exchanged data of the first iteration with explicitly coupled participants instead of postponing the data exchange until the implicit scheme has successfully converged.
This fix may also impact runtime performance as the aforementioned explicitly coupled participants now need to wait longer. Therefore, their runtime may not overlap the way it did before.

For all details, check the full list of changes in the changelog.

Happy coupling!
