# 2.9. Version 5.14 (2023/05/29)

New Features

  - Contact between faces that are no longer geometrically in contact is now supported. An example of this is applying contact to a periodic domain. See Periodic Contact for information on how to use this feature.

  - Contact enforcements can now be used to impose a prescribed offset across a contact interface. This can be useful in both standard contact problems and for vector/tensor DOFs in Periodic Contact problems. See Offset Quantities for information on how to use this feature.

  - User fields can now be smoothed after transfer by specifying a number of iterations in the `USER FIELD` line.

Upcoming Deprecations (will warn in 5.14)

  - The legacy line commands for specifying contact material models have been deprecated in favor of the their generic material syntax equivalents. See Contact Materials for more details on specifying these commands. Note that the deprecation messages should also offer exact conversions to the new syntax.

  - The `Using data specification` command for flux BCs is deprecated - use the required parameters directly.

New Deprecations (will error in 5.14)

  - Coupling with Scefire is deprecated - use Sierra/PMR instead.
