# 2.4. Version 5.18 (2024/02/23)

New Features:

  - Lagrangian particle thermophoresis: particle momentum source terms can now optionally include thermophoretic force contributions for Lagrangian particles

Bug Fixes:

  - L2 norm postprocessor fixed to allow intermediate variables in the string function

  - Reported mass flow rate in log file when using multiple open boundary conditions was incorrect

  - Fixed error in non-unity Lewis laminar species transport model

  - Fixed stress tensor trace scaling in 2D for various turbulence models

  - Fixed bug in flux post-processor reduction for parallel-shared nodes

Upcoming Deprecations (will warn in 5.18)

  - Using Nalu for participating media radiation is deprecated. Use `pmr` instead.

  - Using encore post-processors is deprecated - use the `Begin Postprocess` blocks in the Fuego Region.

  - Zero and Second order projection methods are deprecated.

  - The `Number of logged clipping events` command no longer has any effect and will be removed in a future release.
