The FEniCS Project Steering Council is pleased to announce the release 
of version 2019.1.0 of the FEniCS Project https://fenicsproject.org. 
Installation instructions are available at https://fenicsproject.org/download.

FEniCS Project 2019.1.0 includes new functionality for calculating shape 
derivatives and support for PETSc and SLEPc versions 3.11. We would 
like to take this opportunity thank the community for their many 
contributions.

The FEniCS Project is currently undergoing a major redevelopment 
codenamed FEniCS-X. You can read more about this effort at 
https://fenicsproject.org/fenics-project-roadmap-2019/

FEniCS is a popular open-source (LGPLv3) computing platform for solving 
partial differential equations (PDEs). FEniCS enables users to quickly and 
automatically translate scientific models into efficient finite element code. 

The FEniCS Project is a fiscally sponsored project of NumFOCUS 
(https://numfocus.org).
