# DORiE Changelog ## Unreleased ### Added * DORiE now employs a `SubsamplingVTKWriter` for higher output precision. Subsampling levels are controlled via the new key `output.subsamplingLevel`. * Automatic deployment of `devel` and stable DORiE Docker Images to Docker Hub * Automatic update of the DUNE environment Docker Image for `master` builds * CI pipeline now also compiles a Debug build with the LLVM Clang compiler * Add `.gitattributes` for `CHANGELOG.md` to reduce merge conflicts with `merge=union` * Public API definition in documentation. ### Changed * Update code base to DUNE v2.6 * Raise software requirements to versions available on Ubuntu 18.04 LTS (Bionic Beaver) * Switch VTK output from conforming to non-conforming * Use `multicore` build tag only for `test:parallel` build because the current GitLab Runner cannot handle the load * Use the `OVLP_AMG_4_DG` linear solver for all computations, including sequential ones. This significantly improves performance for large problems. * Change compilation order which reduces RAM usage when compiling in parallel. * Decentralization of the header system so that in most of the header files are independent of each other ### Deprecated * `output.subsamplingLevel` is optional and defaults to 0 if not given explicitly in the config file. The key will become mandatory in future versions. ### Removed * Complete doxygen documentation from Sphinx docs. ### Fixed * The source code is now compatible to the Clang LLVM compiler. DORiE can now be compiled with the onboard compiler on macOS. * Fix finite element map used for simplex grids. The old one did not implement a discontinuous function space. * Allow warnings on ParMETIS not being available for parallel computations. ## 1.0.0 (2018-03-28) First stable version
