• Jenkins shows nice summaries of compiler warnings. #2206
• Large tests are fixed and run on Jenkins upon master merge. #2056, #2155
• Re-enabled code coverage reports (for the testrunner only) with Codecov. #2333, #2336
• Commits containing [ci skip] in the commit message do not trigger a Jenkins build.
• Add vtkdiff test configuration to project files, s.t. the vtkdiff tests are performed after successful run comparing output to reference files. This possibility is also reflected in a new CMake function OgsTest as an alternative to the AddTest. #2255, #2257

New tools

• Mesh2Raster: converts 2D OGS meshes into raster files of arbitrary pixel size, where node elevation is represented by pixel value. #2367

New tools and CLI usage

• ogs --help shows the given CMake options. #2210
• Unify command line version info output. #2194
