 - Add line-based code coverage reports into CI pipeline. Coverage reports are generated by `coverage.R` (PR #262, 10cac49d005e87c3964cc61711e7f5acef749626, b3b9f4ac7a9911bd00293c68fac88e0f9033bdfb, c815d18dc6266d620a7a145493417b87ac08679e, e8093525fdaf46e54f2f7fcc6358ca7892e795e5, 32d04823e2007c63d2a43ce59bea3057327c19a7)
 - Add the possibility to split data time-based by multiple data sources (PR #261, 1088395f46b84028c8d7c463ca86b5dc38500c26, e1f79fc9e40cd6f41c946be42db364b2101cfe10, 0bb187fec0fd801d7634bf8d5180525770f6ab0b, 371a97ac6ebf3de4fe9360dea79d62e2ed3ef585)
+- Add tests for uncovered functionality in `util-misc.R` and `util-networks.R` (PR #264, ff30f3238b1bf2539280d0d055a5d925c197c271, af80551d0615a49b86e45ff596bd75941ee88f91)
 
 ### Changed/Improved
 
+- Deprecate support for R 3.6 (PR #264, c8e6f45111e487fadbe7f0a13c7595eb23f3af6e, fb3f5474259d4a88f4ff545691cca9d1ccde90e3)
+- Replace deprecated `igraph` functions by their preferred alternatives (PR #264, 0df9d5bf6bafbb5d440f4c47db4ec901cf11f037)
+- Change the default value for the `issues.from.source` configuration parameter from `JIRA` and `github` to `github`. This change is motivated by the fact that, in practice, `github` is the predominant source for issue data (PR #264, 5ff83c364f6bfc1e6ff95e9c5f1087e031c48a5d, 8c8080cb9caf115f19d9f145ad6e6c108b131a67, 8bcbc81db521877908d2e5c2989082ed672f2a3b)
