-    ESLint nitpicks in the `lti` module (#5830)
+    Update ESLint (#5831)
 
-    Looking at updating ESLint across the board, I found a few small things
-    in the `lti` package.
+    ESLint >= 9 brings a few breaking changes, making the dependabot PRs
+    that try to update it fail; cf. #5824, #5819, #5813, #5812.
 
-    * Formatting was werid.
-    * There was unused ESLint configuration in `package.json`.
+    The main thing was a change in the default configuration format. There
+    is a compatibility flag, but I don't think we want to use it, since the
+    old way is also deprecated now. See also
+    https://eslint.org/docs/latest/use/migrate-to-9.0.0#-new-default-config-format-eslintconfigjs.
+
+    Without that, updating basically entailed the following:
+
+    * The shared config in `docs/checkstyle` was converted to the new
+    format,making it a full `npm`-package in the process.
+    * This is required because of the way the new format handles plugins and
+    other dependencies.
+    * Note that this also makes the `resolve-plugins-relative-to` option
+    obsolete, which is good since it is no longer supported. This patch
+    removes it everywhere we used it.
+    * I also added a dependabot rule to keep that package's few dependencies
+    up to date.
+    * The `--config` option can't load such shared configs, though, so all
+    the packages that use this combination got a new config of their own,
+    basically deferring to that package.
+    * Modules which already had their own config file had it updated as
+    well.
+    * `.eslintignore` is no longer supported and thus got moved to the new
+    config file(s).
+    * I also removed some unnecessary `eslint-disable` comments.
+
+    The `eslint-plugin-header` is no longer compatible with ESLint 9. I
+    replaced it with `eslint-plugin-headers`, but that required kind of an
+    ugly hack. See also
+    https://github.com/robmisasi/eslint-plugin-headers/issues/4.
+
+    Note that this udpate might slightly change the linting rules; I did not
+    check every last change to default rules and options! The one thing I
+    hade to change was to add a setting to the `no-unused-vars`-rule,
+    because the corresponding default changed, and we depend on the old
+    default. See also
+    https://eslint.org/docs/latest/use/migrate-to-9.0.0#-no-unused-vars-now-defaults-caughterrors-to-all.
+
+    Note also that the `lti`-module also uses ESLint, but as part of it
+    being a `create-react-app`, so we don't control the ESLint version in
+    there. I didn't touch that module. (Well, in this PR; see #5830.) We
+    might want to change that in the future, though, since CRA is deprecated
+    in itself.
+
+    Another thing we might want to change in the future is the
+    `engage-paella-player-7`-module using the deprecated
+    `@babel/eslint-parser`.
+
+    We also use a few deprecated ESLint rules, but for now I wanted to
+    chagne the configs as little as possible, since the necessary changes
+    are already quite sweeping. I might make a follow-up PR in the coming
+    days.
