-  * PLEASE SUMMARIZE remaining Apertis changes
+  * Sync updates from debian/bookworm-security
+  * Remaining Apertis specific changes:
+    - d/rules: Set DIST to apertis and add apertis to the list of
+      distributions where firefox bundled libraries should be used.
+    - d/rules: Set SHELL variable as docker doesn't carry this environment
+      variable.
+    - d/control.in: Drop the test for !bullseye because, for Apertis, there
+      are multiple distributions based on Bullseye.
+    - Disable WASM Sandboxed Libraries because we don't have the development
+      package in the version of LLVM in Apertis.
