-  * Placeholder entry. The real version and target series are set at upload
-    time by debian/rules consumers: the release workflow rewrites this with
-    `dch` per series, and the Launchpad nightly recipe derives the version
-    from its `deb-version` template. See pkg/ppa/README.md.
+  * Placeholder entry, except for the version above. Releases rewrite this file
+    with `dch` per series in publish-ppa.yaml, but the Launchpad nightly recipe
+    reads that version through `{debupstream}` and appends `-0~{revtime}`. It
+    must name the next, unreleased version, so a nightly sorts above the last
+    release and below the next one. Keep it in step with CMakeLists.txt;
+    chore-version-bump.yaml does that on release. See pkg/ppa/README.md.
