+### Version from `compile_version_string.txt` (2026-10-07)
+
+- **Problem:** `qt6`'s `CMakeLists.txt` had the version hard-coded as 5.7.4. The qmake build
+  read it from `build_scripts/compile_version_string.txt` (`5.8.17-release`). `master` is
+  fully merged into `qt6`, so only the number was stale. Consequence: the version check
+  (comparison with `ver/versioncheck.json`, 5.8.17) would have reported an update.
+- **Fix:** CMake reads the file.
+  - `APPLICATION_VERSION` = full string, as in qmake.
+  - `project(VERSION)` = numeric part.
+- **Result:** `APPLICATION_VERSION="5.8.17-release"`, `CMAKE_PROJECT_VERSION=5.8.17`, package
+  `dist/AdvancedSettings-5.8.17-linux-arm64.tar.gz` (3.0 MB).
