+# Tutorial: Hot Reload
+#
+# Membrane watches your YAML file and reloads the configuration automatically
+# whenever you save a change. No restart needed.
+#
+# 1.) Start Membrane:
+#    Linux/Mac:
+#      ./membrane.sh -c 05-Hot-Reload.yaml
+#    Windows:
+#      membrane.cmd -c 05-Hot-Reload.yaml
+#
+# 2.) Call the API:
+#
+#      curl http://localhost:2000
+#
+#    You should see a list of public APIs from api.predic8.de.
+#
+# 3.) While Membrane is still running, open this file in a text editor.
+#    Change the url below from https://api.predic8.de to https://httpbin.org
+#    and save the file.
+#    The console shows "Configuration Changed" within a second.
+#
+# 4.) Call the API again:
+#
+#      curl http://localhost:2000
+#
+#    The response now comes from httpbin.org. No restart was needed.
+#
+# 5.) Stop Membrane:
+#    Press Ctrl+C in the terminal.

 ## Membrane 8.0.0 (Java 25)
 
+- Log harmonization:
+  - Decide if log message start with uppercase or lowercase.
+     - e.g.:  Error loading log configuration., Started 1 API:, Closing server port:, listening at '*:2000'
 - Upgrade baseline to Java 25
   - Bump `javac.source`/`javac.target` from 21 to 25 in the root pom.xml
   - Simplify `Util.createNewThreadPool()`: the reflective lookup of `Executors.newVirtualThreadPerTaskExecutor` and the `--enable-preview` handling are leftovers from the Java 19/20 preview era; call it directly and drop the `-Dmembrane.virtualthreads` fallback (or keep the flag as a plain if).
