 It might be of interest to manually trigger a renewal of the certificates, and
 that is why the `run_certbot.sh` script is possible to run standalone at any
 time.

 # Changelog
 
+### 0.15
+- It is now possible to [manually trigger](#manualforce-renewal) a renewal of
+  certificates.
+  - It is also possible to include "force" to add `--force-renewal` to the
+    request.
+- The "clean exit" trap now handle that parent container changed to
+  [`SIGQUIT`][15] as stop signal.
+- The "certbot" server block (in Nginx) now prints to stdout by default.
+- Massive refactoring of both code and files:
+  - Our "start **command**" file is now called `start_nginx_certbot.sh` instead
+    of `entrypoint.sh`.
+  - Both `create_dhparams.sh` and `run_certbot.sh` can now be run by themselves
+    inside the container.
+  - I have added `set -e` in most of the files so the program exit as intended
+    when unexpected errors occurs.
+  - Added `{}` and `""` around most of the bash variables.
+  - Change some log messages and where they appear.
+- Our `/scripts/startup/` folder has been removed.
+  - The parent container will run any `*.sh` file found inside the
+    [`/docker-entryoint.d/`][16] folder.
+
 ### 0.14
 - Made so that the container now exits gracefully and reports the correct exit
   code.
