+# 1.3.21:   Bug fixes found during testing:
+#           Fix directory of ATBUpdateTool.ini to be the working directory of
+#           the application rather than just ".".
+#           Check existance of etc-directory inside customer repository.
+#           Check for valid ISMAS trigger (button) 15x (=90s).
+#           NOTE: if the customer repository is cloned (or repaired and cloned
+#           again), and if the settings always-download-config=true and
+#           always-download-dc=true in the ATBUpdateTool.ini file, the download
+#           the printer-json files and the device controller file, even without
+#           an activated ISMAS trigger (button). The tariff-files are rsynced to
+#           the local filesystem for such clone.
+#           Set new filename for device controller: dc2c.bin.
