+# Original espota.py by Ivan Grokhotkov:
+# https://gist.github.com/igrr/d35ab8446922179dc58c
+#
+# Modified since 2015-09-18 from Pascal Gollor (https://github.com/pgollor)
+# Modified since 2015-11-09 from Hristo Gochkov (https://github.com/me-no-dev)
+# Modified since 2016-01-03 from Matthew O'Gorman (https://githumb.com/mogorman)
+#
+# This script will push an OTA update to the ESP
+# use it like:
+# python espota.py -i <ESP_IP_addr> -I <Host_IP_addr> -p <ESP_port> -P <Host_port> [-a password] -f <sketch.bin>
+# Or to upload SPIFFS image:
+# python espota.py -i <ESP_IP_addr> -I <Host_IP_addr> -p <ESP_port> -P <HOST_port> [-a password] -s -f <spiffs.bin>
+#
+# Changes
+# 2015-09-18:
+# - Add option parser.
+# - Add logging.
+# - Send command to controller to differ between flashing and transmitting SPIFFS image.
+#
+# Changes
+# 2015-11-09:
+# - Added digest authentication
+# - Enhanced error tracking and reporting
+#
+# Changes
+# 2016-01-03:
+# - Added more options to parser.
+#
+# Changes
+# 2023-05-22:
+# - Replaced the deprecated optparse module with argparse.
+# - Adjusted the code style to conform to PEP 8 guidelines.
+# - Used with statement for file handling to ensure proper resource cleanup.
+# - Incorporated exception handling to catch and handle potential errors.
+# - Made variable names more descriptive for better readability.
+# - Introduced constants for better code maintainability.
