Hi,
The objective of removing the older software version from the web are two:
1) To ensure that our customers have access to the most secure software (This is from a network security point of view).
2) To encourage customers to choose newer releases which have the latest functional and security upgrades.
This does not correspond or have any relationship with our devices discontinuance. The device discontinuance is handled differently based on a separate criteria. For more information on this, it is best to contact your Sales representative where you are purchasing the devices from.
What we do here also does not have any relationship with trying to saving space for the files as well. The move is driven by the 2 reasons mentioned above.
To answer your questions:
1) Lite/Web/Free/Standard 13.0 SP1 or 13.1.4 versions will be available for download.
2) If you are using the 13.0 and older versions, you may continue to use this software version BUT you will not receive any support should you encounter any issues. Any issues support will require 13.0 SP1/13.1.4 or newer versions.
We are very happy with your support all these years and we look forward to have your support going forward. Let me know if you have further questions. Thanks.
