Horner have released the much publicised CScape 9.9 SP3
This service pack is primarily aimed at the Advanced Relay logic programming environment with enhancements such as UDFBs, Gmail support for emails, downloadable protocol enable/disable, DHCP and DNS support, MQTT Sparkplug IOT support.
Some of these additional functions will require a firmware update which is also available for all processors.
Should you upgrade?
If you have a program that works and does not reuire the additional enhancements, then leave it alone.
If you are starting a new project and the enhancements are of value to you, or if you are using one of the newer processors, then you should upgrade.
NOTE: while Horner endeavour to keep as much upwards compatbility as possible, there can be changes in some established functions in new versions of CScape that may require tweaks in the code. Avoid upgrading the CScape version of code that is running in the field without fully testing it first.
You can have multiple copies of CScape on a single machine provided that they are installed in their own directory.
