Fixed Issues in ThingWorx C SDK 3.1.0
The following table describes the issues fixed in this release:
Tracking Number
Fixed an issue where twMap_put returns an integer success code.
Now, twMap_put returns a pointer to the previous entry at the given key, and the user can free up the memory associated with that previous entry. The function returns NULL if the key was not already in use.
Fixed an issue with error messages being displayed about non-existent directories when building Edge C SDK.
Fixed an issue where twFileManager_SendFile times out before File Transfer times out.
Fixed an issue where TW_NOTHING type length is not consistent.
Fixed an issue with the readProperties() function.
Fixed an issue where C SDK was not able to bind Things with names greater than 127 characters.
Fixed an issue where twApi_SetSubscribedPropertyVTQ from C SDK does not update property value on Platform with TW_PUSH_TYPE_ALWAYS.
Fixed potential security issues, including items proactively identified by the vulnerability scanning software or PTC Quality Assurance testing. Make sure to upgrade as soon as possible to take advantage of these important improvements.
