Protocols, Smart Polling, and Arc

A list of the improvements for Protocols, Smart Polling and Arc that have been introduced in this release.

Improved ABB 800xA Asset identification using the MMS protocol. Introduced a new "SIGN:INFORMATION-GATHERING" alert type, used to cover a use case of a log transfer from ABB 800xA controllers.
Introduced XMPP protocol tagging.
Introduced CoAP protocol tagging.
Improvements to the passive support for MELSEC, SLMP and MELSOFT protocols.
Improved parsing robustness of asset information gathered by WinRM Smart Polling strategy.
It's now possible to exclude arbitrary nodes from Smart Polling plans.
As announced previously, the deprecated value field of the node_points query source is removed, in favor of the content field. Upon upgrade, the data in that column is deleted. A rollback after the installation will not regenerate this data. We recommend that our customers adapt their queries, assertions and reports to use the content field instead of value.
