Studio Core v. 3.24.3 changelog

Version release date: 2023-01-30

New confidence scoring

Through CONFIDENCE and IDENTIFY(template:score) syntaxes, it's now possible to declare confidence scores for extraction rules displaying the result directly on exctraction panel.

New "Tags" tab in "Classes" panel

To have a clear view of declared Tags we introduced a new panel in Classes through which automatically create a tagging rule by right clicking.

Cache the analysis results on disk

Now, it will be possible to decide whether to store the detailed log files of an analysis, for a later review, or wipe them out (keeping only the final result) to save disk space.
