Changelog

3.8

Fusion in Fabric General Availability: Fusion in Fabric is moving to GA, and existing customers can now migrate existing data from ADX to a Fabric Eventhouse. See Migration Instructions for detailed migration instructions.

Enhancements

SFFH-2330 - Outage handler improvements: Updated outage processing to take advantage of 3.6 deduplication behavior, reducing local disk usage and avoiding scenarios where outage processing consumed excessive disk space.

SFFH-2419 - Gap fill requests: Added support for gap-fill style requests so historical data can be requested for selected tags and time ranges, then merged into ADX ingestion flow to backfill missing data.

Bug Fixes

SFFH-1750 - Model Reader soft-link handling: Fixed PI model traversal so soft links do not cause missing child entries by following only strong/composition parent-child references.

SFFH-2129 - Model Reader OPC processing: Addressed a model update failure where parent-child records could be processed in the wrong order while reading OPC models.

SFFH-2437 - Migration tool error handling: Resolved a migration failure scenario where the ADX migration process could stop unexpectedly with policy-related bad request errors.

SFFH-2724 - Large Tag Controller DB upgrade reliability: Improved upgrade behavior for larger Tag Controller databases where upgrades from 3.6 to 3.6 SP1 could fail and prevent function startup.

SFFH-2587 - ADX runner retry behavior: Updated retry logic so throttled ADX commands are handled more safely instead of immediate aggressive retries.

SFFH-2035 - GetLinearInterpolate multi-tag fix: Corrected interpolation logic so first/last real values are evaluated per time series when multiple tags are queried.
