+* **(Custom Enrichment)** On-prem administrators can now configure custom URLs for EPSS and KEV enrichment data sources under **Settings → Finding Enrichment Settings**. Each source (EPSS scores and CISA Known Exploited Vulnerabilities) can be independently enabled and pointed to an internal mirror or proxy. A **Test Configuration** button validates connectivity before saving. Findings with CVE IDs are automatically enriched with EPSS score/percentile and KEV status during enrichment runs.
+* **(Performance)** Optimized API response times across all endpoints with selective field loading and conditional prefetches.
+* **(Performance)** Improved Dashboard load times by eliminating redundant authorization queries and caching license lookups.
+* **(Performance)** Improved deduplication performance by batching duplicate marking and deferring large text fields.
+* **(Performance)** Improved false-positive history processing performance during async imports by using batch operations.
+* **(Pro UI)** Asset hierarchy filter dropdowns now only show relevant options (e.g., Parent filter shows only assets that have children).
+* **(Security)** Hardened container configurations for improved runtime security.
+* **(Universal Parser)** Added a list view and field mappings modal to the Pro UI for managing Universal Parser configurations.
+* **(Universal Parser)** Added support for 7 new fields: `file_path`, `component_name`, `component_version`, `line`, `steps_to_reproduce`, `severity_justification`, and CVSSv4 vectors.
