+## [2.6.0] - 2026-04-08
+
+### Added
+
+- **Correlated timeline lanes** on Lite Overview and Dashboard — synchronized CPU, memory, waits, and TempDB trend lanes for at-a-glance correlation ([#688])
+- **Dynamic baselines and anomaly detection** in Lite and Dashboard — automatic baseline calculation with anomaly highlighting on key metrics ([#692], [#693])
+- **Query grid comparison** — before/after comparison mode for query grids in Lite and Dashboard with global Compare dropdown ([#687])
+- **Nonclustered index count badge** on modification operators in plan viewer ([#788])
+- **Upgrade detection in Edit Server** dialog — see pending upgrades without adding a new server ([#772])
+- **CLI installer interactive mode** prompts for trust-cert and encryption settings ([#784])
+- **SignPath code signing** — release binaries are now digitally signed via the [SignPath FOSS](https://signpath.io) program
+
+### Changed
+
+- **PlanAnalyzer Rule 3 (Serial Plan)** comprehensively refined — severity demotion for TRIVIAL and 0ms plans, `CouldNotGenerateValidParallelPlan` treated as actionable, all 25 `NonParallelPlanReason` values now covered
+- **PlanAnalyzer warning rules** ported from PerformanceStudio improvements
+- **Text readability** — replaced all muted/dim text colors with full foreground colors for readability
+
+### Fixed
+
+- **Embedded resource upgrade discovery** broken — upgrades silently returned zero results for Dashboard installs ([#772])
+- **Archive compaction OOM** on large parquet groups
+- **CLI installer argument parsing** treating flags as positional args ([#786])
+- **Lite long-running query alerts** firing on stale DuckDB snapshots
+- **FinOps Enterprise feature detection** now queries all databases and filters to TDE only ([#780])
+- **Second launch error** — now brings existing window to foreground instead ([#769])
+- **Overview tab Memory Grant** showing 0 for all timestamps ([#776])
+- **Lite FinOps Enterprise features** query error on servers without `database_id` column ([#777])
+- **Collector health status** incorrect for on-load collectors
+- **CSV and clipboard exports** writing `System.Windows.Controls.StackPanel` as column headers instead of actual header text ([#805])
