## [2.6.0] - 2026-04-08
9+
10+
### Added
11+
12+
- **Correlated timeline lanes** on Lite Overview and Dashboard — synchronized CPU, memory, waits, and TempDB trend lanes for at-a-glance correlation ([#688])
13+
- **Dynamic baselines and anomaly detection** in Lite and Dashboard — automatic baseline calculation with anomaly highlighting on key metrics ([#692], [#693])
14+
- **Query grid comparison** — before/after comparison mode for query grids in Lite and Dashboard with global Compare dropdown ([#687])
15+
- **Nonclustered index count badge** on modification operators in plan viewer ([#788])
16+
- **Upgrade detection in Edit Server** dialog — see pending upgrades without adding a new server ([#772])
17+
- **CLI installer interactive mode** prompts for trust-cert and encryption settings ([#784])
18+
- **SignPath code signing** — release binaries are now digitally signed via the [SignPath FOSS](https://signpath.io) program
19+
20+
### Changed
21+
22+
- **PlanAnalyzer Rule 3 (Serial Plan)** comprehensively refined — severity demotion for TRIVIAL and 0ms plans, `CouldNotGenerateValidParallelPlan` treated as actionable, all 25 `NonParallelPlanReason` values now covered
23+
- **PlanAnalyzer warning rules** ported from PerformanceStudio improvements
24+
- **Text readability** — replaced all muted/dim text colors with full foreground colors for readability
25+
26+
### Fixed
27+
28+
- **Embedded resource upgrade discovery** broken — upgrades silently returned zero results for Dashboard installs ([#772])
29+
- **Archive compaction OOM** on large parquet groups
30+
- **CLI installer argument parsing** treating flags as positional args ([#786])
31+
- **Lite long-running query alerts** firing on stale DuckDB snapshots
32+
- **FinOps Enterprise feature detection** now queries all databases and filters to TDE only ([#780])
33+
- **Second launch error** — now brings existing window to foreground instead ([#769])
34+
- **Overview tab Memory Grant** showing 0 for all timestamps ([#776])
35+
- **Lite FinOps Enterprise features** query error on servers without `database_id` column ([#777])
36+
- **Collector health status** incorrect for on-load collectors
37+
- **CSV and clipboard exports** writing `System.Windows.Controls.StackPanel` as column headers instead of actual header text ([#805])
