## [2.7.0] - 2026-04-13
9+
10+
### Added
11+
12+
- **Host OS column** in Server Inventory for both Dashboard and Lite ([#748], [#823])
13+
- **Offline community script support** via `community/` directory for user-contributed scripts ([#814], [#822])
14+
- **MultiSubnetFailover connection option** in Dashboard and Lite for Always On availability groups ([#813], [#821])
15+
16+
### Changed
17+
18+
- **PlanAnalyzer and ShowPlanParser** synced from PerformanceStudio with latest improvements ([#816])
19+
- **MCP query tools** optimized for large databases ([#826])
20+
- **Add Server dialog UX** improved with inline connection status and full-height window
21+
- **"CPUs" renamed to "Logical CPUs"** for clarity in Lite ([#825])
22+
23+
### Fixed
24+
25+
- **Dashboard auto-refresh stalling under load** — replaced DispatcherTimer with async Task.Delay loop to prevent priority starvation during heavy chart rendering ([#833], [#834])
26+
- **Lite auto-refresh silently skipping** every tick ([#824])
27+
- **Deadlock count not resetting** between collections ([#803], [#820])
28+
- **Upgrade filter skipping patch versions** during version comparison ([#817], [#819])
29+
- **Upgrade script executing against master** instead of PerformanceMonitor database ([#828])
30+
- **Duplicate release builds** triggering on both created and published events

The installer automatically tests the connection, checks the SQL Server version (2016+ required), executes SQL scripts, downloads community dependencies, creates SQL Agent jobs, and runs initial data collection. You can also install directly from the Dashboard's Add Server dialog.
