+## [1.3.0] - 2026-02-20
+
+### Important
+
+- **Schema upgrade**: The `collect.memory_stats` table gains two new columns (`total_physical_memory_mb`, `committed_target_memory_mb`). The upgrade script runs automatically via the CLI/GUI installer and uses `IF NOT EXISTS` checks, so it is safe to re-run. On servers with very large `memory_stats` tables this ALTER may take a moment.
+
+### Added
+
+- Physical Memory, SQL Server Memory, and Target Memory columns in Memory Overview ([#140])
+- Current Configuration view (Server Config, Database Config, Trace Flags) in Dashboard Overview ([#143])
+- Popup column filters and right-click context menus in all drill-down history windows ([#206])
+- Consistent popup column filters across all Dashboard grids — replaced remaining TextBox-in-header filters and added filters to Trace Flags ([#200])
+- 7-day time filter option in drill-down queries ([#165])
+- Alert badge/count on sidebar Alerts button ([#109])
+- Missing poison wait defaults in wait stats picker ([#188])
+
+### Changed
+
+- Default Trace tabs moved from Resource Metrics to Overview section ([#169])
+- Trends tab shown first in Locking section ([#171])
+- Wait stats cap raised from 20 to 30 (Dashboard) / 50 (Lite) so poison waits are never dropped ([#139])
+- Settings time range dropdown now matches dashboard button options ([#210])
+- "Total Executions" label in drill-down summaries renamed to clarify meaning ([#194])
+- WAITFOR sessions excluded from long-running query alerts ([#151])
+
+### Fixed
+
+- Deadlock XML processor timezone mismatch — sp_BlitzLock returning 0 results because UTC dates were passed instead of local time
+- Sidebar alert badge not updating when alerts dismissed from server sub-tabs ([#214])
+- Sidebar alert badge not clearing on acknowledge ([#186])
+- NOC deadlock/blocking showing "just now" for stale events instead of actual timestamp ([#187])
+- NOC deadlock severity using extended events timestamp ([#170])
+- Newly added servers not appearing on Overview until app restart ([#199])
+- Double-click on column header incorrectly triggering row drill-down ([#195])
+- Squished drill-down charts — now use proportional sizing ([#166])
+- Unreliable chart tooltips — now use X-axis proximity matching ([#167])
+- Query Trace Patterns showing empty despite data existing ([#168])
+- Drill-down windows: removed inline plan XML, added time range filtering, aggregated by collection_time ([#189])
+- Row clipping in Default Trace and Current Configuration grids ([#183], [#184])
+- Numeric filter negative range parsing ([#113])
+- MCP shutdown deadlock risk ([#112])
+- Lite DBNull cast error in database_config collector on SQL 2016 Express ([#192])
+- DuckDB concurrent file access IO errors ([#164])
+
+## [1.2.0] - 2026-02-15
+
+### Added
+
+- Alert types, alerts history view, column filtering, and dismiss/hide for alerts ([#52], [#56])
+- Average ms per wait chart toggle in both apps ([#22])
+- Collection Health tab in Lite UI ([#39])
+- Collector performance diagnostics in Lite UI ([#40])
+- Hover tooltips on all Dashboard charts ([#70])
+- Minimize-to-tray setting added to Lite ([#53])
+- Persist dismissed alerts across app restarts ([#44])
+- Locale-aware date/time formatting throughout UI ([#41])
+- 24-hour format in time range picker ([#41])
+- CI pipelines for build validation, SQL install testing, and DuckDB schema tests
+- Expanded Lite database config collector to 28 sys.databases columns ([#142])
+- Parquet archive visibility and scheduled DuckDB database compaction ([#160], [#161])
+- DuckDB checkpoint optimization and collection timing accuracy
+- Installer `--reset-schedule` flag to reset collection schedule on re-install
+
+### Fixed
+
+- Deadlock charts not populating data ([#73])
+- Chart X-axis double-converting custom range to server time ([#49])
+- query_cost overflow in memory grant collector ([#47])
+- XE ring buffer query timeouts on large buffers ([#37])
+- Dashboard sub-tab badge state and DuckDB migration for dismissed column
+- Lite duplicate blocking/deadlock events from missing WHERE clause ([#61])
+- Procedure_stats_collector truncation on DDL triggers ([#69])
+- DataGrid row height increased from 25 to 28 to fix text clipping
+- Skip offline servers during Lite collection and reduce connection timeout ([#90])
+- Mutex crash on Lite app exit ([#89])
+- Permission denied errors handled gracefully in collector health ([#150])
