[ZhuchkaTriplesix]

CHANGELOG [Unreleased]: what has been merged to dev since the last update (ca849cd, 2026-10-10), 119 commits.

• Added → UI kit: the control scale and the button family (epic(ui): buttons in the Querya UI kit: one control scale, our own button family, no shadcn buttons #1331–feat(ui): QueryaSplitButton, QueryaMenuButton and QueryaDialogActions #1335, refactor(ui): migrate toolbars, panels and the self-made buttons to QueryaButton #1337, refactor(ui): migrate dialogs and forms to QueryaButton and QueryaDialogActions #1338), own toast and text styles (epic(ui): remove shadcn_flutter from the app #1465).
• Changed: dialog footers on QueryaDialogActions, one height per toolbar row, the ERD view split into parts (refactor(erd): decompose 2900-line ErdView into pure ErdLayoutEngine, ErdCanvas, ErdTableCard and ErdMinimap #1362), the SQL toolbar / connection forms / highlighter lifecycle, QueryaApp.build without side effects.
• Fixed: removing a connection, SQL workspace status and error display, editor and data grid fixes, startup recovery screen, Windows updater mirror, SSH tunnel leaks, PostgreSQL SSL mode dropdown, packaging, accessibility.
• Security (new section): PostgreSQL TLS (verify-full with a root CA), extension sandbox credential exfiltration.
• Performance: result grid (perf(grid): hoist secondary click (context menu) and tooltip handling from _GridCell to grid level #1346, perf(grid): offload GridFilterEngine to background isolate and debounce in ResultsTab #1347), editor (perf(editor): eliminate quadratic line counting and substring allocations in SqlStatementSplitter #1350–perf(editor): eliminate two-way controller bouncing and full-string comparisons in QueryaCodeEditor #1352), drivers (perf(database): integrate CompactResultDataset into SQL drivers to eliminate 3x memory copies and string allocations #1355) and UI items.
• Testing: the new guards.

Only items merged to dev are listed. Not in it yet: #1472 (ERD export flows), and the Gap / colour-type steps of #1465. The existing Performance bullets for #1168–#1172 were left as they were; those issues are still open, so that wording is worth a check before the release.
