+# QElectroTech — Release notes: 0.100 → current master (0.200.1-dev)
+
+*Covers the period 26 January 2026 – 9 October 2026: 2,253 commits and 669 merged pull requests. Numbers in brackets are GitHub PRs (#nnn) or bug tracker entries (bugtracker #nnn).*

+
+## Highlights
+
+- **Qt 6 is now the platform.** The Qt 6 migration is complete, Qt 5 support has been removed, and Windows, macOS, Flatpak and Snap packages are built on Qt 6 / KF6.
+- **Rewritten auto-numbering.** Renumbering of existing elements, new numbering parts (alphabetic, cyclic/modulo, zero-padded formats), undo/redo for counters, global rules in the settings, and importing rules from another project.
+- **Many more drawing and editing tools.** Editable resize/rotate/skew handles for shapes and pictures, an Arc tool and a fillet tool, Group/Ungroup, Align and Snap to grid, mirroring symbols, rotating groups, text-box width handles, and dropping pictures onto a sheet.
+- **Productivity UI.** Command search, Ctrl+G jump to element or cell, an element picker and shortcut bar at the cursor, a context command bar, mouse gestures, repeat-last-command, configurable shortcuts, toolbars and gestures (Customise window), and paste under the cursor.
+- **Wiring, BOM and PLC.** A from-to wiring list export, a PLC Manager, slave contact groups and a full contact comb, terminal potential grouping, a material list lookup, smart-device BOM metadata, a generic device wizard, and drag and drop onto terminal strips.
+- **Import and export.** EPLAN Data Portal (.edz) import, PDF page import, and much better DXF export (layers, symbols as blocks with attributes). PDF export gains clickable cross-reference links and can be made reproducible.
+- **Command line, scripting and AI assistants.** Headless export and verification from the command line, a JavaScript scripting API (off by default), script buttons and a script manager, a macro recorder, and an MCP server (`qet-mcp`) with a "live mode" so an AI assistant can work on an open project.
+- **Dark themes and icons.** All toolbar and menu icons are now SVG, there are "qet" and "qet-dark" icon themes, an optional dark folio canvas, and many dark-theme fixes.
+- **English is the source language.** The interface text is now written in English (previously French), "folio" is renamed "sheet" in the English UI, and Korean has been added as a new language.
+- **Stability.** A large number of crash, use-after-free and memory-leak fixes, rotating crash-recovery snapshots, a hardened crash reporter, diagnostic logging, and reproducible project saving.

+## Bug fixes (selection)
+
+### Crashes and memory safety
+- Use-after-free and teardown crashes: backup threads [#512], restore of backups [#711, #1031], project/diagram teardown [#789], IPC file forwarding [#868], the terminal strip dock [#1162], closing without saving [#1231], and the template editor [#1407]
+- Crashes when opening a project without a sheet [#797], with an unlinked contact [#1234], or with invalid corner layout [#670]
+- Element editor zoom crash [#799]; huge symbol sizes [#1232]; NaN and infinite coordinates rejected on load [#792, #996, #1161, #1194]

+- Thread-safety fixes for data paths and the elements panel [#514, #1163]
+
+### Saving, loading and file format
+- Saving is now reproducible: deterministic element, conductor, title block and XML ordering, and a second save changes nothing [#779, #814, #844, #846, #1030, #1109]
+- QDom serialization hardened against invalid data (CVE-2026-15037) [#568]

+- Older parts lists keep their rows [#1077]; legacy sequential attributes are read correctly [#1385, #1386]
+- Wires no longer move to another symbol after saving an older project [#1417]; replacing a symbol keeps its wires [#1116]
+- Text position stays stable after a font-size change [#501]; wire text rotation is preserved [#707]
+
+### Editing and the diagram editor
+- Several copy/paste fixes: broken conductors, alignment, PLC data, master/slave links and underscore labels [#746, #770, #899, #909, #910, #911, #982, #997, #1188]
+- Undo stack fixes [#925, #1039, #1192]; group rotation [#921]; the first click in the element editor no longer moves elements [#520]
+- Junction dots on wide conductors and on shared lines [#862, #1299]; straight wires drawn diagonally [#1127]; unnecessary bridge routing [#890]
+- Duplicating sheets renews UUIDs and keeps text positions [#477, #544, #856, #895]
+- Multi-line symbol text alignment [#1155, #1160, #1176, #1302, #1357]
+- Cross-reference overlap and positioning fixes [#712, #1263, #1287]
+
+### Title blocks, reports and BOM
+- Title block variables: empty page-level overrides, bare %name variables, unset variables, names with a slash, and file names cut at the first dot [#572, #717, #719, #725, #989, #1121, #1140]
+- The summary table is ordered by sheet [#864]; custom summary SQL is kept [#887]; queries return all their rows [#1066] and are capped [#985]
+- Terminal and contact blocks appear in the parts list [#849]; the wire-name export no longer double-counts [#724]
+- Sheet dates are correct in the project database [#1134]; the database is rebuilt only once per load [#840]
+
+### UI, theming and platform
+- Dark theme: element icons [#620, #695, #744, #1092], slave cross-references [#718], the search field, and imported image colours [#1349]
+- Locale and translation loading: regional locales, the lang/ path, double-click on Windows, and an English fallback [#496, #498, #559]
+- Windows: Unicode and long paths in collections [#524, #1243, #1244], file association without admin rights [#1149], and MS Shell Dlg fonts in PDF [#1012, #1029]
+- macOS: bundle identifier and file dialogs [#829], Fusion dark palette [#894], properties dialog placement [#715], file-open events, arm64 bundle on Sequoia, and the black screen after PDF export
+- Snap: libxcb-cursor crash on Ubuntu 24.04 [#517]
+- Recent files menu updates during the session [#863]; cancelling the potential selector [#584]; dock layout restored on Qt 6 [#769]
+
+### Performance
+- Fixed the Qt 6 load-time regression in XmlElementCollection [#570]; removed the pugixml pass from ElementFactory [#567]
+- Faster saving of projects with pictures [#1067]; the element style regex is compiled once [#841]; picture cache fixes [#842]
+
+---
+
+## Translations
+- **New language: Korean** [#419–#431]
+- **English is now the source language** of the interface [#1390]; "folio" is renamed "sheet" in the English UI [#1216]; hundreds of untranslated or broken English strings are fixed [#1124, #1261, #1389]

+- **Packaging:** Flatpak and Snap moved to Qt 6/KF6 (Flatpak runtime 6.11, Snap core24); the macOS arm64 bundle uses CMake; the NSIS installer is on 3.x with fonts and more installer languages; `publiccode.yml` added
