+# QElectroTech - CHANGELOG
+
+## Version 0.100
+
+_Compiled from provided commit logs and contributor notes._
+
+## Overview
+
+This release (v0.100) collects a large set of new features, UI and editor improvements, element and symbol updates, build and packaging fixes, dependency upgrades, translations, and a broad set of bug fixes and stability improvements. It is intended as a stable, feature-rich stepping stone toward the next major workflows for symbol editing, terminal/strip handling and export improvements.
+
+## Highlights / Key Features
+
+- **Terminal Strip / Terminal Strip Editor**
+- New TerminalStripItem type and related editor workflow added.
+- Support for drawing and displaying terminal bridges and links in the editor.
+- Full editor support (layout preview, save/load into .qet files) and undo support for terminal strip operations.
+- **New Example Projects**
+- Several new example projects included, notably photovoltaic (PV) examples to help users getting started with PV designs.
+- **Improved Export / Print Handling**
+- Export limits adjusted and better handling of QPainter/printing boundaries to avoid export artefacts and out-of-range errors.
+- Export dialog updated to allow larger pixel limits where appropriate.
+- **Element & Symbol Additions**
+- New elements and symbols added (including vendor-specific elements and additional sensors/Arduino components).
+- Improvements to element import & metadata handling.
+- **Packaging & Multi-arch Support**
+- Updated packaging scripts for AppImage, Flatpak, Snap and macOS deployment. Improved aarch64/arm64 support.
+
+## Detailed Changes
+
+### Editor & UX
+
+- Better handling for **rotation, flip and mirror** operations in the element editor:
+- Primitives and text rotation behavior improved.
+- Finer rotation increments and predictable text orientation after flips/rotations.
+- **Wiring and conductor behavior**:
+- More robust creation and movement of wires and conductor bundles.
+- Improved text attachment and positioning for wires and improved stability while editing complex conductor networks.
+- **TerminalStrip editor**: see Highlights - includes drawing, preview, layout editing, persistent storage in the project file and undo support.
+- **Element Editor & Symbol Trim/Sort**:
+- Improved trimming/normalization of element metadata.
+- Better sorting and error handling for element imports (DXF and other formats).
+- Small UI improvements: About dialog updates, autosave spinbox ranges, improved tooltips and mouse-hover help for dynamic texts.
+
+### New & Updated Elements
+
+- New elements added for industrial and automation workflows (including Siemens-related elements, logic elements, sensors and Arduino components).
+- Symbol library additions and cleanup; improved defaults for newly added symbols.
+- Element meta-data cleanup: article numbers, descriptions, and manufacturer fields were normalized and trimmed on import.
+
+### Export / Printing / PDF
+
+- Adjusted internal export limits to avoid hitting QPainter size restrictions; users can now export larger, high-resolution images/prints in more cases.
+- Better handling of page sizes and printer-related geometry using QRectF improvements.
+- PDF export improvements to increase reliability of exported vector content.
+
+### Build, Dependencies, Packaging
+
+- Upgrades of core test and build dependencies:
+- Catch2 upgraded to v2.13.10.
+- googletest upgraded to v1.17.0.
+- CMake fixes and i18n handling corrected for nl_BE and other locales.
+- Packaging scripts updated across platforms (AppImage/Flatpak/Snap/macOS deploy) including fixes for aarch64/arm64.
+- Submodule updates (e.g., qelectrotech-elements, pugixml, SingleApplication) synchronized where needed.
+
+### Internationalization & Translations
+
+- Large translation updates across many languages: German (DE), French (FR), Dutch (NL, including nl_BE), Swedish (SV), Italian (IT), Polish (PL), Portuguese-BR (PT-BR), Serbian (SR), Chinese (Simplified) and others.
+- Fixes and corrections for many UI strings and localized resources.
+
+### Tests, QA & Logging
+
+- Improved logging and machine/config-path reporting; Git revision display refined to only show a revision when available.
+- Unit test updates and fixes to align with updated testing frameworks.
+
+## Bug Fixes (selected)
+
+- Fixed crashes and various null pointer access issues discovered by static and dynamic testing.
+- Resolved multiple reported bugs that caused build failures on some platforms (FTBFS fixes for macOS and others).
+- Fixed issues with automatic conductor/strand numbering in several edge cases (referenced Bug 293 in the commit logs).
+- Resolved text/summary headline issues in the German-language summary generator.
+- Fixes for a number of visually incorrect renderings and layout corner-cases during element transformation (rotate/flip/mirror).
+- Fixed issues that affected export sizes and caused export artifacts (referenced fixes for bug IDs around #329/#330 in commit notes).
+
+## Developer & Contributor Notes
+
+- Reworked parts of the codebase to use QRectF consistently for better compatibility with QPrinter and export pipelines.
+- Code-style cleanups and comment improvements applied throughout the project.
+- Expanded test coverage and dependency refresh to keep CI builds stable.
+

+
+## Upgrade / Migration Notes
+
+- No database or project file format breaking changes were reported in the provided logs. As always, back up projects before opening them with a new version.
+- If you rely on custom element libraries or third-party submodules, verify submodule synchronization after upgrading.
+- If you are using custom packaging pipelines, review the updated packaging scripts for any changes required by new dependency versions, especially on aarch64/arm64.
+
+## Known Issues & Limitations
+
+- Some very large exports may still be limited by platform-specific rendering restrictions; the export dialog now allows larger pixel limits but extreme sizes may still hit system-level limits.
+- If you use niche element-import workflows (DXF → element import), occasionally metadata normalization may alter whitespace/trim rules - verify newly imported elements in the element editor.
+
+## How to get help / report bugs
+
+- Use the project issue tracker (see repository) to report regressions or new bugs with detailed reproduction steps and example .qet files where possible.
+- Include the output of Help → About (application version and Git revision) when reporting build/packaging issues.
