Changelog

Release-level changes for the desktop app.

v2.0.3 - September 28, 2026

Added shared VAL_TABLE_ editing in the Editor, including table management, signal assignment, and change counts.
Added Integer, Float32, and Float64 signal data types through Vector SIG_VALTYPE_, while keeping bit length and signedness independent.

DBC saves now preserve the source encoding and original line endings for better Vector CANdb++ compatibility.
Translation output now normalizes common Unicode punctuation for CANdb++ and keeps renamed identifiers unique and within 32 characters.
Help content now follows the features enabled in the current app build.
Linux DEB packages support Ubuntu 24.04 t64 WebKit/GTK dependencies and include xdg-utils; RPM packages use improved gzip compression.
Linux installers use the CPU-only translation stack without Torch, CUDA, or Stanza.

Removed Message Type from the message editor and structured comparison because it is not stored as a separate DBC record.

Translation renames now update signal-group and relationship references, and string attribute values can be translated without changing attribute names.
Value-table edits are retained when compare data does not include the shared table catalog.
Translate and Log Analyzer progress updates no longer fail with Windows access-denied errors.
Long tables scroll without jumping, and render failures show an error screen instead of a blank window.
Saving an existing DBC now writes edited cycle time, send type, CAN FD frame format, start value, inactive value, SPN, and bus name back to their BA_ lines while preserving unrelated attributes.
Deleting a message, signal, or node now removes related comments, value descriptions, attributes, and obsolete signal-group references while preserving remaining group members.
GenSigInactiveValue now loads into the signal inactive-value field.

Added Save and Save As actions while Compare is active when either file has unsaved edits.
View, Edit, Compare, and Log Analyzer now preserve selection, filters, scroll position, and session state when switching tabs.

Compare opens with a faster text diff and builds the Structured view only when requested.
Side-by-side Compare now uses a fixed copy gutter, shared vertical scrolling, and independent horizontal scrolling.
Compare edits update locally until compare mode, whitespace settings, or saving requires a full refresh and validation.
After Compare and Save succeeds, closing the confirmation returns to Edit.

Compare and Save handles wrapped or OEM comments, apostrophes, Unicode, and embedded newlines more reliably.
German characters remain consistent between Original and Modified content.
Confirm Save tolerates pre-existing malformed comment quotes after a successful validated write.

Added an offline Log Analyzer for ASC and BLF files with DBC mapping, filters, bookmarks, plots, statistics, unknown-ID review, and multi-channel settings.
Added German-to-English and English-to-German translation for comments, value labels, value tables, and string attributes.
Added optional signal and message renaming plus an automotive glossary for technical phrasing.
Added a Models menu for installing or removing Argos language packs on demand; language packs are stored in app data and are not bundled with the installer.

Help now includes bundled release notes for offline access and can show update notes when a newer version is available.
The Log Analyzer home action now uses the same icon styling as the other home actions.

Rebuilt DBC Utility as a Tauri desktop app with a React interface and embedded Python backend.
Added production packaging for Windows NSIS and Linux DEB/RPM releases.
