What the current release covers
Less copy, same answer: what DBC Utility actually does.
The public docs and release notes point to one focused workflow: inspect the database, edit with context, compare revisions, and validate before save.
Browse
Read the file structure fast
Inspect messages, signals, comments, frame IDs, and file metadata in one desktop view.
Edit
Update definitions with context
Work with message and signal fields, value tables, receivers, and mux-related fields.
Compare
Review changes in three modes
Switch between side-by-side, unified, and structured comparison views.
Multiplexer
Treat mux-heavy files as first-class
Use multiplexer-aware filtering, editing, and validation instead of manual workarounds.
Layout
Check CAN and CAN FD packing visually
Inspect message layouts at the bit level before saving or releasing a change.
Access
Get back to active work quickly
Use the home screen, recent files, and search across messages, signals, or frame IDs.
Workflow
Built for review before release.
The current workflow stays compact: open, inspect or edit, compare, then validate before writing changes out.
Open from the home screen or recent files
Start faster without rebuilding the same path every time.
Inspect or edit with signal and mux context
Keep structure, field details, and editing workflows close together.
Compare revisions and verify layout before save
Use diff review and bit-level layout checks before a change moves forward.
