CANcorder Version History

Version 1.3.843

Released 2026-09-27

Added

• English and German PDF manuals ship with the app and open directly from Help, including offline.
• A product introduction, linked contents, chapter bookmarks, and printable A4 layout make the manuals useful before purchase and at the workbench.

Changed

• In-app help and PDF manuals now use the same chapter sources, with readable tables and improved German text.
• Manual covers show Dr. Lauer IT and the CANcorder logo. Manuals are generated for each package build.

Distribution

• Signed and notarized Universal macOS release for Intel and Apple Silicon. The public Windows installer remains at 1.2.293.

Version 1.3.841

Released 2026-09-27

Added

• Export Messages or Transport logs as searchable PDF reports, with current filters or all records, embedded fonts, complete payloads, continuation pages, and English or German report labels.
• PDF reports include per-ECU response times, jitter, and P95, with documented timing exclusions and a stable snapshot while capture continues.
• Reload externally edited log files while preserving filters.
• Native macOS K-Line capture through OpenPort 2.0, readable text-log export, and ASCII payload search.

Fixed

• Long PDF payloads use the remaining page space; KWP TransferData replies contribute correctly to response-time statistics.
• Kept native USB adapter discovery compatible with macOS 11.
• Fixed the PDF product link and completed German response-time labels.
• Fixed stale macOS drag-and-drop paths and reconnecting CAN adapter linking.
• Suppressed native CAN adapter self-echoes and hid CAN FD settings for classic-only adapters.
• Update checks now support separate platform versions and Universal macOS downloads.
• Fixed HSFZ and DoIP capture import silently dropping diagnostic messages that span multiple TCP segments, so large multi-frame requests such as flash TransferData now appear instead of going missing.
• Fixed faint leftover "ghost" text appearing behind rows in the Transport and Frame tables while scrolling.
• Fixed number formatting so byte sizes and counters follow the selected interface language (for example, German now shows 1.441.280 instead of 1,441,280).
• Fixed SAE TP2.0 reassembly fabricating a spurious message when a data frame was lost or arrived out of order.
• Fixed long J1939 BAM transfers being discarded mid-transfer when packets were paced slower than the reassembly timeout allowed.
• Fixed valid single-byte-header K-Line frames being dropped instead of decoded.
• Fixed CAN FD frames being discarded when importing candump logs: lines using the ## flags notation were counted as unreadable instead of decoded, so traces written by ECUmulator++ lost exactly the frames they marked as FD.

Distribution

• This release is for macOS, with a signed and notarized Universal app for Intel and Apple Silicon. The public Windows installer remains at 1.2.293.
• Download this macOS release from the product page. Older clients use a shared update version, which stays at 1.2.293 until Windows catches up; this prevents false Windows update prompts.

Version 1.2.471

Released 2026-05-12

Fixes And Reliability

• Fixed SAE TP2.0/KWP TransferData decoding and binary export so the first payload byte is preserved.
• Expanded transport messages now show the complete payload instead of only the first eight lines.
• Fixed candump log import for devices recording negative timestamps before their clock was set.

Version 1.2.293

Released 2026-04-22

Fixes And Reliability

• Fixed Windows UI unresponsiveness during high-rate CAN capture.

Version 1.2.291

Released 2026-04-16

Highlights

• J1939 live dashboard with decoded ECU fields and sparkline history.
• Multi-protocol transport reassembly across ISO-TP, ISO-TP CEA, SAE TP2.0, K-Line TP, J1939, CCP, and XCP.
• UDS, OBD-II, KWP2000, and J1939 protocol hints with expandable field details.
• Frame sending tools for single frames, repeated frames, ID sweeps, and custom sequences.
• Quality Test panel for packet loss, duplicate, reordering, latency, and jitter checks.
• JSON plugin system for vendor-specific diagnostic protocols.

Hardware And Platform Support

• macOS USB support for PEAK PCAN-USB FD / PCAN-USB Pro FD, Tactrix OpenPort 2.0, Rusoku TouCAN, and gs_usb-compatible adapters.
• Windows J2534 PassThru support with a bundled bridge for both 32-bit and 64-bit adapter DLLs.
• K-Line capture through J2534 adapters that support ISO 9141 / ISO 14230.
• SocketCAN support on Linux, with Linux packages available on request for the initial release.

Import, Export, And Licensing

• Import support for CL1000, candump, ECUconnect, and PCAPNG logs.
• CL1000 export and TransferData binary extraction.
• Offline 10-day trial and Ed25519 license validation.
• Built-in update checks using the public CANcorder download manifest.

Fixes And Reliability

• Fixed a Windows startup crash caused by restoring window geometry before WebView2 finished initialization.
• Improved extended CAN ID handling for J2534 adapters whose drivers omit the expected extended-frame status flag.
• Improved OpenPort packet resynchronization when USB frame alignment is lost.
• Improved PCAN-USB FD command framing for reliable firmware communication.

Public release history starts with the 1.2.x customer release line. Earlier builds were private development and test builds.
