What's new (v4.20)

Dear Users,​
The software has been updated. We have fixed issues, optimized user experience, and added new features. Here’s a plain-language breakdown:​
I. Issue Fixes​
a. Fixed VCI connection failure: The strict restrictions on Mode 81 in the original CAN branch of the protocol stack caused incorrect command sending to the lower-level device; this has now been resolved.​
b. Fixed data stream issues: Resolved crashes of the data stream executor, failure to recognize random sequence numbers, and protocol stack errors when receiving large data.​
c. Fixed text display: Multi-line input is automatically converted to single-line display to avoid confusion.​
d. Fixed system jump/CDB recognition: Eliminated the "parent system undefined" prompt during system jumps and resolved unknown errors when recognizing CDB files without menus.​
e. Fixed update and download issues: Successful updates of lower-level device firmware/config tables and successful downloads of Chinese-version CDB packages are now ensured.​
II. User Experience Optimization​
a. Optimized metric-imperial unit conversion: Removed redundant rules for faster and more accurate conversion.​
b. Updated startup interface: Now cleaner and more intuitive.​
c. Overseas version optimization: Added "Condition Mode" – automatic metric-imperial conversion is performed before numerical comparison.​
III. New Features Added​
a. New data stream functions: Added display of maximum/minimum values; a "function not supported" prompt is shown when the number of data stream entries is empty.​
b. New capabilities: Added the CDBD5XX algorithm; added "Condition Mode" to the overseas version.​
We recommend updating to the latest version as soon as possible. For any issues, please contact [Customer Service].
