Release Notes

Release v2.7.0

Added support for comparing variable-length (V) and variable-length blocked (VB) binary files through Block Descriptor Word (BDW) and Record Descriptor Word (RDW) handling. Two new properties hasBdw (default: false) and hasRdw (default: false) can be set in the configuration file or directly in the fileformat file. When enabled, the tool reads BDW/RDW values and exposes them through reserved field names (_BDW_, _BLOCK_SIZE_, _RDW_, _RECORD_SIZE_) that can be used in the fileformat file. The RDW reserved names (_RDW_ and _RECORD_SIZE_) can be used in the DependingOn attribute to define variable-length records. When hasBdw is enabled, hasRdw is automatically enabled. See binary file comparison for details.

Fixed an issue where CSV comparisons without business keys incorrectly reported modified lines as separate "only in left" (deleted) and "only in right" (inserted) entries instead of paired modified lines with column-level differences highlighted. Modified lines are now correctly matched positionally and displayed with per-column diff details in the HTML report.

Optimized comparison including large CSV files (5GB+) with business keys, reducing processing time from 15+ hours to 5-15 minutes (100-200x faster).
Fixed browser freeze issue when displaying HTML reports with large Variable Block columns (up to 32,000 occurrences). Implemented lazy loading with expand functionality and added new properties: isVBColumnsToAggregate (default: false) and minVBOccursToAggregate (default: 100) to control VB column aggregation behavior.
