Known Issues

None at this time.

Compiler warnings about buffer truncation (snprintf) are informational only and do not affect functionality. These warnings are from GCC's static analysis being overly conservative with maximum theoretical path lengths.

Roadmap (Future Versions)

Potential features for consideration:

  • JSON output filtering options
  • Parallel processing for multi-core systems
  • Incremental extraction (skip already-processed conversations)
  • Custom output templates
  • Search/indexing capabilities
