[4.1.0] - 2026-07-07

Section titled “[4.1.0] - 2026-07-07”

✨ Improvements

Section titled “✨ Improvements”
  • Multiple CSV matrix import: several exported matrices can be selected and then merged into a single analysis.
  • Automatic merging of identical flows on import: packet count and byte volume are summed, and the most recent last_seen date is kept.
  • Improved matrix import panel: the selected files are listed before opening and can be cleared before import.
  • New About menu with separate access to the version information and the embedded changelog.
  • Display of the Npcap version used in the version information.

🛠 Fixes

Section titled “🛠 Fixes”
  • Enriched CSV label import errors: line number, full line and total error count, to make file correction easier.
  • Greater tolerance of label import for extra columns and empty trailing columns.

🔧 Maintenance

Section titled “🔧 Maintenance”
  • Added NPCAP_VERSION to the build versions checked by CI.
  • Bumped the SONAR version to 4.1.0.

[4.0.1] - 2026-07-06

Section titled “[4.0.1] - 2026-07-06”

🔧 Maintenance

Section titled “🔧 Maintenance”
  • Updated the embedded Npcap to 1.88 for the Windows bundles and the Windows smoke runtime.
  • Enabled a strict CSP on the webview.
  • Bumped the SONAR version to 4.0.1.

[4.0.0] - 2026-07-05

Section titled “[4.0.0] - 2026-07-05”

💥 Major changes

Section titled “💥 Major changes”
  • Updated packet_parser to 2.0.2: typed packets, PostgreSQL detection by payload heuristic and new application parsers.
  • Capture engine overhaul: new graphBatch and stopped IPC events, new app_dropped field in the stats event.

✨ Improvements

Section titled “✨ Improvements”
  • Lazy-allocation buffer pool (2 KiB standard / jumbo snaplen): capture memory reduced from ~640 MiB preallocated to a few MiB depending on the real load (bench: RSS 464 → 13 MiB, throughput ×2.7).
  • Graph updates coalesced per node/edge and sent in batches, instead of one IPC event per packet.
  • Application-level drops counted (pool exhausted / channel full) and shown in the status bar (⚠️): visibility on capture completeness under heavy load.

🛠 Fixes

Section titled “🛠 Fixes”
  • The bytes of the first packet of each flow were counted once instead of twice in the matrix and the exported CSV.

🔧 Maintenance

Section titled “🔧 Maintenance”
  • Removed the duplicated CLI processing thread: headless mode shares the main pipeline.
  • Bumped the SONAR version to 4.0.0.

Older versions. The full history (3.x, 2.x, 1.x) is available in the French changelog and in the repository’s CHANGELOG.md.
