Fluxzy Desktop v1.25.53

New features

  • Multiple instances are now supported. Opening a capture file launches a dedicated view-only instance, allowing easier side-by-side comparison of sessions. This auxiliary instance cannot perform captures. You can restore the previous behaviour by setting the environment variable FLUXZY_DISABLE_MULTIPLE_INSTANCE=1.
  • Export to .http format is now available. This representation displays flows in an HTTP/1.1-style layout, even when the underlying transport is HTTP/2, making it simpler to share and review capture sessions.
  • Timestamps are now visible in the exchange table. Long intervals are shown in full time format (hh:mm:ss,d), while short intervals appear as millisecond deltas for quicker reading.

Fixes

  • Improvements to general capturing behaviour, addressing several edge cases where a stream could previously be disrupted.

Others

    • Clearer diagnostics when transport errors occur (HTTP 528).
    • Corrections around capture stability and stream handling.
    • Strict SSL validation enforcement when operating in Bouncy Castle mode.
  • Dependency updates.
