Wireshark 5.0.0rc1 Released: New Features, Dropped Qt 5, and What's Changed

Wireshark 5.0.0rc1 is the first major version bump for the packet analyzer in years. The release candidate drops Qt 5 support, ends the odd/even numbering scheme, and adds a new theme engine alongside Zstandard-compressed captures and per-packet process attribution. Deep HTTP/3 dissection rounds out the headline features, though some of it has been available since 4.7.2. The team expects a final 5.0.0 date after SharkFest EU (November 2–6), and packagers should note several breaking changes worth tracking.
