Wireshark has released version 5.0.0rc2, marking the second release candidate before its first major update in years, which introduces a new theme system, per-packet process tracking, Zstandard compression for capture files, a built-in Lua debugger, and a complete HTTP/3 dissector. This experimental build drops Qt 5 support, removes several legacy features, and requires updated versions of Windows, Npcap, and Qt. The new theme system simplifies color preferences, while process tracking enhances the ability to identify which applications are sending or receiving packets. Wireshark encourages testers to use this release candidate for bug hunting, with the final version expected to launch soon

Wireshark 5.0.0rc2 Released: New Theme System, HTTP 3, and Process Tracking

Wireshark has shipped 5.0.0rc2, the second release candidate ahead of version 5.0, its first major version bump in years. The experimental build introduces a unified theme system to replace decades of individual color preferences, along with per-packet process tracking, Zstandard compression for capture files, a built-in Lua debugger, and a completed HTTP/3 dissector. It also drops Qt 5 support, removes several legacy features, and bumps Windows, Npcap, and Qt requirements. As a release candidate, it's intended for testers to hunt bugs rather than for production use, with the final 5.0 release still to come.
