v1.5

Released August 6, 2025

New features

Documentation

• The administrator guide is now versioned. View the current administrator guide
• Published 100 GbE performance results for version 1.5. View the benchmarks

Traffic-generation platform

• Added L2 MAC-address configuration to stateless plugins. Generating L2 headers independently also makes MAC moving and ARP Flood scenarios possible
• Added HTML Meta Refresh and HTTP redirects, such as 307 Redirect, for HTTP/1.1 and HTTP/2. Users can also configure the maximum number of redirects, which defaults to 20
• Added support for redirects from HTTP to HTTPS

Improvements

Traffic-generation platform

• Migrated every stateless plugin from raw-socket TCP/IP to direct DPDK interaction, increasing overall performance
• Every stateless plugin can now use either a valid or an invalid L3/L4 checksum
• Aggregate statistics are now more accurate and stable. Metrics are collected at the DPDK ingress and egress instead of when the Peresvet ST TCP/IP stack generates a packet
• Significantly refactored HTTP- and TLS-family plugins to improve stability above 100 Gbit/s

Web interface

• New networks and MAC addresses can now be created directly from a plugin instead of requiring a visit to the Networks and Agents page
• Updated the favicon and browser-tab titles
• Included other small UX and visual improvements

Fixes

Traffic-generation platform

• Corrected HTTP/1.1 and HTTP/2 response processing that could produce invalid statistics and gradually degrade plugin performance
• Fixed a gradual memory leak in ClickHouse Server
• Enforced the configured size limit for packet captures
• Corrected L3/L4 checksums that were always invalid in TCP plugins
• Prevented new HTTP/2 streams from stopping at high test rates above 100 Gbit/s

Web interface

• Prevented the interface from hanging after a forced logout, such as when the same account is used to sign in on another computer
• Prevented a task search for nonexistent data from hanging the interface until the page was reloaded
• Corrected the interface is nil, not string error during authentication-token refresh
