This release adds various minor enhancements:

  • There is a new hotkey for adding an Intruder payload position marker. This is not mapped to any keystroke by default, but this can be done at User options / Misc / Hotkeys.
  • There is a new option on startup to disable extensions. This can help resolve situations where a misbehaving extension causes problems during startup.
  • Burp Collaborator server now responds to DNS lookups containing the subdomain "spoofed" with the IP address 127.0.0.1. This is to prevent the Collaborator being wrongly incriminated when a server being scanned is vulnerable to client IP spoofing, as happened here.
  • The option to strip the "Accept-Encoding" header in incoming requests to the Proxy has been modified so that it normalizes the header to a default value rather than stripping it altogether. The previous behavior caused problems with some WAFs configured to drop requests without this header.
  • The default max heap size requested by the platform installer has been reduced from 75% to 50% of total physical memory, in order to prevent OS performance issues on some platforms. This can be modified after installation by editing the vmoptions file in the installation directory.
  • MacOS App Nap has been disabled as this can cause Burp's automated activity (like scanning) to be suspended when the Burp window is in the background.

Additionally, a number of bugs have been fixed:

  • A bug that caused temporary data saved by Burp extensions and the sessions tracer to actually get stored in project files.
  • A bug that caused the Spider not to honor the "Maximum parameterized requests per URL" setting.
  • A bug that caused some lightweight popups to have full window decoration on some Linux desktop managers.
  • A bug that incorrectly handled loading of IP addresses from file into the scope configuration UI.
  • A bug that prevented upstream SNI from working when proxying traffic through Burp from an Android emulator.
  • A bug that caused report generation to fail altogether when it encountered an incomplete issue due to project file corruption.
