Release History

Fiddler Everywhere v5.4.0

January 24, 2024

Version 5.4.0

NEW

• Add SocketIO decoding for WebSocket sessions
• Add session breakpoints that pause the execution of any session before the request or response is sent and allow for making changes to the raw headers and body data manually
• Update application font and icons for better readability on displays that use scaling
• Remove most of the automatic coloring in the sessions grid and move the coloring logic to rules match conditions. A ruleset that mimics the previous session colors behavior is available on request

 

FIXED

• Network capturing sometimes does not show local IPv6 connections on macOS
• Multiple cookie headers in Composer requests not handled correctly when updating their cookie values
• Adding form data body content in Composer requests sometimes generates wrong request "Content-Type" header
• Session filters might not work correctly if there are custom columns for both request and response headers using the same header name
• Copy as cURL context menu action in sessions grid does not work on some POST requests with form data
• Application crash in specific cases when the user's subscription is updated
• Apply security fixes for third-party dependencies
