 Logs view improvements

For this release, the desktop application's Logs view has been improved. It now includes a search bar to filter logs by URL, method, status code, query, or timestamp:

(Issue #1109)

We also added proper code editors for the request and response bodies in the logs view. They will now display the content with proper formatting and syntax highlighting, and show eventual errors for the JSON format. As a side effect, the bodies are now searchable:

(Issues #368 and #137)

Last modification, the "Last log" link displayed under the response body now shows when the request or response JSON was malformed:

 Admin API

Since the introduction of the admin API in the previous release, we added multiple new features:

 New CLI flags and serverless options

We added new flags to the CLI to allow you to:

  • --disable-admin-api to deactivate the admin API. (Issue #1371)
  • --disable-tls to override the TLS settings and disable it when running in your CI server. (Issue #668)
  • --max-transaction-logs to set the number of logs kept in memory for retrieval via the admin API. (Issue #632)

Similar options have been added to the serverless library.

 TLS and environment variables

Templating is now supported in the TLS configuration, allowing you to use environment variables in the certificate paths and password fields.

(Issue #1371)


You can now open multiple environments at once in the desktop application:

open file dialog showing multiple files being selected (Issue #1187)


  • The PATCH method wasn't working in the callbacks. This is now fixed. (Issue #1364)
  • Fixed a bug were the application could reconnect to the sync server with a previous token after switching to a different account. (Issue #1369)


We updated the libraries and applications dependencies to their latest versions to fix some reported vulnerabilities.
