Posted 1034 Words

We have 2 big announcements this month - see the Highlights for details!

There is also a New Contributors section in which we list new people who have started to contribute to ZAP in the last month.

A big thank you to our Platinum Sponsor(s):

For details of other ZAP sponsors see the Supporters page.


ZAP 2.13.0 Release Candidate

Yesterday’s weekly release is in fact the 2.13.0 Release Candidate!

Please give it a try and let us know if you have any problems with it.

Authentication Auto-Detection

ZAP can now detect and configure itself to handle authentication for a range of sites - see Authentication Auto-Detection for more details.

We do need your feedback in order to make this support better.

Other Significant Changes

Unsupportive 3rd Party Services

We have changed the 3rd Party Services page to split out “unsupportive” services which use ZAP but do not contribute back. If you use ZAP via these companies please get in touch with them and ask them how they plan to start supporting ZAP. 😁

Form Handler RegEx Support

You can now match parameters names in HTTP requests using regular expressions using the Form Handler add-on.

Automation Framework Job Times

The Automation Framework has been changed to show how long each job takes to run in both the desktop GUI and in the text results output.

New Contributors

A very warm welcome to the people who started to contribute to ZAP this month!

As this is a new section here are the new contributors for March as well 😁

If we missed anyone then please get in touch ASAP and we will correct that oversight!

GitHub Pulse

Excluding merges, 6 authors have pushed 15 commits to main and 15 commits to all branches. On main, 41 files have changed and there have been 860 additions and 111 deletions.

Excluding merges, 13 authors have pushed 55 commits to main and 55 commits to all branches. On main, 1,141 files have changed and there have been 20,591 additions and 7,570 deletions.

Ongoing Work

We are actively working on improving the authentication experience in ZAP. As mentioned above Authentication Auto-Detection has been released and should make it much easier to authenticate to a range of sites. However many more changes are planned - stay tuned for more details.

Selenium 4
Selenium v4 has been out for a while and we are actively working on updating ZAP to use it. There is a chance that this update could break existing scripts - more details when we have them.

The GraphQL add-on is being updated to include GraphiQL. The GraphQL IDE will be exposed via the ZAP API and all requests made using the IDE will be proxied through ZAP.

NodeJS API Client
The ZAP API NodeJS client and tooling around it were updated in March. The client is pending a release.
