A detailed technical change log for this update (4.51) is available, and our what’s new page has been updated with a summary of the new features.
Bursting with knowledge
The helpdesk is a hive of knowledge and activity. Your team creates knowledge when interacting with and solving your customer’s issues, and knowledge is captured using Kayako’s easy-to-use self-service tools.
We want to make it easier to release and exploit the full potential of that knowledge helpdesk throughout your organization, which was the driver for the new self-service support added to the Kayako API.

You can now capture new self-service content from other apps and services and share your existing self-service content stored in the helpdesk. Fetch, create, update and manage knowledgebase articles and categories, troubleshooter and helpdesk news postings. Find out more about in the Kayako developer wiki.
Kayako Mobile looking great on the iPhone 5

Kayako Mobile for iOS has been updated to take full advantage of the new, elongated iPhone 5 display.
Now you can see more information, tickets and ticket replies with less scrolling and navigation.
The latest Kayako Mobile for iOS with this update is now available in the App Store.
Custom fields now available in a pocket… near you*
Kayako Mobile for Android and Kayako Mobile for Windows Phone now support custom fields in tickets. You can now access the custom fields of your tickets on the go – ideal for work in the field and getting the full picture on the go.
We will bring custom field support to Kayako Mobile for iOS soon.
(* Ok, that may have sounded better in our heads.)
