Release 4.2.x

This article describes the changes of the version 4.2.x update.

Note: We have released a 4.2.9 hotfix that solves a performance problem in connection with the schema registry, which led to an extremely long connection process or missing schemas for some users.

Note: 4.2.7 is the first official 4.2. release recommended for all 4.1.x Kadeck Web users. However, some customers might have already received a 4.2.x version from us.

Important upgrade notes (must read)

Kadeck Teams completes the transition from the old Kadeck 3.x to our new platform. In the course of 4.2, more updates are planned that will further improve existing components.

Kadeck Teams 4.2.x sets the stage for a variety of new features to be added in the coming months.

  • Kadeck Teams replaces Kadeck Web. All Kadeck Web users will automatically upgraded to the new Kadeck Teams Enterprise version.
  • The image tag has changed from xeotek/kadeckweb to xeotek/kadeck . Please change your deployments to use the new image tag.
  • The attribute and search filters have been revised. The functions have been extended. Depending on the functionalities used, the filter results can now be different:
    • A "contains" (<>) now also works on whole json objects. This is also true for the negated operator. I.e. it is now possible to determine whether objects within objects contain a certain field. See example [1] below.
    • Strings in attribute filters no longer need to be surrounded by apostrophes.
    • Attribute filters without an attribute will test the whole value or key.
    • Support for tombstones was added: filtering for null now also works on the key and value level.
  • We added anonymous error reports were introduced that help us identify errors. You can turn off the error reports in the settings.

[1] New "Contains" Example:

An attribute filter with contains(<>) = mailbox will return the following record as the address object contains a mailbox field. 

{key:null, value: { "address":{ "zip":12345, "city":"Musterstadt", "mailbox":"M1931"}}
