# Box SDK releases change CollaborationItem item types to FileMini, FolderMini and WebLinkMini

Markdown version of <https://harbyn.com/changes/box/2026-10-01-collaborationitem-types-changed-in-sdk-releases>.

Breaking change - Box. medium severity. In effect.

Box Java SDK v10.19.0 and v5.18.0, Windows (.NET) SDK v10.19.0 and v6.19.0, Node SDK v10.17.0 and v4.17.0, Python SDK v10.17.0 and iOS SDK 6.17.0 change CollaborationItem to use FileMini, FolderMini and WebLinkMini (box-openapi#619). Most of these releases mark it as a breaking change; code that relies on the previous item types must be updated when upgrading.
