What’s in Passbolt 5.5.0 & 5.5.1?
Zero-knowledge mode for encrypted metadata (all editions)
For teams that prioritize privacy over server-side audit trails, zero-knowledge mode ensures the server never has access to resource metadata. Admins explicitly share the metadata key once a new user completes activation. Until then, actions requiring the shared metadata key (e.g., sharing a resource, moving private items to shared folders) are blocked.

SCIM (beta) on Passbolt Pro
Automate user lifecycle from your IdP. Create, update, and deactivate users without touching the Passbolt UI. The first iteration targets Microsoft Entra ID (Azure AD). Group provisioning will follow once invited-user onboarding edge cases are resolved. Okta is expected to work in most scenarios, but deactivation flows may still need refinement.
