-## [Unreleased]
+## [1.15.0] - 2026-05-26
+### Added
+* Credential type of ADF objects is now supported for deployment via REST API
 ### Fixed
+* Starting blob event trigger fails with 'Resource cannot be updated during provisioning' - now waits for provisioning to complete before retrying #484, #474, #463
+* Fixed REST API calls failing with 401 Unauthorized due to Az.Accounts 5.x returning SecureString from Get-AzAccessToken
 * Fixed DryRun not loading deployment state from storage for hash comparison #476
 * README.md updated and new Structured Documentation created
