 == `dynamicPlugins.cache.volumeClaimSpec` removed, dynamic plugin storage now ephemeral (RHIDP-5568)
 
 The `dynamicPlugins.cache.volumeClaimSpec` field has been removed from `values.yaml`, making all dynamic plugin storage ephemeral by default. Instead of the Helm chart managing PVC creation, you must now manually configure ephemeral volume claims under `extraVolumes`.
 
-This change also resolves issues with running multi-replica {product-very-short} deployments, as using a Persistent Volume for the Dynamic Plugins cache previously led to potential write conflicts.

+== Deprecation of `podman` and `ImageStreams` approach for Helm chart mirroring
 
-None.
+The previous method using `podman` and `ImageStreams` for Helm chart mirroring has been deprecated. You are now required to transition to `oc-mirror` for Helm chart and related container image mirroring. This change enables support for fully disconnected and partially disconnected environments, ensuring a {company name}-supported airgapping process.

+== Change in sign-in resolver configuration location
+
+Previously, configuring the sign-in resolver to bypass user provisioning in the {product-short} software catalog required setting `dangerouslyAllowSignInWithoutUserInCatalog: true` at the root of the `{my-app-config-file}` file.
+
+In this release, this configuration has been deprecated at the root level and moved to the resolver configuration section. It now applies specifically to that resolver. For more details, see link:{authentication-book-title}[{authentication-book-url}].
