+## [0.3.4] - 2026-07-06
+
+### Added
+
+- **OAuth / external identity providers** (extracted from FiPlan.Anywhere):
+  - `@maks-it.com/webui-contracts`: `LoginProviderExternal`, `EmailProtocol`, `ServerAuthenticationMethod`, `MsalViewModel`, `IdpRedeemLoginResponse`, `MailboxOAuthPending`, and mailbox OAuth session/query constants.
+  - `@maks-it.com/webui-core`: `startIdpRedirect`, `shouldSkipIdpLoginCallback`, `useIdpLoginCallback`, mailbox OAuth redirect helpers (`collectMailboxOAuthProtocols`, `startMailboxOAuthRedirect`, `useMailboxOAuthReturn`), and `removeParamFromUrl` / `removeParamsFromUrl`.
+  - `@maks-it.com/webui-components`: `ExternalLoginButtons`, `IdpLoginCallbackHandler`, `MailboxOAuthReturnHandler`.
+- `@maks-it.com/webui-core`: `HOSTNAMES_ARRAY_POLICY` for Certs UI account hostname PATCH collections (`identityKey` / `idFieldKey`: `hostname`).
+- `deepDelta` regression tests for Certs/Vault consumer forms — `HOSTNAMES_ARRAY_POLICY`, `ENTITY_SCOPES_ARRAY_POLICY`, `VERSIONS_ARRAY_POLICY`, advanced `ArrayPolicy` options (`rootKey`, `childArrayKeys`, `deleteItemWhenRoleRemoved`).
+
+### Changed
+
+- All `@maks-it.com/webui-*` packages versioned at **0.3.4** with aligned workspace dependency ranges.
+- RepoUtils entry points and docs: `utils/src/` → `utils/` (`Invoke-TestEngine.bat`, `Invoke-ReleasePackage-Single.bat`, `Update-RepoUtils.bat`; README and `assets/docs/NPM_PUBLISH.md` updated).
+- Release secret env vars documented as logical names **`Npm`** and **`GitHub`** (see `utils/engines/release/scriptSettings.json`).
+- Package READMEs document OAuth exports and PATCH collection policies.
+
+### Fixed
+
+- `deepDelta` identifiable-array diff: role-null removals emit the correct identity field (`id` vs `_deltaId`); item deltas are omitted when only `operations` changed (no spurious id-only placeholders).
+

 .SYNOPSIS
    Plugin-driven release engine entry script.
+
+.PARAMETER DryRun
+    When set, plugins that declare mutatesRemote in Get-PluginMetadata validate only (no registry push, GitHub release, or cluster deploy).
+
+.PARAMETER Mode
+    Optional override for HelmSelfDeploy values resolution (single or ha).
+    When omitted, HelmSelfDeploy.deployMode from scriptSettings.json is used (CI/CD default).
+    Manual installs: Invoke-ReleasePackage-Single.bat / Invoke-ReleasePackage-HA.bat.

 .SYNOPSIS
-    .NET Docker publish plugin — build and push container images for .NET apps.
-
-.DESCRIPTION
-    Logs in with credentials from a Base64-encoded username:password environment variable,
-    builds each configured image once, then tags and pushes: bare semver from DotNetReleaseVersion
-    (e.g. 3.3.4), v-prefixed alias (v3.3.4) when different, optional exact shared.tag if it differs,
-    and optional latest.
-
-    Release image tags align with shared.version (same bare semver as Helm chart/OCI when used together); not from Chart.yaml.
+    Shared container image build/push logic for DockerImagePush and PodmanImagePush.

 .DESCRIPTION
    The chart in the repo should keep placeholder version and appVersion (e.g. 0.0.0); this plugin
-    overwrites them with the bare semver from shared context (DotNetReleaseVersion / shared.version,
-    e.g. 3.3.4 — no leading v), falling back to stripping v/V from shared.tag if version is missing,
-    then runs helm package and helm push, then restores Chart.yaml.

+    plugin, e.g. DotNetReleaseVersion or NpmReleaseVersion — no leading v), falling back to stripping
+    v/V from shared.tag if version is missing, then runs helm package and helm push, then restores Chart.yaml.

    Optional pushLatest (default false when omitted): when true, after the versioned push, copies the chart
    to a :latest tag in the same OCI repository using the oras CLI (https://oras.land). Requires oras on PATH.

    Publishes npm workspace packages to the npm registry.

-    Publishes packages in configured order using an API key from an environment

-    workspace root for auth and supports --skip-duplicate semantics via npm.
+    Publishes packages in configured order using npmSecret (logical secret name).
+    Pass the token via an environment variable named like the configured npm secret (e.g. Npm).
+    Uses a temporary .npmrc in the workspace root.

+.SYNOPSIS
+    Podman image publish plugin — build and push images via podman (local podman CLI).
+
+.DESCRIPTION
+    Requires ContainerEngineProbe first. Skips safely when activeContainerEngine is docker.
+    In CI, runs inside the spawned podman builder container (local nested podman, not CONTAINER_HOST).
+    Builds any Dockerfile listed in images[]; not limited to .NET projects.
