+## v1.29.0
+---
+
+### Egress Allowlist
+- **Organisation egress allowlist**: Org admins can manage a list of trusted domains via the new `/v2/egress-allowlist` API. Integration `custom_host` values matching an allowlisted domain pass private-network validation. Cloud metadata endpoints are always blocked
+  - [Documentation](/product/ai-gateway/custom-hosts#trusted-custom-hosts-allowlist)
+
+### Logs & Analytics
+- **Cost unit**: Log detail, log list, log export, and analytics responses now include `cost_unit: "cents"` alongside `cost`
+- **Token breakdown**: The generation log API returns a per-request token breakdown, with display names available from a new token breakdown schema endpoint
+  - [Documentation](/product/observability/logs)
+
+### Log Exports
+- **Pagination and search**: The list exports API supports `current_page`, `page_size` (max 100), and `search`, which matches on the export description
+  - [Documentation](/product/observability/logs-export)
+
+### SCIM
+- **Groups on `/Users`**: SCIM `/Users` endpoints can return and manage `groups` when the org enables the `user_groups_enabled` SCIM setting (off by default). `excludedAttributes=groups` is honored, and group replacement on user `PATCH` is supported
+  - [Documentation](/product/enterprise-offering/org-management/scim/scim)
+
+### Agent Gateway
+- **Configurable base URL**: Dashboard examples use `agent_gateway_base_url` from org settings, falling back to `gateway_base_url` and then the default, so hybrid deployments no longer show `agents.portkey.ai`
+- **Agent integration skill**: Fixed an internal server error when saving agent integration skills
+  - [Documentation](/product/agent-gateway)
+
+### JWT & Authentication
+- **Org guardrails**: Fix Organisation Guardrail issue with JWT auth.
+
+### Organisations
+- **Multiple organisations on air-gapped deployments**: Set `ALLOW_MULTI_ORG_CREATION=ON` on the backend to create additional Org.
+  - [Documentation](/product/enterprise-offering/org-management/organizations)
