Currently, private endpoints for App Services are only available using Amazon Web Services (AWS).
For more information, see Private Endpoints for App Services.
-
New App Services deployments now deploy Sync Gateway 3.3.0
This minor release includes a few internal scalability, indexing, and security-related optimizations. Upgrading to this version does not require any changes to clients to take advantage of the optimizations, which are available automatically on upgrade.
Starting with Sync Gateway 3.3.0, customers can request Capella support to disable the
GET /{keyspace}/_all_docsoperation on their upgraded clusters. Disabling this feature improves performance and prevents potential misuse of this REST API.For more information about all changes within this maintenance release, see the Sync Gateway 3.3.0 Release Notes.
June 2025
-
New App Services deployments now deploy Sync Gateway 3.2.5
This release includes:
-
Improved attachment handling in replication. It is now correctly verified that
_attachmentsis a top-level property before processing attachments. This prevents errors when documents contain the string_attachmentselsewhere in their content. -
Fixed
MgmtRequestfunction that fetches metadata or settings from Couchbase Server’s REST API panic if the HTTP request fails. -
Updated go-blip to log using the BLIP connection ID instead of the HTTP correlation ID to improve traceability between Sync Gateway changes and BLIP logs.

App Services 3.2.2 or later is now fully compatible with Eventing Services on operational clusters that use Couchbase Server 7.6.5 or later.
The Eventing Service can run one or more Eventing Functions in your cluster to handle data changes according to a real-time Event-Condition-Action model. This update adds the ability to create Eventing Functions that can read and write data from a keyspace (bucket, scope, or collection) that’s linked to an App Services App Endpoint. This expands previous capabilities, which only allowed for read-only bindings.
To create an Eventing Function to use with App Services, you must enable the App Services Compatibility setting.

-
When a bucket linked to an App Endpoint is backed up and then restored.
-
When an App Service is deleted, then recreated and associated with the same cluster.
-
After App Services scaling and upgrade operations.
This enhancement removes the need to update these URLs in your application code or in your firewall configurations.
-
March 2024

User-specified CORS Configuration per App Endpoint in Capella App Services
Cross-Origin Resource Sharing (CORS) is a core web security concept allowing users to specify how resources on App Services should be accessed from a different domain via client-side HTTP requests, such as browser-based or PouchDB applications. Users can now configure CORS in App Services on an App Endpoint basis, providing flexibility in configuring how CORS rules in their applications should interact with App Services.
For more information, see CORS Configuration for App Services
February 2024
-
Support for Multiple OpenID Connect (OIDC) Providers in Capella App Services
Open ID Connect (OIDC) authentications allows users' applications to use Couchbase for data synchronization, delegating the authentication to a third-party server known as the Provider, such as Google+ or PayPal. Users can now configure multiple OIDC Providers in App Services per App Endpoint and use them in their client applications. Specify a Default Provider to simplify client flows, as all client requests are handled by the Default Provider unless explicitly defined otherwise.
For more information, see Set Up an Authentication Provider.
December 2023
-
Hashicorp Terraform Provider 1.0.0 for App Services
Version 1.0.0 of Terraform Provider for Capella is now available.

-
Extended Attributes(XATTRs) for more secure Access Control and Data Validation in Capella App Services
You can now store channels and roles as User Extended Attributes (XATTRs) on Capella App Services. This is a more flexible alternative that uses metadata to store access grants outside of the document content, which can then be used to make access control and document routing decisions.
Go to XATTRs for App Services to start using XATTRS for your apps.
November 2023
-
Real-time Log Streaming now available on Capella App Services
Log Streaming provides real-time streaming of App Services operational logs to third-party observability platforms such as Datadog or SumoLogic or self-hosted HTTP logs collectors. Gain insights into application behavior, enable rapid issue detection and resolution to enhance application reliability, performance, and security.
Available at App Services 3.1.2 or higher for Dev Pro and Enterprise customers. Data transfer costs for Log Streaming are billed at the same rate as all other egress costs from App Services
-
Pre-authorize support to take action on failing App Services
Use Request prompt action for cluster recovery to pre-authorize Capella Support to quickly take remediation actions on clusters or App Services that are in a critical health state. Keep this feature enabled at all times to minimize service disruptions.

-
HIPAA compliance for App Services
HIPAA compliance currently excludes App Services, which will follow-on in a future release.
See the Cloud Trust Center for additional information on the security controls and compliance of the platform.
-
App Services: Persistence of deleted documents & metadata purge interval
App Services deployments will retain deleted documents in the server cluster for a period of 60 days following deletion.
This allows disconnected clients to sync down deleted revisions when they come back online, anytime within the 60 day period.
This only impacts clusters with linked app services deployed after this release.
August 2023
-
On/Off Schedule for App Services
You can now turn off your non-production provisioned clusters when you are not using them, allowing you to save on costs. Turning off your cluster turns off the compute for your cluster but the storage remains — this means that all of your data, schema (buckets, scopes, collections), and indexes remain, as well as your cluster configuration, including users and allow lists. You can turn on and off your cluster on-demand or using a schedule. For example, you can set a schedule for your development cluster to be on from 9 am to 5 pm on week days and off at all other times. Any linked App Service will also be turned off when the linked cluster is turned off.
March 2023
-
App Services Self-Service Maintenance Schedules
Capella now automatically notifies you about upcoming upgrades and maintenance jobs on App Services clusters that you manage. A new self-serve maintenance screen enables you to upgrade your App Service, reschedule upcoming maintenance jobs or set your preferred maintenance times.
