Release Notes 4.3 (February 2026)

Aqua AI Agent Improvements

Aqua now supports a broad set of tools and UI enhancements to streamline everyday workflows.

Create Capsules and Code, Manage Environments, and More

Access to new tools allows Aqua to create Capsules, duplicate Capsules/Pipelines, manage environments and resources, edit metadata and files, suggest packages, perform git operations, create and modify App Panels, and more.

Session Management

Aqua now preserves chat history with a sidebar to view, search, create, rename, and delete chats, with autogenerated chat names.

Additional Aqua UI Improvements

• Flexible layout controls including expand/minimize and dock left/right views.

• Voice input support via a new microphone button.

• Richer content rendering with clickable internal links and full previews for image URLs.

• Auto-refresh support for attach/detach actions, run status updates, and metadata changes—keeping your UI in sync with Aqua's latest work.

No-Code Apps - Shareable Link to Launch CW App

We’ve added a “Copy Run Link” button (with tooltip) to the Share window of release Cloud Workstation No-Code Apps, allowing users to share and launch apps directly without needing to navigate the full Capsule IDE.

Filter Improvements

We’ve made several enhancements to filtering and asset visibility to improve discovery and administration:

• New “Admin View” access filter for admins, providing a single view to browse and search all assets across dashboards and side panels.

• Filters and metadata filters added to all Archive dashboards, making it easier to review archived assets and in an effort to support automated archive and deletion policies.

Public API - User details Added to Responses

We’ve added owner and owner_email fields to the Capsule, Computation, and Data Asset objects, enabling more complete and automated tracking of ownership metadata via the Code Ocean API.

Infrastructure Updates

VPC Flow Logs

A new CloudFormation parameter was added to enable VPC Flow Logs, providing network traffic visibility. Logs are stored in the codeocean-accesslogs S3 bucket.

This parameter is disabled by default, as it generates a significant volume of log files.

Customers who choose to enable it are responsible for monitoring and tracking associated costs.

Access Logs S3 Lifecycle Update

The lifecycle configuration of the codeocean-accesslogs S3 bucket has been updated. The bucket contains load balancer access logs, deployment bucket access logs, and VPC flow logs. Given their rare access, objects will transition to the Infrequent Access tier after 30 days, move to Deep Archive after one year, and be deleted after seven years.

Stack Tags Propagation

Stack tags that are manually set during deployment updates are now propagated to all EC2 instances launched by Code Ocean. Previously, Batch instances and dedicated machines were excluded.

Elasticache Upgrade

Valkey was upgraded from version 8.0 to 8.2. This change may slightly increase the duration of deployment updates.
