New Features
This release provides the following improvements:
Apps (Preview): Cribl Marketplace
Cribl Marketplace is the in-product catalog of Cribl-supported Apps. Administrators can install Apps from the catalog without importing package files from App builders or GitHub. You can browse each App’s overview, declared permissions, and external API access to see what is available and what an App will use before an administrator installs it.
Terraform Resource and Example for Apps (Preview)
Use the criblio_app resource to install Apps in a repeatable way with Terraform. You can install an App from Git, a file, or a URL or create a minimal App scaffold. The GitHub repository for the Cribl Terraform provider includes an example.
Important Changes
Notice: Cribl as Code TypeScript and Go SDK Discontinuation
Cribl is stopping active development of the Cribl as Code Go and TypeScript SDKs, which were previously in preview. To give existing users a clear path forward, we are moving the SDKs from the criblio GitHub organization to the Cribl Community GitHub organization and open sourcing them as community resources. This allows customers and community members to continue using the SDKs and build on them, while Cribl steps back from active feature development and long-term support.
The SDKs will continue to be available through their new home in the Cribl Community GitHub organization, where users can keep using them, fork them, and extend them based on their own needs. Customers looking to stay on a supported integration should consider migrating to either the Python SDK, Terraform Provider, or direct Cribl API access. Cribl support will be limited to critical issues only, such as security vulnerabilities or P0 blockers, for the defined transition period. On October 1, 2026, the SDK repositories will be archived and marked read-only.
Corrections
| ID | Description |
|---|---|
LAKE-2492 | Fixed an issue where creating a Dataset failed if you selected an AWS S3 storage location, then switched it to Azure Blob before saving. |
| LAKE-2479 | Fixed misleading Confirm Deletion messaging for the Netskope Direct Access Source. The dialog no longer implies you can delete the Source while Datasets are still attached. |
| LAKE-2512 | Fixed an issue where creating a new Azure storage location could fail after you removed a previous Azure storage location. Creation now handles Azure RBAC propagation delay instead of failing validation immediately. |
| LAKE-2630 | Zscaler Direct Access now parses NSS events at ingest. Events land with _time from the event timestamp, promoted top-level fields, empty sentinel values dropped, and sourcetype preserved for search (zscalernss-web, zscalernss-fw, zscalernss-dns, zscalernss-tunnel). Create the Dataset with a sourcetype Lake Partition. See Zscaler Direct Access. |
| AI-4275 | Cribl Copilot no longer crashes when an external MCP server is configured with an invalid URL. The invalid server is skipped gracefully. |
| AI-4669 | Organizations that previously opted out of AI features are now correctly preserved during upgrades. AI settings remain disabled as intended. |
| AI-4693 | Improved upgrade reliability so that AI consent and provider settings are correctly retained when configuration is rehydrated from replica or Git sources. |
Security Fixes
| ID | Description |
|---|---|
AI-4653 | Authentication header values for external MCP server connections are now obscured by default, with a show/hide toggle for when you need to view them. |
