Lake2026-05-20FeatureKnown Issues, Cribl Search Release Notes

The following draft provides early access to release notes for the upcoming Cribl Suite product release. Features or functionality described are not considered binding commitments and are subject to change at the discretion of Cribl at any time for any reason without notice. This information should not be relied upon in making purchasing decisions.

Summary
​

Cribl Lake 4.18.0 release extends bring-your-own storage with Azure Blob backing for Lake Datasets, adds S3 storage class selection for AWS Storage Locations, and enables Federated Search v2 Dataset support for faster queries and clearer datatype mapping with Search federated engines.

Important Changes
​

Breaking Changes to Sensitive Information in API Responses
​

API responses for the following endpoints no longer include sensitive information in plaintext:

  • /system/settings
  • /system/settings/auth
  • /lib/database-connections

This affects passwords and password-equivalent attributes such as bindCredentials and client_secret. The values for these attributes are omitted or masked in responses.

What you need to do: Update any automation or scripts that depend on reading these plaintext values from the API responses for these endpoints.

New Features
​

Azure BYOS Storage Locations
​

Cribl Lake now supports Azure Storage Locations, enabling you to use Azure Blob Storage as the backing store for your Lake Datasets instead of internal Lake storage. This provides data residency and cost control benefits of your own Azure environment while still enabling Cribl Lake to manage retention and power fast search and replay across that data.

Select an S3 Storage Class in AWS Storage Locations
​

You can select an AWS S3 storage class for your BYOS AWS Storage Locations, giving you cost control at write time and supporting cost and performance tuning.

Search v2 Dataset Support
​

You can now leverage Federated Search v2 Dataset capabilities with your Lake Datasets. This provides you with faster queries and clearer datatype mapping with Search federated engines.

App Platform (Preview)
​

Use the new App Platform (Preview) to build and run custom apps in Cribl. Apps are packaged UI experiences that call Cribl and third-party APIs, letting you create tailored workflows and front-end experiences that go beyond the built-in product surfaces.

Cribl AI and Copilot
​

Custom AI Provider Enhancements
​

We’ve streamlined AI provider setup with a new 3-step wizard, added support for LiteLLM and OpenAI-compatible endpoints, and introduced Model Tier assignments (Small, Frontier, Reasoning). You can now test model connections before saving and manage providers directly from the AI Settings dashboard.

MCP Integrations for Cribl AI
​

Cribl AI now supports external Model Context Protocol (MCP) servers, enabling AI agents to access third-party tools during conversations. You can connect external servers via endpoint URLs, with full support for authentication headers and external providers using API keys. For maximum security, all credentials are encrypted at rest.

Cribl Copilot Chatbot Toggle
​

Admins can now enable or disable the Cribl Copilot chatbot widget independently of other Cribl AI features. This allows you to hide the chat interface without impacting broader AI functionality. The toggle is enabled by default for consented deployments, preserving existing behavior upon upgrade.

Cribl Copilot Chat: Environment-Aware Operational Queries
​

Cribl Copilot Chat now supports environment-aware queries, allowing Cribl.Cloud users to ask natural language questions about their live deployment configuration. By combining documentation with real time operational data, Copilot can list configured Routes and Pipelines and provide surface system-level warnings and errors directly in the chat. To ensure security, this feature uses read only tools that automatically redact sensitive information and provides answers tailored to your specific Stream, Edge, Search, or Lake environment.

SDK Changelogs
​

The Cribl SDKs help you integrate with Cribl and reduce the need for repetitive tasks. We maintain changelogs for each version of the Cribl SDKs in their GitHub repositories:
