Lightrun Release Notes🔗

Here's where you'll find the latest Lightrun release notes, including the main highlights, enhancements, and fixes made to each version as it is released.

For a monthly, high-level overview of major product updates, see the What's New page — a curated summary of the most significant features released each month.

Lightrun release cadence

Lightrun follows a consistent and predictable release cadence, enabling organizations to choose between early access to new features and more thoroughly tested versions.

The release flow differs based on the deployment type:

  • Cloud-first releases: A new release is deployed to the Lightrun Cloud every two weeks. This environment receives the latest features, enhancements, and bug fixes first.
  • Single-tenant and On-premise releases: These environments receive the same updates one week after the Cloud release, following additional validation and packaging.
  • Quarterly Support Releases (QSRs): Once per quarter, a version is designated as a Quarterly Support Release. These versions are explicitly marked as QSR in the release notes (e.g., Version 1.55 QSR) and are maintained with critical security patches and fixes for high-impact issues until the next QSR becomes available. These version undergo extended backward compatibility testing and are ideal for environments that require longer upgrade cycles.

Backward compatibility

The Lightrun server supports agents and plugins released up to 12 months prior the server release. This only includes agents and plugins with the same major version as the server.

Additional resources

  • Functionality changes and deprecations: A consolidated list of feature changes, parameter changes, and deprecations across releases. Each change is also documented individually in the release notes. Before upgrading to a new version of Lightrun, we recommend reviewing this list of changes as it may include breaking changes that require your attention.

Version 1.76 🔗

Release date: 13 January, 2026 (SaaS, Single-Tenant, and On-Premises to follow next week)

Feature Enhancements🔗

All plugins: Plugin upgrade without server (On-Premises only)

Starting with version 1.76, admins can respond immediately to IDE changes, allowing developers to continue working with minimal disruption. Previously, the Lightrun server had to be updated by an admin for developers to get an updated plugin. Because server upgrades often occur infrequently, this resulted in delays, operational friction, and unnecessary downtime. As an admin, you upload an IDE plugin version through the Lightrun Management Portal. The uploaded file replaces the existing latest plugin file can be download from the Getting Started > **Install the plugin in your IDE* page, or obtained by contacting Lightrun Support. For more information, see Upload and distribute a Lightrun plugin independent of the server version.

Node.js Agent: Deploy Lightrun on Google Cloud Functions

Lightrun now supports deployment on Google Cloud Functions (Gen2) for Node.js, enabling real-time debugging and observability in serverless environments running on Cloud. This release includes a step-by-step deployment flow using the Lightrun Node.js agent, with support for deployment via the gcloud CLI or Cloud Build. For more information, see Deploy Lightrun on Node.js Google Cloud Functions.

Lightrun Management Portal: Find Your Lightrun Admin in Seconds

You can now view your organization’s Lightrun admins directly from the User Management page. View permissions have been extended to allow users to identify admins without requiring admin access.

Version 1.75 🔗

Release date: 4 January, 2026 (SaaS, Single-Tenant, and On-Premises to follow next week)

Highlights🔗

Lightrun MCP: Runtime Context for AI Coding Assistants

Lightrun MCP enables AI coding assistants such as Cursor, Gemini, and Copilot to inspect live application runtimes using Lightrun’s production-safe, on-demand capabilities.

Through the Model Context Protocol (MCP), AI agents can retrieve runtime information as needed—without requiring code changes, rebuilds, or redeployments. This allows AI tools to inspect call stacks, variable values, and execution flow precisely when and where issues occur.

Lightrun MCP operates via a MCP server embedded in the Lightrun server, that securely connects AI tools with running applications over HTTPS. The result is faster root-cause analysis of complex, non-reproducible issues directly within real runtime environments.

To get started, see:

Version 1.74 🔗

Release date: 21 December, 2025 (SaaS, Single-Tenant, and On-Premises to follow next week)

Feature Enhancements🔗

Enhanced Lightrun Tag Management Mechanism

We’ve introduced a new mechanism for deprecating Lightrun tags. Previously, tags created by terminated agents remained indefinitely, causing lists to grow unnecessarily and making it harder to distinguish active tags from inactive ones. Company Admins can now configure a Remove Unused Tag Interval—available in the Service Configuration page of the Lightrun Management Portal—to automatically clean up inactive tags, ensuring a cleaner, more manageable tag list across both the IDE Plugin and Lightrun Management Portal. For more information, see Service Configuration.

Bug Fixes🔗

Fixed security vulnerabilities in the Lightrun server.

Version 1.73 🔗

Release date: 2 December, 2025 (SaaS, Single-Tenant, and On-Premises to follow next week)

Feature Enhancements🔗

Node.js Agent: Improved Node.js agent running on AWS Lambda

Optimized warm-start performance of a Node.js agent running on AWS Lambda. For more information, see Deploy Lightrun on AWS Lambda with Lambda layers.

JetBrains IDE Plugins: Lightrun Plugin Support for JetBrains Version 2025.3

Lightrun is now compatible with JetBrains IDEs version 2025.3, ensuring continued support and seamless debugging experience.

Version 1.73.1🔗

Release date: 9 December, 2025 (SaaS, Single-Tenant, and On-Premise)

Bug Fixes🔗
  • Fixed an internal issue related to the Lightrun server.

Version 1.72 🔗

Release date: 18 November, 2025 (SaaS, Single-Tenant and On-Premise to follow next week)

Feature Enhancements🔗

JetBrains Plugin: Compare Cross-Snapshot Hit Variables

As part of our ongoing initiative to enhance snapshot debugging capabilities, we’ve introduced the compare cross-snapshot hit variables feature.

This enhancement enables developers to directly compare variable values captured across multiple snapshots within JetBrains. By using the Add as a column to the hits table option — accessible via right-click in the Snapshot Hit tab within the Snapshot Console — you can now add a dedicated column displaying variable values side by side.

This streamlined comparison helps you quickly identify when and where application state diverges, leading to faster and more precise root cause analysis during debugging. For more information, see Work with Lightrun Snapshots in the JetBrains IDE.

.NET Agent: Full Support for .NET 10.0

Lightrun now fully supports .NET 10.0, enabling seamless debugging and observability for applications running on the latest .NET version.

Bug Fixes🔗
  • Fixed internal bugs in the Lightrun server.
  • Fixed security vulnerabilities in the Lightrun server.

Version 1.71🔗

Release date: 5 November, 2025 (Single-Tenant and On-Premise to follow next week)

Feature Enhancements🔗

Lightrun Management Portal: Added Scoped API Keys

As an extension of Persona-based roles previously released, Lightrun now supports Scoped API Keys, giving organizations fine-grained control over what each API key can access. Instead of full, unrestricted access, API keys can now be limited to specific scopes — such as Company, Dev, or Security — aligning access with the principle of least privilege.

Previously, all API keys provided unrestricted access to all endpoints, creating potential security, compliance, and operational risks. Scoped API Keys introduce permission boundaries that help enterprises:

  • Reduce security exposure by limiting access to only what’s needed.
  • Simplify compliance with internal and external least-privilege requirements.
  • Improve auditability by enforcing and demonstrating access boundaries.
  • Enhance developer experience with safer automation and integration options.

Scoped API Keys can be configured across the following areas:

  • Company Scope – Manage organization-wide settings: users, groups, identity providers, API keys, integrations, and feature flags.
  • Dev Scope – Manage runtime access, agent pools, actions, temporary access, agents, tags, and debugging runbooks.
  • Security Scope – Access security operations, Runtime Reachability, SBOMs, and package monitoring/enrichment.

For more information, see Lightrun System API Keys.

HEADS UP NOTICE: REVIEW SCIM-MANAGED RBAC GROUPS BEFORE UPGRADING TO UPCOMING ROLE MECHANISM

As part of Lightrun’s powerful new role management mechanism, to be introduced in a future release (starting from version 1.67), we are enhancing how permissions and group structures work together, offering greater flexibility and control over your access model.

If your organization uses RBAC and manages groups via SCIM, take note of the following change: Privileged users (for example, users with the ignore quota permission) who currently belong to standard groups will be moved to a new group that SCIM does not recognize after the upgrade.

This may affect group synchronization and visibility within your identity provider.

Important: Click to review before upgrading

To ensure a smooth upgrade:

  • Review group assignments to determine if any privileged users are assigned to standard groups.
  • If no privileged users are in standard groups, no action is required.

  • If privileged users are present in standard groups, consider the following options:

    1. Temporarily remove elevated permissions (such as ignore quota) from those users, when possible.
    2. Permanently remove elevated permissions from those users and use temporary access.
    3. Remove and create a new group for the privileged users.
    4. Move the users to a dedicated group created specifically for privileged users.

HEADS UP NOTICE FOR SAAS USERS - JAVA AGENT: UPCOMING CHANGE TO SNAPSHOT HIT LIMIT IN JETBRAINS

Starting in version 1.57, the snapshot hit limit will now apply across all agents collectively, rather than per individual agent.

So what’s Changing?

Previously, when setting a Snapshot Max Hit Limit (default: 1), the limit applied per agent. For example, with 100 agents, users expected a total of 100 hits (1 per agent). However, this led to excessive traffic and unexpected behavior.
From version 1.57 onward, the hit limit will apply globally across all agents

Why the Change?

  • Improved Usability: Prevents unexpected additional hits.
  • Better Predictability: Developers can now precisely anticipate snapshot behavior.
  • Enhanced Performance: Reduces unnecessary load, optimizing large-scale environments. This update ensures snapshots function as intended, enhancing efficiency and control

How Does This Affect Me?

  • Automatic Change: This update has been applied at the SaaS server level, meaning it takes effect even if you have not updated your plugin.
  • New Behavior: The max hit limit now represents the total number of snapshots across all agents.

Introducing Lightrun Dynamic Traces for Java in JetBrains IDE

We are excited to introduce Lightrun Dynamic Traces enabling real-time tracing of code execution by capturing Trace Snapshots across requests or transactions. This provides a clear, chronological view of how different parts of the code interact, helping developers debug complex workflows with reduced background noise.

Dynamic Traces provide powerful insights into your application's behavior, helping you efficiently debug and analyze complex processes. Here’s why you should use them:

  • Real-Time Debugging: Capture and analyze code execution as it happens, offering a live view of how your application processes user requests and transactions.
  • Troubleshoot Complex Workflows: Track multi-step, branched flow processes with ease, grouping snapshots in chronological order to clearly understand the sequence of events.
  • Focus on Specific Flows: Pinpoint issues in targeted user requests or transactions, isolating problems across different parts of the code.
  • Seamless Context Tracking: Maintain the state of key variables across snapshots, offering consistent visibility into how data evolves throughout the execution flow. For more information, see Lightrun Dynamic Traces overview.

To learn how to create, run, and analyze a Dynamic Trace, see Work with Lightrun Dynamic Traces for Java in JetBrains.
