AI writes code fast, but it can’t know your business rules or security needs. Here is why AI-generated code still needs tests and human review.
GPT-6 Luna is now available for Bugster as both a model hosted by OpenAI and by us. The elmah.io-hosted option is available for Enterprise users. When picking the OpenAI-hosted model, you still need to provide your own API key. You will find the configuration for Bugster on the Organization Settings page.

The elmah.io Deployment Notification and elmah.io Upload Source Map extensions for Azure DevOps now run on Linux and macOS agents as well as Windows. Both tasks are available as version 5.
Until now, both tasks were written for Azure DevOps’ PowerShell handler, which only runs on Windows agents, so a step on an ubuntu-latest agent failed with “The current operating system is not capable of running this task”. Version 5 is rewritten in Node.js, which every agent type can run.
To upgrade, change the task version in your pipeline. Inputs are unchanged:
- task: ElmahIoDeploymentNotification@5
- task: ElmahIoUploadSourceMap@5
In classic release pipelines, select task version 5.*. Version 5 requires agent 3.232.1 or newer, which all Microsoft-hosted agents already run. It also fails the step if elmah.io rejects the request, for example because of an invalid API key, and shows elmah.io’s error message in the step log. Pipelines still on version 4 keep running on Windows agents.
The documentation has been updated for deployments from Pipelines, deployments from Releases, and uploading source maps from Azure DevOps.

The IP addresses used by elmah.io Uptime Monitoring have changed in all regions. If you allow our uptime agents through a firewall or similar by IP address, you will need to update your allowlist. Europe North and Europe West were the most out of date, and some requests were coming from addresses that weren’t on the published list.
You can find the current IP addresses per region in the Allowing elmah.io uptime agents documentation. If you allow requests by User-Agent (elmahio-uptimebot/2.0) instead, nothing needs to change.
Google has deprecated Gemini 3.5 Flash, so we have replaced it with Gemini 3.6 Flash in Bugster. Existing Bugster configurations using the old model have been updated automatically. You will find the model selection on the Organization Settings page.
Cloudflare has been added to the list of sub-processors. We use Cloudflare as a web application firewall and content delivery network in front of our websites. That means Cloudflare processes the IP address and request details of visitors in order to filter malicious traffic and deliver pages.

ASP.NET Core patterns for designing AI-agent-ready APIs: DTOs, idempotency keys, pagination, machine-readable errors, and fine-grained auth.
We’ve added visualizers for a few more values on the Server Variables tab:
Accept-Language shows a flag and the language name next to each entry, like en-US,en;q=0.9.sec-ch-ua and sec-ch-ua-full-version-list show the browser name and version with a browser icon.sec-ch-ua-platform shows an icon for the operating system, like Windows.sec-ch-ua-mobile shows a device icon and whether the value means true or false.
There’s a new page on the documentation site explaining how to Add the elmah.io MCP Server to Antigravity.
We added a sample showing how to log from a Blazor Web App to the Elmah.Io.Blazor.Wasm repository. It combines Elmah.Io.Extensions.Logging (plus Elmah.Io.AspNetCore.ExtensionsLogging) in the Server project with Elmah.Io.Blazor.Wasm in the Client project, covering all four Blazor render modes: Static Server, Interactive Server, Interactive WebAssembly, and Interactive Auto. Blazor Web App is now the first section on the Blazor docs page: https://docs.elmah.io/logging-to-elmah-io-from-blazor/

The MCP server now exposes six new tools for managing log messages: messages_hide, messages_unhide, messages_fix, messages_open, messages_bot, and messages_unbot. These let an AI client hide noisy messages, mark errors as fixed (or reopen them), and flag messages as bot traffic (or undo that), directly from a conversation with Claude, Codex, or another MCP client.
messages_hide, messages_fix, and messages_open accept an optional flag to apply the change to every other message sharing the same grouping hash, while messages_bot and messages_unbot take a list of up to 500 message IDs per call. All six tools only act when a user has explicitly asked for that specific change, never speculatively while an AI is just investigating errors.
The documentation has been updated to include the new tools.

Bugster, the helpful AI agent on elmah.io, just received an improvement that can significantly improve the answers to your questions about your logs: source control access. In the Bugster configuration, you can pick either GitHub or Azure DevOps to allow Bugster to look up source files in your repositories. The connection is configured on the Organization Settings page, while picking a repository is available on the Log Settings page. This allows for configuring the connection once and then picking individual (or the same) code repositories per log.
Check out the updated documentation to learn how to set it up: Give Bugster access to your source code.
