# Version 1.51

Version 1.51 includes many improvements and fixes to enhance your in-app experience including detecting when calendars are configure to automatically accept meeting invitations, and a new and improved Integrations experience!

## 🥳 New

### Calendar Auto-Detect

A new detection enabled by default now detects when a Google account is configured to automatically accept meeting invitations — a known social engineering and BEC tactic where attackers send invitations with malicious content, knowing they'll be accepted without review.

This is implemented in the detection: `Google account automatically adds calendar invitations from everyone` .

## ✨ Enhancements

### Redesigned Integrations UI

The [Integrations](/integrations/integration-fundamentals.md) page now puts what you are integrating with front and center.

Native integrations contain recommended default events so you can connect, manage, and troubleshoot your third-party integrations more smoothly.

Don't see your tool on the list? No problem — use a custom integration.

Learn about all the Integration updates in our new [Integration guides](/integrations/integration-fundamentals.md). We'll continue to add native integration documentation.
{% endhint %}

### File searches and detections

Material has long supported detecting files shared with disposable email addresses (e.g., Temp-Mail or 10 Minute Mail). This release introduces a new search filter for this use case: `shared.with_disposable_email`.

The previous filter, `shared.with_freemail`, is still supported but is now deprecated. See the Deprecations section below for more details.

### Disconnected domain notifications

In the unlikely event that an admin in one of your Google or Microsoft tenants accidentally revokes the basic access Material needs to function, we’ll let you know both in the Material UI with a more prominent notice and an automated Slack message. Opportunities to enable additional functionality by granting Material additional scopes will continue to surface in the Material UI.

### API Tokens and Events Documentation Moved

API tokens and events documentation used to be under the API icon in the top toolbar. It's now located on the Integrations page (the puzzle icon):

## :city\_sunset: Deprecations

### Case Events

Beginning with version 1.51, we're retiring some legacy events:

* Existing subscriptions using the `case` events **still work and you can still edit them**
* `case` events can't be use for **new** subscriptions

{% hint style="success" %}
Review the [Case Event Migration Guide here](https://docs.material.security/reference/case-event-migration-version-1.51) for more details.
{% endhint %}

### File Search Syntax

`shared.with_freemail` is deprecated and shouldn't be used for new detections or searches. Use `shared.with_disposable_email` or `shared.with_personal_email`, depending on your context.

***

## 🐛 Fixes

* **Detection status toggle now persists reliably**. Toggling a detection's enabled/disabled state was not always saving to the backend despite appearing to change in the UI. Configuration changes now take effect immediately.
* **Custom branding setting hidden on shared instances.** The **Custom Branding for Outlook Add-ins** setting was incorrectly visible on multi-tenant instances where it doesn't apply. Administrators on shared instances will no longer see it.
* **Cleared issues no longer appear on the phishing simulation page**. Issues linked to cleared issues were showing up on the simulations review page. The page now only surfaces active, relevant issues.
* **Trusted entity recommendations are now domain-scoped**. Recommendations were surfacing across all domains in a multi-domain org rather than being scoped to where the entity was observed. This reduces false positives and prevents inappropriate cross-domain trust relationships.
* **Issue creation date is now accurate**. Newly created issues could display an incorrect creation date. Timestamps now accurately reflect when the case was created.
* **Google Drive analysis reliability improved**. In certain scenarios, Drive file analysis could stall before completing. Analysis now completes reliably, restoring proper DLP and detection coverage for Drive content.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.material.security/whats-new/previous-releases/version-1.51.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
