# Release Notes: 2014-06-11

In the wake of our monster updates last week (you can check the release notes [here](/archived-release-notes/2014/2014-06-04-release-notes.md)), our release this week contains a few bug fixes and minor feature additions. Check out the list below and [let us know](mailto:support@thousandeyes.com?subject=Release%20Questions) if you have any questions.

## New BGP alert rule option

When an IP is announced via multiple prefixes, false BGP alerts can be thrown if one of those prefixes is no longer reachable.

Let's use the example **1.2.3.4**, which is announced through these network prefixes:

* **1.0.0.0/8**
* **1.2.0.0/16**
* **1.2.3.0/24**

The only network prefix we're really interested in is the one with the longest prefix (**1.2.3.0/24**). Therefore, we can craft an alert rule that excludes prefixes 1.0.0.0/8 and 1.2.0.0/16 from alerting. To do so, I would create the alert with the following criteria. Note the selection of the second metric and operator.

![](/files/-M5xtX8bOvbPfHlX9qTW)

This will force the alert processor to consider only the /24 prefix desired when determining whether or not to trigger alerts.

Another approach would be to configure the alert to be based on Prefix is in (1.2.3.0/24), however we've gone with the **not in** approach in order to allow this rule to be reused on other tests. Working with an exclusion list rather than an inclusion list allows for greater flexibility.

## Create ICMP network tests via API

A \`protocol\` field can now be specified when creating network tests via the ThousandEyes API. This can be set to ICMP when creating new network tests. Check the [ThousandEyes developer reference](http://developer.thousandeyes.com/#/changesummary) site for more information.

## 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.thousandeyes.com/archived-release-notes/2014/2014-06-11-release-notes.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.
