# Cortex API 2.17.1

**April 11, 2022**

## New Features

### Mongoose Update

The Mongoose library is updated from version 4 to version 5 to address a number of MongoDB-related operational issues.

### Updates to mdctl environment import process

The following changes are made to the environment import process:

* Backups and triggers are **false** by default during import.
* Policies are disabled on environment imports and package install.
* You can add memos before, during, and after an import or export.

### Expression operator improvements

We made some improvements to the following operators:

* Added `init` command to `$moment` 
* Enabled `$let` to pass local values to `$dbNext`
* Added a third parameter to `$pathTo` to allow path setting and deep object creation

### Temporary configuration reader

You can read non-Cortex and non-generic-Axon configurations based on the needs of the [Looking Glass](https://confluence.devops.medable.com/x/YPAHAw) web portal.

### Ability to retroute core objects

You now can reroute core system objects. Previously, you could only reroute custom objects.

### Support for serialize and deserialize during HTTP requests

Support is provided to parse, stringify, and output json, ejson, bson, and mjson.
