Innovations and new features 
Manage InSpire Snapshots in the Mindbreeze Management Center
Snapshots allow you to save and reload the current state of your Mindbreeze InSpire appliance. This can be used primarily to migrate your Mindbreeze InSpire appliance to another appliance. Snapshots can be managed in the Mindbreeze Management Center (MMC). However, please note that snapshots are not complete backups and therefore do not replace backups.
Export results: Excel data type support
When exporting search results, the export format "Microsoft Excel" saves the values of metadata as text by default. With the new option "Use Excel Native Data Types" such numbers and dates are saved directly in numeric or date format. Thus, it is not only possible to calculate directly with such values, but Excel also displays the values in the appropriate format depending on the set language and region.
Multiple Client Services in Mindbreeze Management Center
With this release, Mindbreeze Management Center (MMC) supports all configured client services for Insight Apps, including Designer, search results from the selected client service, and also the Search Experience. These are now available for selection in the MMC as a dropdown in the header area. The selection is saved for the session.
Accessibility improvements
Accessibility has been improved in the area of voting and sorting search results.
New and improved Connectors
Yammer Connector (New)
The new Microsoft Yammer Connector allows indexing of groups as well as messages and replies from Microsoft Yammer. The connector supports efficient incremental processing of Yammer chat messages so that the search is always up-to-date.
Sitecore Connector (New)
The Sitecore Connector allows you to index all types of items, pages or articles from Sitecore. You can choose which types of items to index via "Template Names" and additionally filter items based on their Sitecore metadata. Currently, the Sitecore Connector only supports public content.
Web Connector: Support for authentication when JavaScript is active
With the Web Connector, it is now also possible to index rendered HTML on authenticated web pages. This means that it is now also possible to search Single Page Apps (SPAs) that require a login.
Service Now Connector: Performance Optimization in Principal Resolution Service
The new "KB Article Principals Size Optimization" option in the ServiceNow Crawler and Principal Resolution Service significantly reduces the size of the principal cache. On the one hand, this improves performance during cache updates, and on the other hand, it also improves performance during searches.

Salesforce Connector: Improved indexing of knowledge articles
The new version of the Salesforce Connector now extracts content not only from the previous object types "Document" and "ContentDocument", but can now also extract content from any HTML fields. This significantly improves the search of knowledge articles, for example.
Technical extensions
SAML: Support for Shibboleth 4.0 (AES-GCM encryption)
Mindbreeze now supports SAML authentication with AES-GCM as the encryption algorithm for SAML assertions. This means that Shibboleth 4.0 can be used as a SAML IDP for the Mindbreeze Client Service.
Insight app load time optimization
The loading time of the client.js has been significantly reduced. As a result, (embedded) Mindbreeze InSpire Insight apps can now be loaded much faster by the browser.
