# Siren Platform User Guide

### Siren Investigate Changes

Fixed:

• Fixed a bug in relational buttons that would remove parts of the state if a request from the button was null.
• Completely refactored how automatically generated buttons are rendered to handle the number of requests sent on dashboard navigation.
• Fixed 'Hide Borders' function. It now hides the borders….

Changed:

• Now the upgrade command backs up the configuration index by default.
• Removed some redundant advanced settings (for example siren:zoom).
• JDBC datasources have been removed from the management/saved_objects page.

#### Plugins

##### Graph Browser

Improved:

• Optimized edge-count strategy, reducing time spent on expand actions by half, in some cases.
• Rewrote the logic to compute counts for nodes. Big speed up, no more missing relations.
• Now supports nodes with millions of relations.
##### Access Control

• Added admin.ssl.keyPassphrase option to searchguard ssl options.
##### Multichart

Fixed:

• Fixed bug in Next arrow where it would return to the beginning of the list each time.
##### Gremlin Server

Fixed:

• Siren Gremlin Server now checks that an index mapping exists before trying to fetch the mapping. This prevents a non-blocking error report on startup with no index-pattern.
