We are pleased to announce the immediate availability of MISP v2.4.159.  This releases includes many improvements, bug fixes and improvements concerning performance on large datasets.

# Performance Improvements

- [DB] Add MysqlExtended DboSource to support index query hints.
- [Query] Add new setting to disable taxonomy checks when browsing data.
- We discovered that some MISP users are still using slow file-based session handling in PHP. Now, we added in the diagnostic, if session is file based. We recommend everyone to use the Redis session.
- Many additional speed-up and faster functions in the MISP internals.
- Reduce memory usage when generating all correlations.

# Improvements

- [Feed] Allow option to disable correlations for all events coming from a feed. This can be useful when correlation requires to be disabled for an imported feed.
- [UI] Allow to upload MISP event by pasting data to textarea in addition to the file upload.
- An optional feature `clusters:attachMultipleClusters` is now available to allow the mirroring of attribute clusters to event.
- [auditlog] Support for fetch event changes from specific time.
- [UI] Allow to filter attributes from Related Events box.
- [UI] Allow to filter attributes from warninglist box. 
- [UI] Many UI improvements to make the interface easier to read.
- [UI] Disable correlation checkbox for non correlating types.
- [STIX 2 import] Better Galaxies parsing by looking for the ATT&CK technique id.
- [API] Enable sharing group filter for Event controller not just attribute.

# Fixes

- [STIX] Avoiding non RFC-4122 UUIDs to be imported (and therefore skipped)
- [STIX 1 import] Save process network connections.
- [STIX 1 import] Fixed galaxy tag_names fetching from TTP names.
