Improvements

Improved the default sort behavior for aggregations.

The SQL query IS NULL now seeks out empty values as expected.

Fixed a bug with the Fusion SQL service that prevented a collection from sharing a name with an collection alias.

Previously, SQL aggregations were limited to 250 aggregations. Now, the default limit is 5,000 aggregations, and the limit is configureable. To set the limit to 10,000 aggregations, use the following command:
```
curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d '10000' http://localhost:8764/api/apollo/configurations/fusion.sql.bucket_size_limit
```

Improved how multi-word synonyms are handled by query rewriting.

Bug Fixes

Fixed an issue with the XML Transformation index pipeline stage that prevented it from parsing information from an RSS feed.

Fixed a bug that sometimes caused the Token and Phrase Spell Correction Job to fail with an ArrayIndexOutOfBoundsException error.

Fixed a bug that prevented security trimming from working on the Alfescro connector in Fusion 4.2.4.

Fixed a bug that sometimes resulted in documents on CrawlDB being marked as incomplete when crawl operations were started and stopped multiple times.

Performance is improved in aggregation collections.

Fixed a bug that caused Head/Tail Analysis jobs to fail due to a misconfigured collection name.

Known issues

The Couchbase connector does not work with Couchbase versions 5 or later. This will be addressed in Fusion 4.2.6.

The FTP connector sometimes prevents files with non-English filenames from being indexed.
