- Assay QC States - Configure and use custom states for quality control workflows in assays. Available in both LabKey Server and Biologics. (admin docs) and (LabKey Server user docs)
Biologics
- Expanded Characters in Sequences. DNA/RNA sequences can use expanded characters beyond A, C, G, T, and U. (docs)

LabKey SQL
- SQL Aggregate Functions - LabKey SQL now supports additional aggregating functions such as median, standard deviation, and variance. When executing against a PostgreSQL database, queries can also make use of PostgreSQL-specific aggregate functions, including: correlation coefficient, population covariance, and many others. (docs | docs)
Performance Improvements
- Performance improvements by caching virtual schema metadata - Database schema metadata has always been cached, but beginning with release 19.2.x, table and column metadata for user schemas (i.e., virtual schemas) is also cached per request. This improves performance when processing complex queries.
Sample Sets

- Unique Value Counters in Name Expressions - Generate a sequential ID based on values in other columns in a sample set, such as a series per lot. (docs)
Targeted Mass Spectrometry (Panorama)
- Zip files during upload - .raw and .d directories containing raw data files from Agilent, Waters, and Bruker mass spectrometers are automatically zipped before upload to a Panorama files repository. (docs)
- Premium Features for Panorama Partners - New features available exclusively to members of the Panorama Partners Program:
- Panorama Premium: Outlier Notifications - Panorama Partners Program members can subscribe to email notifications for new QC folder data imports, or only when the number of outliers in a series of imports is over a threshold. (docs)
- Panorama Premium: Configure QC Metrics - Panorama Partners Program members can configure which QC metrics are used for analysis. (docs)

These are the releases that LabKey tests. Older point releases have serious security vulnerabilities, reliability issues, and known incompatibilities with LabKey. For details, see Supported Technologies.
