R Integration
- Integrate with RStudio Pro - Use RStudio Pro to view, edit, and export LabKey Server data. (docs)

Administration
- Antivirus Scanning - Automatically scan uploaded files for viruses using ClamAV. (docs)

Reporting and Visualization
- Scatter and Line Plot Enhancements - Specify multiple Y axes. Show all data on a single plot or display separate plots per measure. (docs | docs)
- Time Chart Enhancements - Hide the trend line or the data points on a time chart. (docs)

Electronic Data Capture (Survey)
- Date & Time Question Type - An additional question type combining a date picker and time selector has been added. (docs)
Document Abstraction and Annotation
- Document Abstraction: Multiple Result Set Review - Reviewers can now simultaneously see all abstracted results for a given document and select among differing value assignments. (docs)
- Transfer Results between Servers - Batches of abstraction/annotation results can be encrypted and transferred between servers. (docs)
Adjudication
- Adjudication Improvements - Compare determinations regarding HIV-1 and HIV-2 infection separately and raise alerts to infection monitors when there is consensus about a positive diagnosis for any strain. (docs)
Panorama
- Panorama: Normalized Y-axes in QC Plots - Support for normalizing Levey-Jennings and Moving Range plots using percent of mean or standard deviation as the zero point on the Y-axis. (docs)
- Improved Figures of Merit performance - Rendering performance for the Figures of Merit report has been improved. (docs)
- Read Chromatograms Directly from SKYD files - An experimental feature allows you to read chromatograms directly from SKYD files instead of storing them in the database. (docs)
Development and APIs
- Improvements to Experiment.saveBatch - The Experiment.saveBatch action has been modified to support non-assay backed runs. This allows developers to import assay data not associated with a particular assay design. In earlier versions of the API, identifying a specific assay design was required. This change has been incorporated into both the JavaScript API and the R package Rlabkey. (JS docs | R docs)
- Modal Dialogs in JS API - A new JavaScript function in the LabKey.Utils API displays modal dialogs on the page that can have dynamic content. (docs)
- Display PNG Images in Grids - Use a displayColumnFactory to override the display properties of a column to display images and thumbnails. (docs)
- NaN and Infinity Values - LabKey SQL supports constants NaN, INF, and -INF. (docs)
- Domain APIs - The Python and R APIs have been updated to allow for the inference, creation, and update of dataset and list schemas. Also available in 18.2. (Python docs | R docs)
Potential Backwards Compatibility Issues
- Transition to Jackson Serialization - XStream serialization of pipeline jobs has been replaced with Jackson serialization. Modules that currently depend on XStream should transition to Jackson. XStream serialization has also been removed from the API. While it is always recommended to let running pipeline jobs complete prior to upgrading the server, this is especially true for the 18.3 upgrade as any jobs in progress cannot be restarted automatically. (docs)
- Redshift Driver Upgrade - If you are using Redshift with LabKey, download the latest JDBC 4.2 driver and replace the existing driver in your Tomcat lib directory. (docs)
- Changes to CSRF Setting - At 18.3 upgrade time, the CSRF checking setting on all servers will be set to "All POST requests". Site administrators will have the ability to revert back to "Admin requests" for deployments that still need to make their external modules or custom pages compatible with this setting. For release 19.1, we plan to remove the setting entirely and check CSRF tokens on every POST (except for specially annotated actions). (docs)
- ETL Functionality Shipping with Premium Editions - The ETL module is no longer be distributed with the Community Edition. This functionality is now included with Premium Editions of LabKey Server. (docs)
- returnURL Handling - By default, servers will reject returnURL values that are not identified as being to the local server, either by being a relative path, or because the hostname matches the server's configured base server URL in Site Settings. Rejected URLs will be logged to labkey.log with the message "Rejected external host redirect" along with URL details. Administrators may enable an experimental feature in the Admin Console to allow these URLs through again. This is a stopgap to allow for backwards compatibility, if required. In the future, we will either remove the experimental feature and always reject external URLs, or allow admins to whitelist the sites that should be allowed.
Operations
- Support for Java 11 - We recommend upgrading your server installation to Java 11. Oracle is expected to end public support for Java 8 in January 2019, and, as a result, LabKey Server will no longer support Java 8 for the 19.1 release. For details see Supported Technologies.
- Support for PostgreSQL 11 - PostgreSQL 11.1 and above is supported (not the initial PostgreSQL 11.0 release). For details, see Supported Technologies.
- Remove support for PostgreSQL 9.3 - PostgreSQL 9.3 reached end-of-life in November 2018. We recommend upgrading your PostgreSQL installation to version 10 or later. For details, see Supported Technologies.
Extract-Transform-Load (ETLs)
- ETL Definition Editor Enhancements - Define a new ETL using an existing one as a template. Autocomplete while entering XML. (docs)
