Removals
The Disk Usage Metrics log has been removed.

For sites that had large numbers of these items, the size calculation could lead to intermittent performance issues.

AN-149140 - High
For security reasons, the Query Database Smart Service has been updated. Customers cannot run the LOAD DATA LOCAL INFILE command against a MySQL database by default from a Query Database Node in the Process Model. To provide higher security, for Appian Cloud customers, this command was already disabled at the database level for the Appian Cloud database and at the JDBC level for configured MySQL databases. There is no impact or action for Cloud customers. On-premise customers who wish to use this command must set the conf.data.mysql.loaddata.enabled property to "true" and conf.data.load.infile.path property as a comma-separated list of paths to whitelisted directories that contain the files to be loaded. If the required properties are not set, any Process Model using this command will pause by exception at runtime. This command is generally used to periodically load data from files into the database, and so we expect that most customers will not have to take the required action.
AN-149305 - High
JDBC connector configuration property "autoDeserialize" has been set to false for all MySQL database connections, in order to improve security.
AN-151549 - High
Adds additional protection against interfaces with large context memory sizes.

For security reasons, the Query DB Node smart service has been updated. Customers running the LOAD DATA INFILE command against a MySQL instance (only applicable to Configured Data Sources; not applicable to the Appian Cloud database) from a Query DB Node in a Process Model must set the conf.data.load.infile.paths custom property as a comma-separated list of file paths to whitelist the required directories. If the property is not set, any Process Model using this command will pause by exception at runtime. This command is generally used to periodically load data from files into the database, and so we expect that most customers will not have to take the required action described here.

The queryFilter function with an 'in' filter that has many values now performs as expected again. In fact, it is over an order of magnitude faster than it was before this issue was introduced! All query filters have improved noticeably in performance, but none nearly as much as an 'in' filter with many values. This applies equally to uses of queryFilter in the queryentity, queryrecord, and queryProcessAnalytics functions.
