December 8, 2017 release notes
Improvements
The custom table API has been updated to allow for object links to be created from one custom table record to another custom table record.
Performance has been improved when using CSV import for CSVs with a large number of records.
Fixes
Changes made to custom fields on features were not appropriately reflected in the feature's history.
The warning message presented on an IP-restricted ideas portal inadvertently included styling notes.
An error prevented custom fields at the product level from being imported via CSV.
An alignment issue with the date picker on the starter roadmap prevented some users from adjusting the roadmap timeframe.
