Opal 6.2 Released
We are pleased to announce that Opal 6.2 is now available. Opal is OBiBa’s core data management application for biobanks.
This Opal release includes:
- Versions of a view: the history of changes of a view, its entity filter and its derived variables can be browsed, compared and restored. A script can be viewed at any version.
- Tags of a view: a version of a view can be tagged, for instance to mark the one used for a publication. A tag can be downloaded, restored, or used to create a new view.
- Views using a table: the table page lists the views that refer to it, and a table or a view cannot be removed or renamed while a view uses it.
- Permissions: changing how a view computes its values requires access to the values of its sources, and only a system administrator can delete tasks.
- SAS Transport: the deprecated SAS export is replaced by the SAS Transport (XPT) format.
- DataSHIELD R parser: the parser of the DataSHIELD R expressions (DataSHIELD4J 3.0) follows the R operator precedence, accepts ranges, divisions and negative numbers in formulas, and rejects assignments in aggregate calls.
- Performance: the entities of the views are cached on disk and kept across restarts.
See the full release notes for the complete list of changes.
