Release Notes

This article outlines the latest updates and enhancements introduced in Curator releases from version 3.6.8 onward, grouped by release version.

For any questions or assistance, please contact IPV Support.

Curator 4.0.1

Compulsory upgrade step: converting asset copies to references

As of Curator version 3.7, assets added to collections are now converted to references instead of full copies, making it easier to manage and maintain them.

When upgrading, you must complete all of the steps included in this guide to ensure all of your assets are successfully converted to references.

NOTE: In systems that have already been upgraded to version 3.7 or newer, where there is no certainty the step was completed previously, this step should still be performed. Repeating the step will cause no harm.

Process Engine (3.2.1.94) and Workflows

Introduction of process pools

Process pools allow you to set a cap on the number of processes of a specific workflow that can run simultaneously. This prevents Process Engine from being overloaded with instances of a popular workflow. Process pools also allow their capacity to be shared fairly between users based on priority rules.

For more information on configuring process pools, please refer to this article.

By default, a Curator Connect Default process pool will be preconfigured on installing/upgrading to the latest version of Process Engine for the management of Curator Connect workflows. This process pool has a cap of 20 processes running simultaneously and allows users a shared limit of 4 processes within the pool, set by default with the following settings:

  • Max Processes = 20
  • User Share Limit = 4

NOTE:
During an upgrade, the latest version of the core workflows zip file (available in the 4.0.1 install package) must be manually installed within Process Engine in order to obtain the latest workflows used by Curator Connect which run within this pool.

Workflow bug fixes

The following bugs have now been fixed, allowing workflows to run more smoothly:

  • Asset deletion now completes even where there were database-stored blobs. The Spawn – Delete Asset V2 (v2.6.3) workflow will now complete successfully even where blobs are stored in the database, removing assets and their files including those stored as blobs.
  • File transfers will no longer fail when using non-URL outputs. The Spawn – Xfer TransferV5 workflow (v1.10.5) now works correctly with non-standard transfer (i.e., not Xfer) devices.

Curator Clip Link (4.0.1.246)

Bug fixes

A number of bugs have been fixed to make things work more smoothly:

  • Subtitles will now display more reliably when playing videos.
  • Using non-Latin1 characters in folder names will no longer affect the display of thumbnails and search results.
  • When a sub-option for a button is selected, the button will continue to be highlighted to show a selection has been made.
  • The Trash folder is now searchable again.

Curator Gateway (1.11.1.187)

Google Analytics patch

  • Unnecessary Google Analytics checks that could cause errors or delays on air-gapped systems have been removed as of this version.

Curator for Adobe (4.0.1.70 (Win) / 4.0.44 (Mac))

Bug fixes

A number of bugs have been fixed to make things work more smoothly:

  • (MacOS-only) arrow key issue has been resolved. Previously, using the left/right arrow keys in input fields (like the search bar) had no effect. The cursor will now move as expected when editing text.
  • When exporting, the sequence selected in the bin will now be automatically chosen in the export dropdown when only one sequence is selected, instead of defaulting to the first in the list.
  • Using non-Latin1 characters in folder names will no longer affect the display of thumbnails and search results.
