OCLC has released CONTENTdm version 5.2.
Here's an excerpt from the press release:
With the new release, the CONTENTdm Project Client now supports auto updates, enabling users to get updates as quickly as they are available. It automatically checks for software updates in the background, so work is not interrupted. If updates are available, they are downloaded but not installed until the organization is ready.
To better support text-based collections, PDF print quality can now be specified in the Project Client, enabling users to select a quality level when generating optional print versions of their compound objects. For users with large, full-text collections, several enhancements improve performance and reduce indexing times. Other enhancements include the addition of a new thesaurus, Canadian Subject Headings (CSH), and configuration options to filter hits in Usage Reports.
