Opencast 13.10

The tenth maintenance release of Opencast 13.

This release fixes an endless loop occurring on certain search terms in the Admin UI and External API. The loop would fill the Opencast log with ElasticsearchStatusException messages potentially leading to quickly growing log files filling up the server.

Additionally, the following changes are part of this release.

• Test for broken JAR (zip) files (#5157)

See changelog for a comprehensive list of changes.

Opencast 13.9

The ninth maintenance release of Opencast 13.

The release fixes corrupt zip headers in the distributed jar files. This was causing Opencast to fail at startup in combination with a recent OpenJDK security update.

The alternative to updating to this release is to run Java with -Djdk.util.zip.disableZip64ExtraFieldValidation=true. Setting this will disable the new security check.

Additionally, the following changes are part of this release.

• Only show Asset Upload for options of correct type (#5117)
• Index rebuild fixes (#5115)
• Mark tag operation as skipped if nothing happened (#5108)

Opencast 13.0

Features

• New Plugin Management. Some parts of Opencast have become plugins and are now disabled by default but can be easily enabled again by flipping a single configuration option. (#3218) For a list of plugins, take a look at
  • etc/org.opencastproject.plugin.impl.PluginManagerImpl.cfg or the
  • documentation: The Plugin Management Documentation
• Comments in the event index. Adds comment reason, text and resolvedStatus to the events index. This allows for filtering events by certain comments in the Admin UI by using the searchbar. For example, if you are using the notes column in the events table, you could search for all events that have a note that contains "silent". This requires an index rebuild. (#4029)
• Support for f4v file type (#4280)
• Whisper as new Speech-To-Text engine. The new engine comes with additional configuration options and with a config file to choose what model to use and the CLI command. (#4513)
• Specialist worker notes added. Adds the ability to define a list of worker nodes that gets preferred when dispatching compilation jobs (Job Type: org.opencastproject.composer). This could for example be useful in a setup with one or more GPU accelerated nodes. (#3741) This feature is disabled by default and only activated when a list of specialized worker nodes is set. The comma-separated list of worker nodes is defined in the configuration file:
  • etc/org.opencastproject.serviceregistry.impl.ServiceRegistryJpaImpl.cfg To ensure backwards compatibility not defining a list of specialized worker nodes is safe and leaves the behavior of the system unchanged.
• The new assert workflow operation allows asserting that certain expressions are true or false. This replaces the similar failing operation. (#4358)

Improvements

• Much faster fading effect for cuts from the video editor. (#4013)
• Default resolution of live schedule impl changed to standard 16:9 (#4098)
• JobDispatcher extracted from inside the ServiceRegistry into its own class. This makes the JobDispatcher a configurable OSGi service, such that dispatching can be enabled or disabled during runtime. Also changes the default job dispatch behaviour to not dispatch jobs, and alters the node profiles to enable it by default on the expected nodes. This should not change current job dispatcher behaviour, aside from being able to enable or disable job dispatch on the fly. (#3607)
• Multi-tenant clusters can now define a common metadata catalog per tenant. (#4181)
• PostgreSQL is no longer considered experimental and fully supported. (#4359)
• The send-email workflow operation now has the following improvements:
  • Templates can now include values from all extended metadata catalogs. Previously, the flavor of the extended catalog had to start with dublincore/. (#4376)
  • Templates can now include values from organization properties. This can be useful for multi-tenant systems. (#4380)
  • send-email can now send multipart emails using text and HTML. (#4408)
• User details can now be mapped from LDAP attributes. (#4440)

Behavior changes

• Navigation shortcuts to switch tabs in modals for new events and new series in admin-ui. The combinations are: alt + enter for next or - if applicable - the create button, and alt + backspace for the previous button (alt == option on macOS). Note: Shortcuts will not be detected while <input> or <select> elements are focused. In most cases, you will need to press the enter-key first. US translations for the hotkey cheatSheet are included and can be seen by pressing the ? key while the modals are open. (#3998)
• Extended metadata of events and series are put into the Elasticsearch index. This can be used to filter by extended metadata fields via the full text search. The series extended metadata is indexed by the Series Service and the event extended metadata by the Asset Manager. (#3274)
• Theodul Player is disabled by default and will be removed in OC 14 (#4315)
• The LDAP implementation has been simplified, which may require adapting the etc/security/mh_default_org.xml configuration file. (#4383)
• Captions are now published in the default workflows. (#4415)

API changes

• New endpoint to the External API Events endpoints. It allows uploading a track to an event by sending the updated media package to the archive. It also allows removing all other tracks of the specified flavor. It does not start a workflow. (#3670)
• The ingest API now allows setting tags when ingesting attachments or catalogs via URL. (#4156)
• The ingest API now allows downloading from HTTP sources protected by HTTP basic auth. Previously only digest auth was supported. (#4180)
