irond 0.2.4

A new version of the irond server is available for download.

The following changes have been made:

  • Adapt the construction of PollResults to what will be expected from the Specification. Most recent metadata comes last in PollResult. This involved quite some changes.

  • Refactoring of the SubscriptionService while changing the ordering of metadata.

  • Updated log4j httpcore libraries.

  • Fixed a bug where the searcher failed if two different links produced the same hashCode().

  • Bugfix: Searcher would not traverse links already traveled, even if the depth was smaller than in the first round. This could occur with circles in the MAP graph.

  • Bugfix: Remove illegal subscription update optimization.
