V3.5 is the last version before upgrading to OpenACS 5.6 with ]po[ 4.0. The ]po[ team commits to maintain this version at least until 2011Q4.
The focus of V3.5 is stability. For this reason, there are only few additional features compared with V3.4.
We have updated a number of SQL statements to make them faster in larger environments.
Also, we have replaced the "Resource Planning" report with a version that scales for hundreds of projects and hundreds of resources.
A considerable number of bugs have been fixed for this release.
In particular, the ]po[ team is now using the Helpdesk Package internally for tracking "Report this Error" reports per ]po[ version. This way, more then 120 bugs have been fixed. We hope this will improve the overall robustness and "stability" of the system. .
