Genero front end delivery

All the v5.00 front-end clients will support both Genero v4.01 and Genero v5.00. No new v4.01 front-end packages will be released; anyone needing a maintenance release for their v4.01 front-end installations will need to use the v5.00 front-end packages.

GBC & Universal Rendering

Most of the features listed below have been introduced in v4.01 releases of the Genero Browser Client. There have been significant improvements in performance, especially around scrolling tables and the handling of table columns.

In addition, there are additional features that may interest you.
