In preparation for the upcoming release of IBrowse 2.5, we have updated the documentation with an addendum for some of the bigger new features and changes since IBrowse 2.4 and 2.3. This is likely to continue to be revised with new information as and when necessary. We have also added the documentation from the ib2.html file supplied with IBrowse 2.4, which gives many details of new features present in 2.4, including WACL, which we suspect some of you may have originally missed ;-).
