Wt & JWt 3.2.2, RC1

The layout managers in Wt have been to many users a frustrating feature: while they clearly are very useful and an added value with few alternatives available (unless you restrict yourself to what CSS provides for layout), they were tedious to use and sensitive to strange parameters with overloaded meanings (the dreaded AlignLeft | AlignTop will ring a bell!).

For this release we took on redesigning and reimplementing layout management to get rid of its nuisances and to fix a number of bugs as well. The new implementation is no longer on tables (except in plain HTML), but instead uses absolutely positioned widgets whose position and size is managed using JavaScript.

Still, we kept most of the good things about Wt’s layout managers (in particular their ability to work without the need to fix the size of widgets, as most other solutions require), and we tried to keep the backwards compatibility as good as possible.

See the release notes on details on what might go wrong when upgrading to 3.2.2, and how to solve this.

We know support client-side certificates for SSL connections, which can be used for a two-way authentication of client and server. A small feature example even shows how to extend Wt::Auth to take advantage of this authentication information.
