(J)Wt 4.15.0 is here!

The main focus of this release is performance optimization. Several improvements have been made to significantly reduce the impact of resource messages on Wt’s responsiveness, decrease server-client communication (in both size and frequency), and increase the likelihood of the browser sending an unload signal—which triggers session deletion—when a user closes a tab or browser window.

We have also introduced a new widget: WDateTimeEdit. Combining WDateEdit and WTimeEdit, it allows users to specify both date and time within a single component.

Additionally, a new tutorial on integrating external JavaScript libraries into Wt is now available here, alongside a couple of new examples.

This release also includes several other features, bug fixes, and improvements. Check the release notes for more detailed information.

Binary builds for Windows are available on the GitHub releases page.
