Today the first beta version of WebIssues 1.0 was released. It supports migrating existing data from version 0.8.5 of the server, and it will be possible to upgrade it to the final version once it's released. So, although it's not yet 100% production quality, you can use it to evaluate the numerous new features, and to get familiar with the Web Client. I'm awaiting your feedback, which is very important in order to produce a high quality stable release. You can download this version from the development section.
The first version of the WebIssues Manual is included in both the client and server packages; you can also get it from the manuals section. It's not yet complete, but it already contains a lot of useful information for administrators and users of the system. Other important features added in this version are: added support for PostgreSQL databases, installation of default issue types, and a completely redesigned mechanism of caching data in the Desktop Client, which now uses a SQLite database.
