Silva 1.6 Final Released

Publication date: 27.March.2007, 17:01

27 march 2007 – Infrae has released version 1.6 of the Silva content management system. This release brings a range of improvements and several key new features, such as automatic PDF and Word file fulltext indexing, Atom/RSS feeds from containers, ‘classic’ list-based menu rendering, and additions to the documentation. Performance has been significantly improved by changing how containers are published and optimizing calls to the metadata service.

Silva Find

The Silva Find extension has been renovated to take advantage of the PDF and Word file fulltext cataloging. It now supports search by all metadata fields, including those in your custom sets. The search and result views can be extensively customized. Silva Find is included in the silva-extra tarball.

Major changes in Silva 1.6

The published state of containers is now determined by the state of the index document, as opposed to nested content, resulting in a significant performance gain.

Index items are now distinguished from simple anchors, and the Indexer content type has been improved. Old index items will be gracefully upgraded.

The page language can now be based on the metadata setting. This also opens up many possibilities for multi-language sites.

Silva now uses ZCML for registration of Silva extensions and the content types they define. See doc/developer_changes.txt. Developers should read doc/extension.txt.

Many i18n changes:

  • New languages
  • i18n fixes

Lots of bugfixes and subtle improvements.

This is one of the best tested final releases in Silva’s history.

Many thanks to all who contributed. See HISTORY.txt in the Silva core package for more information about changes in Silva 1.6. For developer-level changes, see doc/developer_changes. Also see the changes in components such as Silva Metadata, External Sources, etc.
