Silva 1.5 released

Publication date: 2.February.2006, 18:33

2 february 2006 – Infrae has just released version 1.5 of the Silva content management system.

Silva 1.5 is the first Silva release that really starts using Zope 3 technology in the core, and is the first step in a longer evolution. It does not have a lot of externally visible feature changes, but focuses on making Silva work with Zope 2.8 and Five 1.2.

Some of the changes:

  • Silva now uses Zope 3 interfaces. SilvaLayout (to be released) does not have to create Zope 3 marker interfaces anymore.
  • Silva now uses the Five/Zope 3 i18n architecture. PlacelessTranslationService is not in use anymore.
  • Use Zope 2.8 style ZODB transactions.
  • Some view code has been converted to be based on Zope 3 views.
  • Some adapters have been converted to be true Zope 3 adapters.

See doc/developer_changes.txt in the Silva core package for more details about these changes. And of course a lot of bugs have been squashed: see HISTORY.txt in the package for complete details.

What is Silva?

Silva is an enterprise-class CMS for managing content for the web, print, and other media. Content is stored in clean and future-proof XML, independent of layout and presentation. Features include a multi-version workflow system, XSLT rendering support, integral WYSIWYG editor (Kupu), content reuse in multiple publications, sophisticated access management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation.
