Markup Validator 0.8.4 released

W3COn Thursday 20th November 2008, the W3C Validator Developer Team has made public a new stable release version of their W3C Markup Validation service, also known as "HTML Validator".

Use it online:
… or download it: it is Free and Open Source Software (FOSS):

The new version, 0.8.4 may sound like a very minor step from the version 0.8.3 released in August, but this new release of the W3C Markup Validator brings some very important change: in addition to checking documents against etablished standards such as HTML 4.01 and XHTML 1.0, the validator can now check documents for conformance to HTML5, thanks to the integration with the html5 engine.

HTML5 is still work in progress and support for this next generation of the publishing language of the World Wide Web will remain experimental. The integration of the html5 engine in the validator should provide experimentation grounds for those interested in trying on authoring in this new version of HTML, as well as a feedback channel for the group working on building a stable, open standard.

For more info on the changes, see the 0.8.4 news entry on the Validator's news page or this little writeup on the W3C Q&A weblog.

You can also install and use this Markup Validator offline in a local network. For convenience use, ready-to-use binary packages for several Linux distributions like Fedora/Red Hat Linux, openSUSE Linux and Debian Linux as well as for MacOSX do exist. For details see Source code availability for the W3C Markup Validator.

Concerning the openSUSE Linux distribution, the w3c-markup-validator packages are part of the distribution, published via DVD media or available online. The most recent release packages are public available at the openSUSE software repository or at its FTP mirrors. As usual, they are also public available here at, built on my own home server for testing purposes, before I officially apply them to the openSUSE Build Service.
