On 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: http://validator.w3.org/
… or download it: it is Free and Open Source Software (FOSS): http://validator.w3.org/source/

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 Validator.nu 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 sierkbornemann.de, built on my own home server for testing purposes, before I officially apply them to the openSUSE Build Service.

0.8.3 is mostly a maintenance/bug fix version, but it also has a few nice new features, especially for developers.

For more info on the changes, see the 0.8.3 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. Because I am the maintainer of these packages, they are also public available here at sierkbornemann.de, built on my own home server for testing purposes, before reaching the official openSUSE Build Service.

IEBlog tells us with its newest entry from 19th December 2007, that the unbelievable and from many web developers around the world long wished capability of the Internet Explorer on the path to web standards compliance comes true: the forthcoming and heavily in developing state being Internet Explorer 8 will pass the Acid2 test! The IE developer team, working hard on their next version of Internet Explorer, has checked in lots of code into the core rendering engine in the last couple of days, that enables IE 8 to pass the test of the WaSP.

Today sees the 13th release of the W3C Markup Validation service since, well, since the W3C started making formal releases for what was then known as the HTML Validator.

0.8.2 is mostly a maintenance version, with a number of bug fixes, a big performance fix, and a few UI improvements for accessibility and usability. It is now, among other things, easier to:

• revalidate a document, even in the direct input or file upload modes
• use the validator with a screen reader
• validate standalone SVG documents
• validate a specific representation of a content-negotiated resource

These changes and more are listed in the validator's news page.

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 do exist (see Source code availability for the W3C Markup Validator).

Since openSUSE 10.3, the w3c-markup-validator package at version 0.8.1 is included as an official part of the openSUSE 10.3 distribution. As the releases before, the most recent release packages for openSUSE Linux are public available here at sierkbornemann.de, at the official openSUSE software repository or at its mirrors.

Version 0.8.1 of the W3C Markup Validator, a bug fix release in the development of the validator, has been released today by the W3C Quality Assurance Team. It adresses the following issues:

• Bug Fix: changed set up of parser responsible for checking XML well-formedness, which would retrieve schemas for entities each time the validator would run.
• Bug Fix: the validator would incorrectly complain about HTML/XML named entities (such as ©).
• Bug Fix: fixing referer checking when running with Apache and mod_perl2.
• Bug Fix: the validator would crash when called from browsers with rare language preference settings
• ... and small performance and code cleanup fixes

For details of the changes, please read the News for the W3C Markup Validator.

You can also install and use this Markup Validator offline, meaning on a local host or local network. For convenience use, ready-to-use binary packages for several Linux distributions like Fedora/Red Hat Linux, openSUSE Linux and Debian Linux do exist. See Source code availability for the W3C Markup Validator for further information about how to get these packages. Official openSUSE packages of the W3C Markup Validator are public available again here at sierkbornemann.de, at the official openSUSE software repository or at its mirrors. The w3c-markup-validator package is also scheduled to be an official part of the openSUSE 10.3 distribution.
