Dear all,
It is with great pleasure and excitement that we are starting a Beta Test period for the W3C Markup Validator:
http://validator-test.w3.org/
The W3C Markup Validation Service, also known as "HTML validator", is a popular free service and software providing Web content authors a way to check Web documents.
The previous stable version (v0.7.4) of the validator was released last November, but work on the version 0.8 had been going for a very long time, and is now reaching maturity. With your help, we can fix remaining bugs, find issues with the documentation, and release version 0.8.0 within a few weeks. If you would like to help with this beta test, please see the section "Testing and reporting issues" below.
Changes
The small version bump between 0.7.4 and 0.8.0 can be misleading: this new version is packed with changes. There are a number of cosmetic and UI changes, but the biggest difference is under the hood: the new validator is using a new library as a wrapper around its main parser, resulting in drastic speed improvements, and a lot of interesting new possibilities.
Users of the validator are probably familiar with the note stating "The Validator XML support has some limitations". Be prepared to say good bye to such a familiar sight: while the 0.8.0 validator is still using the same base parser for validation (the excellent and venerable opensp), it now has an XML sidekick making sure XML-ill-formedness won't go unnoticed.
There are many more changes in this version, below is a summarized list of the main ones:
- New architecture, faster and more reliable, scaling better to the
- Improved interface for better usability, accessibility
- New feature: automatic cleanup of markup (with Tidy)
- New Feature: additional XML-WF check, for more reliable validation of XML-based languages
- Back by popular demand: document outline feature
- New feature: checking that the documents are sent with proper Internet Media Type (MIME type)
- New feature: for XML documents, checking that the xmlns is present, and properly set.
- New Feature: grouped messages, an alternate view to the sequential display of errors
- New Feature: Direct Input form can be pre-filled with basic document structure
- Added support for SMIL 2.1, XHTML Basic 1.1
- ... and quite a few bug fixes, too.
