With a few exceptions, this is a record of mainly just user-facing changes—that is, either changes to the actual behavior of the checker, or changes to any options/interfaces the checker exposes for developers.

16.1.1

1 January 2016

  • Java8 is now required to run the checker (and to build it).
  • Made the <meta http-equiv=content-security-policy content="..."> element a non-error & added syntax checking of its content attribute and checking of the value of the Content-Security-Policy HTTP header.
  • Made the Content Security Policy nonce attribute a non-error.
  • Aligned on* event-handler-attribute checking with spec.
  • Aligned iframe[sandbox] checking with spec.
  • Made minlength attribute a non-error.
  • Dropped “heading needed” warning for cases where aria-label found.
  • Made unescaped ampersand a non-error in, e.g. href="foo?bar=1&baz=2".
  • Added error for img[alt=""] w/ role != presentation.
  • Made role=switch a non-error.
  • Made role=group for header & footer a non-error.
  • Made role=search for form a non-error.
  • Made the Subresource Integrity integrity attribute a non-error and added syntax checking for it.
  • Refined bad-URL error message to indicate which character is invalid.
  • Refined Web UI "Message Filtering" to show total error/warning counts
  • Refined Web UI to show green if there are 0 errors or warnings to show
  • Fixed "input[type=hidden] label descendants" bug (@takenspc patch)
  • Refined Web UI to remove background colors and increase font size
  • Made a variety of refinements and fixes to ARIA role checking.
  • Made ol>li[role=menuitem] & ol>li[role=tab] non-errors.
  • Added warnings for use of ARIA roles with implicit-semantics elements.
  • Made nesting of time elements a non-error.
  • Made checker ignore input[type=hidden] label descendants in checks.
  • Improved errors for obsolete media types/features.
  • Fixed bug in checking of the content model for the ruby element.

15.6.29

29 June 2015

  • Added error messages for deprecated CSS media types/features.
  • Changed checking of the accept attribute for input[type=file] to allow file extensions in the value (per spec).
  • Added error for documents that have multiple autofocus attributes.
  • Made the <rb> and <rtc> elements non-errors.
  • Made use of data-* attributes for SVG & MathML elements non-errors.
  • Made use of HTML content in the SVG <desc>, <title>, and <metadata> elements a non-error (per spec).
  • Changed error message for the inputmode attribute to a warning.
  • Fixed a bug that caused spurious error to be emitted for ID references in aria-controls and aria-labelledby with trailing whitespace.
  • Fixed a bug that prevented the command-line checker from being able to check URLs when run in a Windows environment. (patch from @mariusj)
  • Added option to disable log4j when using Java API. (patch from @abrin)

15.4.12

12 April 2015

  • Fixed regression that caused spurious errors for input[type=email].
  • Fixed regression in war caused by missing jar needed for gzip handling.

15.3.28

28 March 2015

  • Renamed from “Nu HTML Checker” to “Nu Html Checker”.
  • Improved error messages for input[type] attribute mismatches.
  • Added support for checking object[typemustmatch] per-spec.
  • Added error message for title element that only has whitespace.
  • Dropped all meta[name] checking. Any arbitrary meta[name] value is now accepted unchecked.
  • Made a couple select/option error messages more precise.
  • Added useragent parameter, for allowing you to specify any arbitrary user-agent string for the checker to use when fetching remote documents.
  • Added option to limit maximum number of errors shown. Exposed thru nu.validator.messages.limit Java system prop & --messages-limit option for the build script. Controls limit on maximum number of messages the checker service will report for a single document before stopping with a “Too many messages” fatal error.
  • Make the API/CLI (command-line interface) emit source extracts & “hilite” info. When you set the --format option to json, xml, xhtml, or html (but not gnu or text), the output now includes:
    • an extract from the doc source (extract field in JSON output)
    • which extract part to hilight (JSON hiliteLength & hiliteStart)
    • error range starting line/column (JSON firstColumn & firstLine)
  • Added full support for checking documents at SNI origins.
  • Fixed regression that caused CLI/API to parse .xhtml docs as text/html instead of using the XML parser.
  • Changed backend handling for the case when the “promiscuous-ssl” option is on (that is, when you’re requesting the doc-fetching backend ignore any SSL/TLS cert errors). This should be a transparent change.
  • Now available from (Maven) Central Repository (nu.validator.validator).
  • Made a number of look&feel refinements to the Web frontend.
  • Replaced all Jena IRI code dependencies with dependency on galimatias.
  • Updated doc-fetching backend to Apache HTTP Components HttpClient 4.4.
  • Upgraded to Jetty 9.2.9 & upgraded many other build/run dependencies to latest versions; e.g., log4j 1.2.17, Apache Commons Codec 1.10.
  • Dropped some dependencies that aren’t actually needed.
  • Changed build to cut dependency download size from ~300MB down to ~16MB.
  • Made change to force java to always use Saxon instead of Xalan.
  • Renamed all org.whattf classes to nu.validator.
  • Did large reorganization/consolidation of sources.
  • Added --javaversion option, to generate class files targeted for particular VM versions (compiles for Java6/1.6 by default).

16 February 2015

  • added new "sizes attr required when srcset specifies width" check
  • added --skip-non-html option to CLI; http://goo.gl/sKjRD5 This change alters the default CLI handling of non-HTML files. Before the CLI by default skipped any files without .html, .htm, .xhtml, or .xht extensions; instead now by default all files found are checked, regardless of extension. The --skip-non-html option provides the old default behavior: it make the checker skip any files without .html, .htm, .xhtml, or .xht extensions.
  • added --javaversion option to build script and changed default build behavior to now generate vnu.jar/vnu.war builds that can run in Java6 VMs (as well as in any newer VMs). To generate a vnu.jar/vnu.war build with a newer/different VM target, use, e.g., --javaversion=1.8.
  • added --stacksize option to build script & removed harcoded stack size
  • fixed several bugs in sizes checking
  • fixed position reporting of bad character refs in title & textarea
  • fixed ARIA checking to allow li[role=separator] & time[role=timer]
  • refined content-type check to treat .csl uploads as application/xml
  • refined "unexpected content-type" error msg to include URL of document
  • refined a few things in TestRunner
  • updated Rhino dependency to rhino1_7R5

07 February 2015

  • made SVG <style> not require the type attribute
  • added initial (liberal) support for ARIA in SVG
  • dropped error for X-UA-Compatible: IE=Edge HTTP header. Thx @zcorpan
  • dropped error for meta[http-equiv=X-UA-Compatible][content=IE=Edge]
  • added version info to jar manifest file
  • made nu.validator.client.TestRunner exit non-zero for test failures
  • made build script explicitly request Python2. Thx @kurosawa-takeshi
