#  HTML5 Boilerplate [http://html5boilerplate.com](http://html5boilerplate.com)

## Changelog:

### v.1.0 : March 21st, 2011

#### Build Script

	
Files linked via @import will be inlined into the files they are imported to using Corey Hart's CSS Compressor.
	
Environments are definable.
	
htaccess Expires headers are upgraded to 1year, as the filenames are revved
	
Massive rewrite so you can define which HTML, CSS, JS files to operate on in your configurable project.properties files. This allows you to let the build script operate on very unique folder architecture, including non-H5BP projects.
	
Added a source directory option in the build config, so your source files can be in a different directory from the final generated files (useful for other CMSes/frameworks like Django). 
		


#### index.html

	
We use a protocol-relative url for the jQuery include, to prevent the mixed content warning.
	
The order of <meta> tags, <title>, and charset has been documented more extensively now. TL;DR: You are safe to use the boilerplate's order of tags.
	
We've shortened up the Google Analytics snippet.
	
Added an ARIA role attribute to div#main. This assumes your main content goes within that container.
	
IE9 doesn't get it's own conditional class! Yay!
		


#### style.css

	
Added .focusable helper class that extends .visuallyhidden to allow the element to be focusable when navigated to via the keyboard.
	
Anchor links are no longer reset. Basically our reset is the effectively merged with Eric Meyer's recent CSS reset update and also the HTML5 Doctor reset.
	
An unordered list within a nav element will no longer have a margin.
	
All helper classes are now after primary styles to ensure correct overrides and not be burdened with resets. 
	
.visuallyhidden is no longer camelCase, as to be consistent with other classname formats.
	
Updated the specificity of .visuallyhidden rule to make sure it overrides all other declarations. 
	
Removed reset on image elements within table cells as they look ugly alongside multiline texts. Browsers default to baseline alignment for images which works better than top alignment.
	
Increased margin-left on ol, to allow for 2-digit list numbers.
	
Added a print reset on IE's proprietary filters.
	
Print styles no longer prints hash links or javascript links.
	
Updated sub/sup css to make them not be impacted by line-height, so now you can do sub/superscripts without worrying.
		


#### Project

	
Added a humans.txt so you can clarify authorship and tools used
	
Removed YUI profiling. You probably weren't using it anyway.
	
Removed QUnit's unit tests. There is no need to ship with them, really.
		


#### Webserver Configs
#### .htaccess

	
.htaccess is far more documented now. Take a read through it!
	
Changed mimetype of .ico files to "image/x-icon".
	
HTML Manifest files now use .appcache extension instead of .manifest, as per http://html5.org/r/5812.
	
Force deflate for accept-encoding headers mangled by turtle tappers, courtesy of Yahoo!'s research
	
We nerfed some of the directives in case you're on server without mod_headers. (Which is totally crazy, man)
	
Block access to .git and .svn folders.
	
Eradicating Chrome's console warning on WOFF font downloads.
	
More optimizations available if you set the .htaccess details up in your httpd.conf
	
.htaccess now caches .htc files
  
	
Moved all server configurations (except apache's .htaccess) over to the new html5-boilerplate-server-configs repo. Head over there if you are not using Apache. 
	
	
Updated .htaccess and mime.types for ogg formats.
	
Fixed regression where EOT fonts had been excluded from DEFLATE compression
	
Apache version independence: Use mod_filter for compression, with fallback to AddOutputFilterByType directive for legacy versions
	
Added plugin/extension mime types for Safari, Chrome, Firefox

#### nginx

	
Cleaned up cache expires directives.
	
Now includes SVG and font formats for gzipping.
	
expires header bug fixed.

#### IIS

	
Added Flash video mime types to IIS server
	
Fixed some mimetype weirdness that was preventing proper caching



	
Also Google App Engine, Lighttpd, and NodeJS configurations were added


Basically a lot of great updates were made for 1.0. Here are all 220 commits since last release.. You may ask though, do I need to upgrade existing sites? Short answer: nah, you're good.

### v.0.9.5 : October 25th, 2010

Major changes:


Removed -webkit-font-smoothing: antialiased; it makes monospace too thin.
IE conditional classes have moved from the <body> tag to the <html> tag ( #44 ).
Dropped text-rendering: optimizeLegibility as it breaks small-caps, looks odd on Linux machines, and goes invisible on WebOS.
 
Added a IE6 call for the minified dd_belatedpng.
Revised viewport declaration to allow user scaling and clear Webkit console errors ( #37 ).
Updated Modernizr to 1.6 
Added web.config file for Microsoft IIS
Beta release of the Build Script (this is HUGE)
New project scaffolding bash script.

* Fixed textarea stylings and form field treatment for validity. Added default background-color.
* New robust clearfix solution without IE 5.5 hack ( #45 #126 ).

* Dropped text-rendering: optimizeLegibility as it breaks small-caps and looks odd on Linux machines. 
* Lists now have a left margin of 1.8em. Default list-style-type for ordered list is decimal.

* Removed "Star Hack" for checkboxes in favor of .ie7 selector.
