If you installed the .deb package, you can update with:
sudo apt-get update
sudo apt-get upgrade

Source building instructions are available at:
 http://code.google.com/p/modpagespeed/wiki/HowToBuild (the latest-beta branch)

This release has the following new low risk filters that we invite you to enable on your site:

• Flatten CSS @imports (flatten_css_imports)
• Insert Google Analytics (insert_ga)
• Convert Larger JPEGs to Progressive (convert_jpeg_to_progressive)
• Convert GIFs and PNGs to JPEG (convert_png_to_jpeg)
• Resize Mobile Images (resize_mobile_images)

This release has the following new experimental filters; they could be high impact but you should manually verify the results:

• Lazily Load Images (lazyload_images)
• Defer JavaScript (defer_js)
• Inline Preview Images (inline_preview_images)

This releases fixes the following issues:

48 - Support for CSS @import

108 - Parse CSS3 and common proprietary syntaxes

186 - Wysiwyg 2.2 and CKEditor 3.5 on Drupal + mod_pagespeed breaks

196 - InlineCss not parsing @import "url" statements

214 - insert_image_dimensions can break an image's aspect ratio

332 - LoadFromFile should convert %20 to space in URLs

338 - combine_css needs to strip BOM markers before combining

340 - terminate called after throwing an instance of 'std::length_error'

352 - Lightbox2 + mod_pagespeed not working

354 - CSS filter ignores external CSS links with rel='Stylesheet' instead of rel='stylesheet'

355 - DoS under Debian/apache2-mpm-itk

356 - Sites with HTTPS users and no HTTPS mod_pagespeed configuration get log spew

367 - mod_pagespeed strips custom HTML headers

368 - Relative URL not handled properly in inlined css

372 - meta refresh tags within NOSCRIPT tags get converted to HTTP headers even when javascript is enabled

This release adds some new pagespeed.conf options:

• ModPagespeedFetchWithGzip: Request http content from origin servers using gzip.
• ModPagespeedModifyCachingHeaders: Controls whether cache control headers are rewritten.
• ModPagespeedImageLimitOptimizedPercent: Controls whether smaller images are used.
• ModPagespeedImageLimitResizeAreaPercent: Controls whether resized images are used.
• ModPagespeedJpegRecompressionQuality: Controls JPEG compression quality.
• ModPagespeedCssImageInlineMaxBytes: Controls which CSS images are inlined.

This release splits the Cache Extend filter (extend_cache) into three separate filters:

• Cache Extend CSS (extend_cache_css)
• Cache Extend Images (extend_cache_images)
• Cache Extend Scripts (extend_cache_scripts)

The extend_cache filter is now an alias for the combination of all three of these so it behaves the same as before.


This release includes the following miscellanea:

• The handling of missing close tags has been changed to be more in line with the W3C specification (for example, at http://www.w3.org/TR/html5/syntax.html#optional-tags).
• Fixed bug with combine_css breaking when any of the combined files contained a BOM.
• Fixed bug with handling of CSS with data URLs in @imports that caused rewriting to fail.
• Blacklisted more resources that rely on their URL not being changed on them.
• Many and varied small bug fixes and improvements.
