v1.0.3 released

A lot of minor usability and accessibility fixes (both in administrative interface and application core logic) is this release. More info:

• Added option 'Safe JS combine'. It guarantees that in case of broken JavaScript it will be loaded separately and won't harm other scripts. Here is used try-catch envelope (which reduces a bit performance, so it can be disabled).
• Added Basic configuration set. Basic configuration includes all first-priority performance actions, and it is a bit better than Safe one. But it can fail on a few environments.
• Added welcome screen after installation. Major UI improvement - now there is welcome screen with quick actions and new features right after WEBO Site SpeedUp installation.
• Added Error screen on failed automatic installation. With welcome screen also added Error screen to help understand what is worng (very rarely) with WEBO Site SpeedUp installation (and which actions can be applied).
• Other UI fixes and improvements.
• CSS Sprites logic improvements.
• Improved server environment detection.

WEBO Site SpeedUp v1.0.1

We didn't stop with product improvements, and after major 1.0 release continued to make it better. So here is a scheduled 1.0.1 update.

• Greatly improved CSS Sprites. There were added a few complicated cases to CSS Sprites logic, fixes memory consumption (approximately by 20-50%). Also improved CSS properties in case of complicated selectors restoration.
• Added automated request for 7-day trial key. Now you can test Premium Edition for 7 days (for 1 website) after installation, no performance or feature limits.
• Fixed endless redirects on 404 errors. In some cases side caching with wo.static.php lead to recursive redirects. Such situations were fixed.
• Added 'Share results on Twitter' buttons. Now you can post your optimization results directly to Twitter.
• Minor UI fixes.
• Improved static resources caching in case of symlinks usage.
• Improved external resources fetching (i.e. in case of dynamic background images).

WEBO Site SpeedUp v0.9.7

We are moving to completely stable and featured v1.0 and here is one more update on this way. In the version 0.9.7:

• Improved UI. All icons were recreated and combined to a few of CSS Sprites (via Auto Sprites tool). Now the whole interface loads faster and there are less files in package (update is going also faster).
• Added option to exclude WEBO Site SpeedUp logic. You can define in System Status -> Settings a number of parts of URL to exclude from processing - and they won't be accelerated with WEBO Site SpeedUp. This field has the same syntax as for Server Side Cache exclude option.
• Improved smush.it callbacks. Reviwed some more issues with bunch image optimization of a huge amounts of data. Callbacks from smush.it tuned a bit.
• Improved static gzip tool. Now it can use gzip console tool if it's allowed to be executed from PHP.
• Improved CSS Sprites logic. Fixed a minor issue with ancesting seletroes lookup and improved CSS Tidy merging qualities.
• Improved gzip on CGI enviroments for CSS/JavaScript files.
• Fixed minor compatibility issues.

Version 0.6.4 released

Before 'major' 0.6.5 we improved Web Optimizer a bit with the following things.

• Added cache re-generation instead of cache clean up. Now all files are in cache cleaned up, then Web Optimizer tries to re-generate them. While cache files are being generated website doesn't use Web Optimizer - to prevent CPU overload with clean cache. Only after we have all files ready to be served, we can completely activate Web Optimizer
• Added 5 cache file sets generation on options' save. The approach described above can be used when options are saved.
• Added option to force deflate over gzip for IE6/7. It seems IE6/7 plays with deflate page encoding a bit better than with gzip. So you can now force Web Optimizer to use this encoding for these browsers.
• Added options for better placement of Web Optimizer stamp and link. There was a complete post about Web Optimizer stamp placement.
• Added IfModule for all .htaccess rules. Since there were a few complaints about broken websites after .htaccess usage it's completely safer to add IfModule for all sections. This will block normal behavior of Web Optimizer in case of incorrect server side functionality detection. But won't break the whole website.
• Improved static assets proxy for images. Added graceful degradation to redirect to the resource and fixed a few issues.
• Improved mhtml behavior for Vista. Just disabled with a new set of cache files.
• Improved CSS Sprites behavior for IE6. Added BackgroundImageCache directive for this browser to prevent CSS Sprites blinking.
• Improved Apache modules detection on CGI environments.
• Improved Joomla! plugin / mambot behavior on a few environments.
• Improved dynamic styles' loading on DOMready event.
• Fixed issues with performance / gzip / footer options incompatibility.
