* The reporting database architecture modified to reduce CPU utilization & Implemented database rotation. 

It was observed that real time database writing is hitting hard on CPU, So we have modified the writing method to reduce CPU utilization.
Additionally added a switch to disable real time database write on resource constrained environments.

* Enhancement in reporting performance. Two time faster than the previous release.
    The reporting engine has been enhanced with changes in querying mechanism.
    This ensures that the users are served with the reports at least two times faster than the previous releases' reports.

* Improved analysis of drilled reports.
    It was observed that there were few drilled reports that have not been generated successfully.
    Identified the faults and fixed them to ensure all the drilling goes fine.

SafeSquid for Linux SWG safesquid-2016.0914.1836.3-swg-concept released

* Completely restructured database architecture to reduce database size and enhance reporting performance (3 times improvement).
     The database architecture used by SafeSquid was rapidly increasing the size and causing delays in generating the reports once the database size starts increasing (above 20GB - 30GB).
     Major optimizations have been done to reduce the database size as much as possible and to reduce the time taken in generation of reports with improved querying mechanism.
 
* Complete change in the display of reporting dashboard.
     The dashboard displaying reports is completely changed from the previous versions.
     The bars and graphs used to display the reports have been replaced completely with simple tabular display resulting in more visual clarity for the users.
 
* Migration script available for the users who are using the older SafeSquid releases to import old database to the new database.
     A migration script has been made available on downloads.safesquid.net readily for the existing customers to change the database architecture.
     The migration script easily migrates the existing database to the latest architecture and SafeSquid starts writing to the new architecture.
     This has been done to ensure users won't lose any previous reports.
 
* Critical bug fix for crash due to enabling caching section.
     It was observed that SafeSquid was crashing when users enable the caching section, but it was a rare scenario.
     Replicated the scenario, identified the cause and fixed the crash.
 
* Critical bug fix for crash due to enabling forwarding section for usage with an upstream proxy.
     It was reported that SafeSquid was crashing when it was configured to use an upstream proxy using the forwarding section.
     Identified the bug and fixed it.

SafeSquid for Linux SWG safesquid-2016.0824.1234.3-swg-concept released

* Improved performance of reporting engine with larger databases (30GB).
     The way SafeSquid was querying the database for reports generation was causing delay to render the reports page on the browser.
     Improved the querying mechanism resulting in the faster rendering of reports with database sizes up to 30GB.
     Previously the querying was taking around 5 minutes on a 10GB database, now it was optimized up to 10 seconds on a 20GB database.
 
* Real-time reports are now generated 3x faster.
     Now the reports are generated 3 times faster than that was in previous releases. Can expect much user experience enhancements in near future.
 
* Fix for intermittent SSO authentication prompts on the user's browsers.
     It was observed that SSO authentication wasn't running smoothly because of slowness in the clients machines resulting in prompts on browsers.
     Authentication prompt was given to the user on the browser intermittently when surfing was going on.
     Identified the flaw in such scenarios and fixed it.
 
* Critical bug fix for crash due to abuse of database vacuum options.
     SafeSquid was using vacuum algorithm to reduce the memory utilization.
     But it was observed that using vacuum at inappropriate places was causing crashes.
     The vacuum algorithm is optimized now and efficiently used.
 
* Implemented facility to configure the policies when reports pages are rendering.
     Previously user was not provided to click on configure unless the reports were rendered.
     Now user can click on configure and make policies irrespective of the rendering of reports.
 

SafeSquid for Linux SWG safesquid-2016.0803.1027.3-swg-concept released

Implemented facility for real time update of trusted ca and using the corporate CA as SafeSquid CA and SafeSquid Trusted Authority.

* Updates for trusted CA infrastructure.
      Updates trusted CA bundle regularly. SafeSquid uses trusted CA bundle to verify SSL server's identity.
      This ensures defense against security breaches due to stolen or compromised or expired CA usage.
 
* Implemented facility to use corporate CA as SafeSquid CA & SafeSquid Trusted Authority.
      You can upload corporate CA files via SafeSquid WebUI.
      You can setup your websites with self-signed CA and upload self-signed CA to SafeSquid trusted bundle.
      Your clients can access all your SSL websites seamlessly without even deploying self-signed CA to client browsers.
      If you have corporate CA provided by trusted party, you need not to deploy SSL certificates on client browsers.
      You can avoid downloading and importing of SafeSquid CA certificate.
      Browsers default trusted bundles are enough to verify SafeSquid generated & signed certificates using corporate CA.
      Deployment of SafeSquid becomes much easier for following use cases and you can provide seamless experience to users.
      Proxy aware mode usage with SSL Inspection.
      Reverse proxy mode usage for SSL website protection.
      Transparent proxy mode usage with SSL Inspection.
 
* Fixed issue for bypassed websites and upload content types not shown on the reporting.
      It was observed that the upload content types and bypassed websites are not shown on the reporting page. Identified the issue and fixed it.
