Wordfence Security makes security scan script and visitors script executable on install or upgrade now. * Fixed bug that caused disk space scanning to still show an issue found in security scan summary even when user chooses to ignore the security issue. * Made disk space thresholds 1 and 1.5% space remaining because many hosts have very large disks where 1% is gigabytes. * Made wordfence Security database handle cache deal with concurrent connections to different databases. * Improved Wordfence Security database library's error reporting. * Improved performance when Wordfence Security looks up it's own version during security scans and other operations. * Removed three rules in base wordfence Security htaccess that could cause 500 errors on servers that don't allow these options to be overridden.

Connection to our servers is still via SSL to enhance security. * Fixed a few minor issues. Overall you should notice that scans are much faster now. = 1.3.3 - April 23, 2012 = * Made real-time server polling more efficient. * Entering your API key now automatically starts your first scan. Was causing some confusion. = 1.3.2 - April 23, 2012 = * Reduced the number of database connections that Wordfence Security makes to one. * Modified the memory efficient unbuffered queries we use to only use a single DB connection. * Removed status updates during post and comment scans which prevents interference with unbuffered queries and makes the scans even faster. = 1.3.1 - April 23, 2012 = * Fixed a bug where if you have the plugin "secure-wordpress" installed, you can't do a Wordfence Security scan because it says you have the wrong version. This is because secure-wordpress trashes the $wp_version global variable to hide your version rather than using the filters provided by WordPress. So coded a workaround so that your Wordfence Security scans will work with that plugin installed. = 1.3 - April 23, 2012 = * Minor fix to point to the correct binary API URL on the Wordfence Security cloud servers. = 1.2 - April 23, 2012 = * It is now free to get a Wordfence Security API key. * Premium keys include theme and plugin file security verification which consumes resources on the Wordfence Security servers. * Various bugfixes and performance enhancements. = 1.1 - April 21, 2012 = * Initial public release of Wordfence Security Plugin.
