The OWASP ModSecurity Core Rule Set team is excited to announce the
CRS release v3.0.0, short CRS3.

Over 4 years in the making, this release represents a huge step forward
in terms of capabilities, usability and protection. Key features

* Over 90% reduction of false alarms in a default install 
  when compared to CRS2
* A user-defined Paranoia Level to enable additional strict checks
* Application-specific exclusions for WordPress Core and Drupal
* Sampling mode: runs the CRS on a user-defined percentage of traffic
* SQLi/XSS parsing using libinjection embedded in ModSecurity

For a complete list of new features and the changes in this release, see 
the new site of the project
or the CHANGES document on github

CRS3 is the best stable release of the OWASP ModSecurity Core Rule Set.
We advise all users and providers of boxed CRS versions to update their
setups. CRS2 will reach its end of life soon.

CRS3 requires an Apache/IIS/Nginx web server with ModSecurity 2.8.0 or

Our GitHub repository is the preferred way to download and update CRS:
$> git clone https://github.com/SpiderLabs/owasp-modsecurity-crs.git

For detailed installation instructions, see the INSTALL document.

The release is accompanied by a series of tutorials that guide you 
through the 
* Setup of ModSecurity
* Inclusion of the CRS
* Handling of false positives

Our desire is to see the Core Rules project as a simple baseline
security feature, effectively fighting OWASP TOP 10 weaknesses with few
side effects. As such we attempted to cut down on false positives as
much as possible in the default install. Of course this must not affect
the detection capabilities of the WAF. We honestly believe that the
default install of CRS3 brings at least the same level of security and
higher paranoia levels let you protect your site even more tightly.

We are very excited about this release. So excited, we want to make it 
into a movie. As a first step, we designed the following poster:
