cWB public releases
===================

cWB-6.4.1 - 2021-12-23
--------------------------------

   - **Highlights**
      This new release ( cWB-6.4.1 ) is a major upgrade of cWB: 
      it fixes minor problems with the previous version and 
      it introduces some new functionalities in the cwb_gwosc command. 
      It is fully compatible (i.e. in terms of results) with the version used for the 
      latest analyses/results on the LIGO-Virgo data collected during the Third Observing run O3.

   - **Release Notes**

      - Added functionality: GWTC 3 events summary
      - cwb_gwosc command extended to include the latest released events from O3b
      - Minor improvements and fixes
      - Besides the old installation system, based on ad-hoc tailored Makefiles, we are currently testing a cmake installation, which will hopefully make it easier to install cWB. Though, this new feature is already functional, 
      we are still not recommending it as the default installation method.
