Announcing ContraxSuite Version 1.6.0!

The COVID-19 pandemic has affected every aspect of global life. As more and more people work from home, the development and improvement of sophisticated software has become even more integral to revitalizing the economy. Meanwhile, other systemic changes like the LIBOR transition and legislation like the CCPA have changed the legal landscape in more pervasive and permanent ways. Contract analytics tools are becoming table stakes as the world continues to confront the challenges of living and working in 2020.

For all these reasons and more, we are proud to announce the latest version of ContraxSuite Extraction & Analysis. In this release, one of our biggest of the past three years, we have made uploading documents faster and more efficient, expanded user features, and added helpful tooltips. We have also created and developed a new Clause-Level review tool that allows document reviewers to see exactly the clauses that need their attention, without having to scroll through contracts that could be dozens – if not hundreds – of pages long.

Version 1.6.0 is the twenty-eighth open source release, and one of our largest. It became generally available on June 9th, 2020. Read on for a detailed description of the latest updates to ContraxSuite.
