Changes from CPAchecker 3.0 to CPAchecker 4.0
---------------------------------------------
* Improved default configuration of CPAchecker.  
  The default configuration of CPAchecker is now more advanced and effective.
  For standard reachability properties it now uses strategy selection on
  program features such as the whether loops exist to choose a particular analysis.
  In most cases, a parallel portfolio of a diverse range of analyses such as
  k-induction, IMC, predicate abstraction, and value analysis is used.
  Parallel portfolios of different analyses are also used for verification of
  memory-safety and termination properties.
* Initial support for handling `atexit`.
* The generated HTML report does no longer contain the witness tab by default.  
  In some cases, it can take a long time to generated.
  Set the option `report.addWitness=true` to re-enable it.
* On 2024-10-18 the CPAchecker repository was migrated from Subversion to git  
  Please see our [post on the migration](https://groups.google.com/g/cpachecker-users/c/1s6YbhvKq6Y/m/ElnLV4CkAAAJ)
