Subject: [Laura-announce] New version (v3r6) of Laura++ package released
Message-ID: <67176fdf.n3WVj1a7sq4ndEq0%laura@projects.hepforge.org>


Dear Laura++ users,

We are very pleased to announce the release of v3r6 of the Laura++ package.

The main changes in this release are:

* Change of build system to CMake
  - New instructions for building can be found in the README

* Extension of the K-matrix implementation to allow:
  - Floating of K-matrix parameters
  - Non-zero spins

* Automatic determination of maximum ASq for signal DP model

* Added functionality for N-dimensional Gaussian constraints on fit parameters

* Improved handling of Gaussian constraints when fitting toy samples

* Added functions to fit models that return signal DP amplitudes or
  signal/background DP likelihoods for given DP coordinates

This version also contains the following changes:

* Added examples for generating events uniformly in phasespace or in the
  square Dalitz plot, or according to old version of EvtGen FLATSQDALITZ model

* Added new example using MIPW

* Improved handling of clone parameters in simultaneous fits

* Change to weightEvents routines to store separately the model weight and the
  square-DP Jacobian instead of just storing their product as the weight
  - Added info messages giving instructions on how to use them depending on how
    the input sample was generated

* Updates to documentation, few small bug fixes

* Standardisation of code formatting

Please see the doc/ReleaseNotes.md file for a full record of the changes.
