  - The methodological paper was published as: Heidi Seibold, Torsten
    Hothorn, Achim Zeileis (2019). "Generalised Linear Model Trees with
    Global Additive Effects." Advances in Data Analysis and
    Classification, 13(3), 703-725. doi:10.1007/s11634-018-0342-1

  - An introductory vignette was added showing illustrating the package
    by replicating the empirical analysis from the journal publication.

                 Changes in version 0.9-1 (2020-05-15)                  

  - Bug fix in prediction with new observations.

                 Changes in version 0.9-0 (2018-01-16)                  

  - Initial release of the palmtree package for partially additive
    (generalized) linear model trees. The estimation uses an EM-type
    algorithm similar to glmertree.

  - Details of the algorithm are described in: Heidi Seibold, Torsten
    Hothorn, Achim Zeileis (2016). "Generalised Linear Model Trees with
    Global Additive Effects." arXiv:1612.07498, arXiv.org E-Print
