Summary:depmixS4 - version 1.1-0 on CRAN
Project:depmixS4 - hidden Markov model classes

The main change in this version is that the main loop for computing the forward and backward variables has been moved into C resulting in considerable speed improvements. Depending on model specifics this results in a 2-4 fold speed increase when fitting models.

Another noteworthy change is the addition of several examples such as a Poisson change point model (with artificial data, see ?responses), and an example of a financial time series (logged returns from the S&P 500, thanks to Chen Haibo for providing the example, see ?depmix).
