 Description: Fit Bayesian Dynamic Generalized Additive Models to sets of time series. Users can build dynamic nonlinear State-Space models that can incorporate semiparametric effects in observation and process components, using a wide range of observation families. Estimation is performed using Markov Chain Monte Carlo with Hamiltonian Monte Carlo in the software 'Stan'. References: Clark & Wells (2022) <doi:10.1111/2041-210X.13974>.

 # mvgam 1.1.4 (development version; not yet on CRAN)
 ## New functionalities
 * Added a `stability.mvgam` method to compute stability metrics from models fit with Vector Autoregressive dynamics (#21)
+* Added functionality to estimate hierarchical error correlations when using multivariate latent process models and when the data are nested among levels of a relevant grouping factor (#75); see `?mvgam::AR` for an example
+* Added `ZMVN()` error models for estimating Zero-Mean Multivariate Normal errors; convenient for working with non time-series data where latent residuals are expected to be correlated (such as when fitting Joint Species Distribution Models); see `?mvgam::ZMVN` for examples
+=======
 * Added a `fevd.mvgam` method to compute forecast error variance decompositions from models fit with Vector Autoregressive dynamics
