#Release v0.7.2 * Updated to be compatible with most recent rstan (version 2.19.2). * Added id_plot_cov function for marginal effects plotting of covariates. * Added id_plot_irf for calculating impulse-response functions for AR(1) models covariates.

#Release v0.7.1 * Fixed bug where time series vignette did not show on CRAN screen

#Release v0.7.0 * Implement a Gaussian process prior for ideal points to permit semi-parametric inference * Update id_plot_legis_dyn to allow for overlay plots comparing different time series models * Strength over-time model identification using variational inference fits

#Release v0.6.0 * Set a stricter threshold for vb to 1e-04 to promote more robust variational inference

#Release v0.5.1 * Fixed bugs in plotting functions related to plotting two groups. * Fixed bug in AR(1) model with restricted time variance. * Updated dependencies to rstan 2.18.2. * Added error-catching in covariate creation.

#Release v0.5.0 * New models for Poisson, ordinal-graded response, Normal and Log-normal outcomes. * Time-varying ideal point processes: random-walks and auto-regressive priors. * Time-varying plot functions for ideal points. * Hierarchical covariates for ideal points and item/bill discrimination. * Switched from matrix data input to long data frames.

#Release v0.2.9.1 * Fixed bugs in id_extract and id_make functions.

#Release v0.2.9 * Fixed a bug in the ideal point plot function, and also in the auto_id option in id_estimate.
