#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
