Release notes

(GitHub issue/PR numbers in parentheses)

Fixes

• Images in vignettes should now render properly using png device. Thanks to
  TJ Mahr. (#51)
• xaxis_title(FALSE) and yaxis_title(FALSE) now set axis titles to NULL
  rather than changing theme elements to element_blank(). This makes it easier
  to add axis titles to plots that don’t have them by default. Thanks to Bill
  Harris. (#53)

New Features

• Introduce ppc_error_hist_grouped for plotting predictive errors
  by level of a grouping variable. (#40)
• Introduce mcmc_recover_intervals for comparing MCMC estimates to "true"
  parameter values used to simulate the data. (#56)
• Add argument divergences to mcmc_trace function. For models fit using
  HMC/NUTS this can be used to display divergences as a rug at the bottom of the
  trace plot. (#42)
• Introduce bayesplot_grid function for juxtaposing plots and enforcing shared
  axis limits. (#59)
• The stat argument for all ppc_stat_* functions now accepts a function
  instead of only the name of a function. (#31)
