4.5.2.1

• A new format argument has been added to the extractor functions cond_logLik, eff_sample_size, filter_mean, filter_traj, forecast, pred_mean, pred_var, and saved_states. This allows the user to extract the relevant elements in data-frame format if desired.

• pomp no longer depends on the superseded packages reshape2 or plyr.

• pomp has a new dependency on the package dplyr.

• The magrittr pipe %>% is no longer re-exported by pomp: use the native R pipe, |>, instead.

• The package now requires R version 4.1 at least.
