Bug fixes

• Fixed issue with retrieving draws with models with spaces in their names. (#453)

• Fixed bug with spaces in path to the temporary folder on Windows. (#460)

• Fixed issue with not reporting model executable name clashing with folder name. (#461)

New features

• New function as_cmdstan_fit() that creates CmdStanMCMC/MLE/VB objects
  directly from CmdStan CSV files. (#412)

• read_cmdstan_csv() now also returns chain run times for MCMC sampling CSV
  files. (#414)

• Faster CSV reading for multiple chains. (#419)

• New $profiles() method for fitted model objects accesses profiling
  information from R if profiling used in the Stan program. Support for profiling
  Stan programs requires CmdStan >= 2.26. (#434)

• New vignette on profiling Stan programs. (#435)

• New vignette on running Stan on the GPU with OpenCL. OpenCL device ids can
  now also be specified at runtime. (#439)

• New check for invalid parameter names when supplying init values. (#452, @mike-lawrence)

• Suppressing compilation messages when not in interactive mode. (#462, @wlandau)

• New error_on_NA argument for cmdstan_version() to optionally return NULL
  (instead of erroring) if the CmdStan path is not found (#467, @wlandau).

• Global option cmdstanr_max_rows can be set as an alternative to specifying
  max_rows argument to the $print() method. (#470)

• New output_basename argument for the model fitting methods. Can be used in
  conjunction with output_dir to get completely predictable output CSV file
  paths. (#471)

• New format argument for $draws(), $sampler_diagnostics(),
  read_cmdstan_csv(), and as_cmdstan_fit(). This controls the format of the
  draws returned or stored in the object. Changing the format can improve speed
  and memory usage for large models. (#482)
