Changes in version 21-02-22                       

  - removed dependency on the data.table package
  - functions multicast, mc_metadata, mc_referents, and mc_clauses have
    been fully rewritten to output data.frames instead of data.tables
  - the version index (as retrieved by function mc_index) now includes
    the number of corpora in each version of the collection instead of
    an explicit list of corpora and has a slightly reshuffled column
    order
  - removed the mc_table function for its lack of practical utility
  - removed a number of previously hidden functions for file conversion;
    these will be made available in the future as a standalone package
    available from the Multi-CAST website
  - consequently, multicastR no longer imports a number of packages
    (stringi, curl, xml2, XML, xtable, gsubfn) used by these functions

                      Changes in version 19-08-30                       

  - the reflex column in multicastR tables has been renamed to isnref
  - function mc_referents now takes an optional argument vkey to select
    specific versions of the lists of referents
  - function mc_metadata now takes an optional argument vkey to select
    specific versions of the metadata
  - updated repository links
  - updated documentation
  - removed the legacy.colnames argument from function multicast
  - removed function mcindex (use mc_index instead)
  - removed function mc_count_clauses (use mc_clauses instead)

                      Changes in version 19-07-30                       

  - new function mc_metadata: download a table containing all corpus
    metadata from the repository
  - new function mc_referents: download a bundled list of all discourse
    referents (as annotated with the RefIND scheme, Schiborr et
    al. 2018) from the repository
  - new function mc_clauses: replaces function mc_count_clauses
  - function mc_count_clauses is now deprecated

    TRUE

  - the file column in multicastR tables has been renamed to text
  - the word column in multicastR tables has been renamed to gword
  - for backwards compatibility, the multicast function now has a
    legacy.colnames argument that, if set to TRUE, outputs tables with
    the old column names; this option will be removed in the future

    number of clause units in each corpus or text
