Changes in version 2026-4-22                      

Breaking Changes

This is a minor release including bug repairs and elimination of a
defunct package dependency.

Modified

  - Removed YRmisc dependency from namespace and repaired
    compute_lagcorr function that relied upon on it, replacing the
    original with a base R alternative
  - Modified read_dyads and read_1file functions to repair column header
    name TextRaw so that it matched text_raw that is used in subsequent
    cleaning steps
  - Incremented version number

                     Changes in version 2025-10-12                      

Breaking Changes

This is a major release including several new features and small
changes.

Added

  - New function generate_shams to shuffle the order of interlocutor
    turns within each conversation. This creates a group of control
    conversations.
  - New argument remove_backchannel in prep_dyads allows users to remove
    turns composed entirely of stopwords, preventing them from being
    filled in later stages.

Modified

  - summarize_dyads now computes dAUC for a lagged time series in
    addition to the unchanged. This is designed to account for both ways
    that interlocutors can be paired in each exchange.
  - Updated names of standardized dAUC columns to reflect that they are
    standardized to 50 turns.
  - Updates to documentation and website for new and modified features.

                      Changes in version 2025-7-29                      

Breaking changes

This is a minor release involving one bug repair

Modified

  - prep_dyads() added several missing cleaning functions that had been
    inadvertantly omitted during an earlier merge in preparation for
    CRAN

                      Changes in version 2025-7-21                      

Breaking changes

This is a minor release involving mostly optimization of functions.

Added

  - Software license now LGPL 3.0

Modified

  - Omitted prior GPL software license
  - Path to Journal of Open Source Software (JOSS) now points to main

                      Changes in version 2025-7-15                      

Breaking changes

This is a major release. We have included many new features and fixed
numerous bugs.

Added

  - Added news (you're reading it now), discussions, and issues/bug
    tracker to Github repo
  - prep_dyads() that combines two previous preparation steps
    clean_dyads() and align_dyads()
  - New function read_1file() that formats a conversation transcript
    already in your R environment
  - Improved handling of contractions with error detection/substition of
    non-ASCII character apostrophes. Contraction expansion (e.g.,
    'they're' to 'they are') now handled by a separate internal function
    call using custom regex.
  - Added argument omit_stops to prep_dyads specifying optional stopword
    removal
  - Added argument which_stoplist to `prep_dyads`` specifying a four
    stopword list options (SMART_stops, MIT_stops, Temple_stops25,
    CA_orig_stops).
  - Added pdf manual for ConversationAlign
  - Validation checks to read_dyads() will throw error and warning
    message if any transcript has more than or less than two
    participants for any individual conversation (Event_ID)
  - Added corpus_analytics() function that produces a variety of
    descriptive summary statistics (e.g., n-conversations, type token
    ratio, average turn length) in a table format.

Modified

  - summarize_dyads() restructured in significant ways including the
    addition of three new arguments: custom_lags default lags for
    correlation are set at -2.0,2 users are free to specifiy additional
    lags , default is NULL, sumdat_only produces a summary dataframe
    with values averaged to two rows per conversation (one for each
    participant, corr_type specifies correlation to apply to lagged data
  - Resampling of AUC in summarize_dyads() has been omitted in favor of
    proportionally rescaling dAUC to a standardized/fixed number of
    turns (100)
  - Modified internal lookup datase lookup_db, replaced with
    lookup_Jul25, includes many more dimensions and options for scaled
    vs. raw versions of variables
  - Moved all internal data to a different repository
    (ConversationAlign_Data) in order to get the package within CRAN
    file size constraints. Package now loads data from external HTTPs
    source
  - Omitted outside calls to libraries from functions

Fixed

  - Warnings and checks (variable names, etc) to read, clean, align
    functions

Deprecated

  - We are in the process of phasing out our original stopword list from
    earlier versions of ConversationAlign (pre 2025). We have included
    the old list as an optional call to the argument clean_dyads() as
    CA_OriginalStops. However, the default stopword list is new -
    Temple_Stops25
  - Eliminated several dimensions from lookup database: prevalence,
    hope, stress, politeness, empathy, prevalence, closeness,
    encouragement, hope, doubt, hostility, surprise
  - clean_dyads() and align_dyads()
