Changes in version 1.6.0 (2025-10-15)                  

Minor Changes

  - Dropped C++11 specification causing warning messages

                 Changes in version 1.5.0 (2022-12-03)                  

Minor Changes

  - Addressed warning messages about bitwise operators in C++ code
  - Removed 'boost' C++ libraries because no longer using for
    distribution functions

                 Changes in version 1.4.0 (2021-09-24)                  

Minor Changes

  - All Cat objects are reverted to the bounds of [-5,5]. Likewise, the
    Cat class defaults are now [-5,5].

  - Newton Raphson bug fixed. Bug was causing estimates when no
    questions have been answered to go to extremes rather than prior
    mean.

  - simulateThetas() has a new argument (defaulted to FALSE for
    backwards compatibility) that when TRUE returns a list of dataframes
    containing adaptive answer profiles for each Cat objected involved
    in the simulation

                 Changes in version 1.3.0 (2020-10-06)                  

Minor Changes

  - All Cat objects now use integration bounds of [-4,4]. Likewise, the
    Cat class defaults are now [-4,4]. This narrows the bounds of
    integration from [-5,5] to avoid computational issues that arise at
    "extreme" values of the latent trait.

  - Cat object z slot still defaults to .9, but now in calculating delta
    for certain integration routines, the package executes qnorm(z).

  - oracle() function adds option for parallel computing using plyr

  - probability() for categorical data now throws errors to account for
    extreme values of latent trait that may cause computational issues

                 Changes in version 1.2.0 (2019-12-09)                  

Minor Changes

  - simulateRespondents() bug fix when respondent's answer in raw data
    is NA, now transform to -1 to indicate a skip

  - added dataset of Need to Evaluate raw response profiles

  - readQualtrics() now has respondent ID as rownames instead of a
    column.

  - Added example data for the readQualtrics() function.

                 Changes in version 1.1.3 (2019-11-19)                  

Major Changes

  - New functions simulateRespondents(), simulateThetas(),
    simulateFisherInfo(), and oracle() allow for simulation exercises to
    evaluate model quality and performace.

  - New function plot.Cat() allows for visual representation of item
    parameters.

  - New functions fromJSONCat(), toJSONCat(), and readQualtrics() aid
    the user in creating an adaptive battery in Qualtrics using catSurv.

Minor Changes

  - The slot ids was added to the Cat object representing each question
    item's unique identifier.

  - selectItem() returns a third item, next_item_name which represents
    the unique identifier of the item that should be asked next.

  - lookAhead() now returns the next best item given the question is
    skipped.

                 Changes in version 1.0.3 (2017-07-05)                  

Major Changes

  - New functions estimateThetas() and simulateThetas() allow for
    estimation of ability parameter for dataframe of response sets.

Minor Changes

  - Streamlined checkStopRules().

                 Changes in version 1.0.2 (2017-06-26)                  

Major Changes

  - Parallelized main functionality of package --- selectItem().

Bug Fixes

  - Fixed bug in ltmCat(), tpmCat(), grmCat(), and gpcmCat() by adding
    the ltm package to Imports.
  - Fixed bug in KL functions, where we were integrating over a function
    that itself called integration.
  - Removed versioning from stats and methods imports as it caused
    errors in testing with r-oldrel.

                 Changes in version 1.0.1 (2017-06-16)                  

  - Corrected errors regarding portability of code to Solaris operating
    systems.
