Changes in version 1.0.7 (2026-01-23)                  

Deprecated function dplyr::as.tbl is being removed from upstream, so
removing from PCCC package. Also, removing as_tibble.pccc_codes since S3
method as_tibble.pccc_codes calls as.data.frame.pccc_codes; upstream
tibble::as_tibble() alread calls as.data.frame.pccc_codes without our S3
method.

                 Changes in version 1.0.6 (2025-05-16)                  

Bug fixes

  - Code fixes -- most of these codes were flagging transplant but not
    the primary organ system; these were present in original publication
    but missing from this package
      - 996.83 added to CVD - it was flagging transplant but not CVD
      - 996.84 added to respiratory
      - 996.81 added to renal
      - 996.82, 996.86, 996.87 added to gi
      - ICD10 codes added to CVD: T86.20, T86.21, T86.22
      - M4330 is not a valid code, corrected to M433 (impacts
        congeni_genetic)
      - Add Z94.0 to transplant
  - Adjustment to build process removing C++11 requirement as now R
    build requires C++11 or newer.

Extensions

  - Update old urls and adding some links to wayback machine snapshots
  - Add key files to the package for reference

New functions:

  - S3 method as_tibble.pccc_codes has been added to the package to
    replace the deprecated as.tbl method since dplyr::as.tbl has been
    deprecated in favor of tibble::as_tibble

Deprecations:

  - as.tbl.pccc_codes has been deprecated since dplyr::as.tbl has been
    deprecated in favor of tibble::as_tibble

Defunct functions:

  - test_helper was an exported function that was used in the testing
    suite but not needed by any end user. It is now defunct.

                 Changes in version 1.0.5 (2020-06-02)                  

Changed included datafiles to be of type data.frame to avoid some
libraries trying to load data.table unnecessarily. Similarly removed
dependencies on dplyr::data_frame() due to deprecation.

Increased R dependency to version 3.5.0 and greater due to change in how
rds/rda files are created. Sample data included with package requires
newer R.

                 Changes in version 1.0.4 (2020-05-15)                  

Updates to make code work with 1.0 version of dplyr and new vctrs (dplyr
dependency). Removed use of dplyr from many tests.

Also update test cases to work with new R 4.0.x feature to account for
changed default to stringsAsFactors = FALSE.

                 Changes in version 1.0.3 (2019-08-21)                  

Added Rcpp::Shield() around Rcpp::wrap() calls inside
Rcpp::List::create(). Apparently adding shield helps with some
AddressSanitizer checks due to wrap calls inside List::create(). Thanks
to Tomas Kalibera for pointing that out.

Also updated a few tests to address deprecations in dplyr and changes in
testthat.

                 Changes in version 1.0.2 (2018-07-02)                  

Removed unnecessary initializer that causes problems with older
pre-C++11 compilers

                 Changes in version 1.0.1 (2018-03-10)                  

Minor update to address problem introduced by downstream dependency
package rlang 0.2.0. Unit tests identified that a null argument that
previously worked with enquo() now throws an error. Now check for
argument and set sane default if missing.

                 Changes in version 1.0.0 (2017-12-13)                  

After careful review of which ICD codes should flag which CCCs, we have
made tweaks to the overall logic as well as the various CCC categories.

                     Changes in version 0.2.2.9000                      

API Change

  - With the move to dplyr (>= 0.7.0) (#20) the API is cleaner and
    easier to use. See the vignette and examples. The major change is
    that dplyr::vars is no longer needed.

                        Changes in version 0.2.0                        

API Change

  - The ccc function only takes one entry for codes. There is no need to
    input the diagnostic and procedure codes separately.

Non-User Visible Changes

  - Redesign of the C++ code. Improved speed, fewer arguments, fewer
    operations.

                        Changes in version 0.1.1
