Changes in version 0.0.10 (2026-05-07)                 

  - The allow_null entry now works when as_is = TRUE fixing the
    erroneous implementation of the previous release. The check will now
    also only check unclassed lists (i.e. where is.object(x) == FALSE)
    and will stop recursing at this point.

                 Changes in version 0.0.9 (2026-03-16)                  

  - load_config() and list_config() gain an entry allow_null to control
    whether NULL entries are permitted. If FALSE then a NULL entry will
    trigger an error. This new argument defaults to TRUE for backwards
    compatibility.

  - Minor change to documentation example.

  - Vignette tweaks and change of underlying vignette engine back to
    litedown.

                 Changes in version 0.0.8 (2026-01-12)                  

  - load_config() (and consequently list_config()) gain an argument,
    strict. If TRUE (default and backwards compatible) then only the
    documented subset of base R functions can be used within the
    configuration file. If FALSE, the entire base namespace is made
    available (in particular, ::, which allows other calling of other
    packages).

                 Changes in version 0.0.7 (2025-12-06)                  

  - Fix bug when calling load_config() with config = NULL.

                 Changes in version 0.0.6 (2025-11-21)                  

  - Added modifyList() to the functions available within the
    configuration file.

  - Added the ability to pull specific configuration values out of the
    returned object when as_is = TRUE.

  - Added list_config(). This returns the names of all possible
    configurations within a file.

                 Changes in version 0.0.5 (2025-10-14)                  

  - Vignette tweaks and change of underlying vignette engine to quarto.

                 Changes in version 0.0.4 (2025-10-06)                  

  - Added file.path() to the functions available within the
    configuration file.

  - Improved documentation about injection functions in to the
    evaluation environment.

                 Changes in version 0.0.3 (2025-09-24)                  

  - Added the following to the functions to be usable in the
    configuration file:
    
      - getters: $, [ and [[
      - setters: $<-, [<- and [[<-

  - Removed length() and seq_along() from functions available in the
    configuration file.

  - Added the ability to injection functions in to the environment where
    the configuration file will be available. This is done by allowing
    the user to supply a list of crated functions (utilising
    carrier::crate()).

                 Changes in version 0.0.2 (2025-09-15)                  

  - CRAN (re)submission.

                        Changes in version 0.0.1                        

  - Initial CRAN submission.
