Changes in version 1.0.1 (2024-07-09)                  

  - Performance improvements.

                 Changes in version 1.0.0 (2024-06-11)                  

  - Removed Param objects. ParamSet now uses a data.table internally;
    individual parameters are more like Domain objects now. ParamSets
    should be constructed using the ps() shorthand and Domain objects.
    This entails the following major changes:
      - ParamSet now supports extra_trafo natively; it behaves like
        .extra_trafo of the ps() call.
      - ParamSet has $constraint
      - ParamSet objects are now less mutable. The only properties that
        can be changed are values, tags, deps, constraint and
        extra_trafo.
      - ParamSet$is_bounded is a vector with an entry for each
        parameter. Use $all_bounded for the previous behavior.
      - Condition objects are now S3 objects and can be constructed with
        CondEqual() and CondAnyOf(), instead of CondXyz$new(). (It is
        recommended to use the Domain interface for conditions, which
        has not changed)
      - ParamSet has new fields $is_logscale, $has_trafo_param
        (per-param), and $has_trafo_param (scalar for the whole set).
  - Added a vignette which was previously a chapter in the mlr3book
  - feat: added support for InternalTuneTokens

                 Changes in version 0.11.1 (2023-03-17)

  - feat: The function generate_design_sobol() generates a space-filling
    Sobol sequence design.
  - refactor: $set_values returns the parameter set invisible.

                 Changes in version 0.10.0 (2022-08-05)                 

  - Reset .has_extra_trafo to FALSE when trafo is set to NULL.
  - rd_info.ParamSet collapses vector with "\n" due changes in
    roxygen 7.2.0
  - Add method set_values() to conveniently add parameter values.

                 Changes in version 0.9.0 (2022-04-18)                  

  - Added default_values() function to extract default values from
    ParamSet objects.

                 Changes in version 0.8.0 (2022-01-31)

    loaded.
  - Fixed some links.

                 Changes in version 0.7.1 (2021-03-07)                  

  - Sampler1D also accept ParamSets with one Param now (#335).
  - Fixed sampling zero rows in Sampler1DRfun (#338).
  - to_tune(), p_dbl(), and p_int() accept logscale argument for tuning
    on a logarithmic scale.
  - to_tune can be called with only lower or only upper now and will
    infer the other bound if possible.

                 Changes in version 0.7.0 (2021-01-23)                  

  - ParamSet$get_values() checks whether all required parameter values
    are set. Required parameter are not checked anymore when new values
    are added to the parameter set.
  - ParamSet$check_dt() accepts data.frames.
  - Rename is_numeric and is_categorical to all_numeric and
    all_categorical.
  - Rename requires to depends.

                 Changes in version 0.6.0 (2020-12-04)                  

  - ps() shortcuts for ParamSet construction, with new Domain construct
    and constructors p_dbl, p_int, p_lgl, p_fct, and p_uty.
  - ParamSet$search_space() method that constructs tunable ParamSet from
    TuneToken objects, which are constructed with to_tune().

                 Changes in version 0.5.0 (2020-10-21)                  

  - Compact in-memory representation of R6 objects to save space when
    saving objects via saveRDS(), serialize() etc.
  - Improved performance for ParamSetCollection.

                 Changes in version 0.4.0 (2020-07-21)                  

  - New public methods is_numeric() and is_categorical() for parameter
    sets.
  - Fixed a test for upcoming release of data.table().
  - Added a helper function to format parameter sets in Rd files.

                 Changes in version 0.3.0 (2020-07-07)                  

  - New function transpose() converts data.table of parameter values to
    a list of lists.
  - New methods ParamSet$check_dt(), $assert_dt() and test_dt() can
    check a data.table for valid parameter values.
  - Documentation updated.
  - Unified style for object printers.

                 Changes in version 0.2.0 (2020-04-15)                  

  - Fixed warnings about partial argument matching.
  - Enforce integer bounds in ParamInt (#258).
