Changes in version 0.2.3.9006                      

  - C++ DAG engine (src/dag.cpp, 882 lines): All graph operations
    (node/edge add/remove, topological ordering, reachability queries)
    now run at C++ speed via Rcpp external pointers and .Call interface.
    This eliminates the R object overhead for dependency resolution.
  - New and improved pip_* API: Functional API replacing the R6 Pipeline
    class — pip_new(), pip_add(), pip_run(), pip_replace(), pip_clone(),
    pip_bind(), etc.
  - Execution modes (auto/split/reduce/plain): Native support for
    map-reduce style workflows where steps can split output into named
    partitions and downstream steps auto-map over them.
  - Backward compatibility: Legacy pipe_* functions and Pipeline R6
    class preserved as deprecated aliases (R/aliases.R, R/pipelineR6.R).
  - pip_view() — create filtered pipeline views (by dependencies, tags)
  - pip_tag() / pip_untag()
  - [[ extract operator for pipelines
  - Comprehensive revision of all vignettes to match new API
  - MIT license, updated CI workflows, dependabot config, kilo.json,
    lintr/styler config
  - Extensive test suite (~10K+ lines) covering C++ DAG, pip_* API,
    aliases, execution modes, and recursive runs

                     Changes in version 0.2.3.9005                      

  - deprecate legacy pipe_* API in favor of the new pip_* API
  - deprecate legacy Pipeline R6 interface (Pipeline$new())

  - refactor: deprecate keepOut field and introduce tags field

                     Changes in version 0.2.3.9004                      

  - deprecate all parameter in pipe_collect_out()
  - deprecate pipe_set_data_split() and pipe_set_keep_out()
  - add new functions to skip and unskip pipeline steps and groups:
    pipe_skip_step(), pipe_unskip_step(), pipe_skip_group(), and
    pipe_unskip_group().
  - add new function, pipe_get_step_field() to retrieve a specific field
    of a pipeline step
  - remove advanced vignette on using pipeflow with split data sets

                     Changes in version 0.2.3.9003                      

  - Refactor: Remove Param object handling from pipeline and utility
    functions
  - Refactor: Remove unused get_params_unique_json method and its
    documentation

                     Changes in version 0.2.3.9002                      

  - refactor: ensure unit tests for logging is always done with logging
    enabled
  - refactor: add 'locked' column and improve indexing performance
  - refactor: implement slightly faster step existence check
  - feat: set locked status via boolean flag and add has_step_locked
    function

                     Changes in version 0.2.3.9001                      

  - feat: implement index map and BFS for dependency graphs (improved
    performance)
  - chore: add benchmark for running long linear pipelines

                     Changes in version 0.2.3.9000                      

  - Same as previous version.
