Changes in version 0.2.6 (2026-10-15)                  

  - Remove the internal numeric seed assignment from h_slice_sample().
    With seed = NULL, call h2o.runif() without a seed argument; only
    forward seeds explicitly supplied by the caller, with or without
    replacement.
  - Document optional seeds and test unseeded sampling and explicit-seed
    reproducibility in both sampling modes.

                        Changes in version 0.2.5                        

  - Display a period after section numbers in vignette headings and
    contents.

                        Changes in version 0.2.4                        

  - Add “à la dplyr” to the vignette title and index entry.
  - Separate and highlight the workflow in its own colored box.
  - Use the same blue styling for all eight Takeaway boxes.

                        Changes in version 0.2.3                        

  - Add bounded H2O value previews and explicit, visible tutorial
    assertions.
  - Improve vignette typography, tables, navigation and explanatory
    callouts with embedded CSS, without new runtime dependencies or
    external assets.
  - Document scalar retrieval for display and distinguish server-free
    rebuilds.

                        Changes in version 0.2.2                        

  - Render the species summary in the English vignette as a single
    formatted table, without interleaving Markdown output with the
    printing code.
  - Preserve the H2O calculations and all package functions unchanged.

                        Changes in version 0.2.1                        

  - Remove namespace instrumentation from distributed tests to comply
    with CRAN policy. Integration tests now compare H2O function
    bindings without mutation.
  - Preserve all 73 asserted examples and semantic regression tests.
  - Keep runtime download interception in separate maintainer tools that
    are not included in the source package.

                        Changes in version 0.2.0                        

  - First modular R package release, replacing the standalone prototype.
  - H2O is the only non-base runtime dependency; no local table
    fallback.
  - Closed remote expression interpreter and metadata-based selectors.
  - Remote summaries, including median and n_distinct; .by and .add
    support.
  - Remote full joins, relationship validation, semi and anti joins.
  - Correct missing comparisons, multiple sort keys, ties and zero-row
    slices.
  - Remote exact-size sampling, including replacement; remote lag and
    lead.
  - Remote text concatenation, reshaping and missing-value filling.
  - Intentional migration changes: h2o_tbl requires H2OFrame; h_collect
    returns H2OFrame; h_nest_by returns remote keys and a list of remote
    handles.
  - Unsupported grouped operations and arbitrary R callbacks fail
    explicitly.
  - Every export has an asserted example; English penguins vignette and
    tests.
