h2oplyr 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.

h2oplyr 0.2.5

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

h2oplyr 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.

h2oplyr 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.

h2oplyr 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.

h2oplyr 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.

h2oplyr 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.
